with new safer classes from uavcan/time.hpp; generated types were moved away from anonymous namespaces because this makes it impossible to use a type from different compilation units.

For more info see section below
+ *
Last data handling in slave
+ * If the user wants to implement a slave which will read a byte from a specific location over and over + * again whenever master reads the slave. If the user initializes the xfer->txBuff as the location to read + * the byte from and xfer->txSz as 1, then say, if master reads one byte; slave will send the byte read from + * xfer->txBuff and will call the event handler with #I2C_EVENT_DONE. If the master attempts to read another + * byte instead of sending the byte read from xfer->txBuff the slave hardware will send 0xFF and no event will + * occur. To handle this issue, slave should set xfer->txSz to 2, in which case when master reads the byte + * event handler will be called with #I2C_EVENT_SLAVE_TX, in which the slave implementation can reset the buffer + * and size back to original location (i.e, xfer->txBuff--, xfer->txSz++), if the master reads another byte + * in the same transfer, byte read from xfer->txBuff will be sent and #I2C_EVENT_SLAVE_TX will be called again, and + * the process repeats. + */ +void Chip_I2C_SlaveSetup(I2C_ID_T id, + I2C_SLAVE_ID sid, + I2C_XFER_T *xfer, + I2C_EVENTHANDLER_T event, + uint8_t addrMask); + +/** + * @brief I2C Slave event handler + * @param id : I2C peripheral ID (I2C0, I2C1 ... etc) + * @return Nothing + */ +void Chip_I2C_SlaveStateHandler(I2C_ID_T id); + +/** + * @brief I2C peripheral state change checking + * @param id : I2C peripheral ID (I2C0, I2C1 ... etc) + * @return 1 if I2C peripheral @a id has changed its state, + * 0 if there is no state change + * @note + * This function must be used by the application when + * the polling has to be done based on state change. + */ +int Chip_I2C_IsStateChanged(I2C_ID_T id); + +#endif /* !defined(CHIP_LPC110X) */ + +/** + * @} + */ + + #ifdef __cplusplus +} +#endif + +#endif /* __I2C_11XX_H_ */ diff --git a/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h b/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h new file mode 100755 index 0000000000..be83679515 --- /dev/null +++ b/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h @@ -0,0 +1,288 @@ +/* + * @brief IOCON registers and control functions + * + * @note + * Copyright(C) NXP Semiconductors, 2012 + * All rights reserved. + * + * @par + * Software that is described herein is for illustrative purposes only + * which provides customers with programming information regarding the + * LPC products.

This algorithm is an -# optional extension to the UAVCAN specification, and it is not mandatory to -# support it. -# -# The dynamic Node ID allocation algorithm works as follows: -# -# - As a prerequisite, the network contains at least one node that has some -# Node ID assigned, that will handle allocation requests from other nodes. -# This node will be later referred to as Allocator. It is recognized that -# since UAVCAN is a decentralized network, there might be more than one -# Allocator, but only one of them should handle allocation requests at any -# given time. This issue is covered below in detail. -# -# - The network may also contain any number of nodes that seek to have -# Node IDs assigned to them. In order to get a Node ID assigned, these nodes -# make a request to the Allocator. Requesting nodes will be referred to as -# Allocatees. -# -# - In order to get a Node ID allocated, the Allocatee fills this message -# structure with its short unique ID (see below to learn how to compute one) -# and its preferred Node ID (which is basically the Node ID it would like to -# take, if possible). If the Allocatee doesn't have any preference, the -# preferred Node ID can be set to zero. -# -# - The Allocatee broadcasts the message to the bus. Since it doesn't have a -# Node ID at the moment, the field Source Node ID in the broadcasted message -# must be zero. Note that it may require special logic in the transport -# layer to receive messages where Source Node ID is zeroed. -# -# - The Allocator receives the message and refers to its Node ID Table, where -# it looks for any unallocated Node ID value that equal to or greater than -# the value that was requested by the Allocatee. If the desired Node ID is -# set to zero, or if all Node IDs that are larger than the preferred one are -# already taken, the Allocator traverses the Node ID Table from top to -# bottom (i.e. from high to low Node ID) until it finds first unallocated -# entry. In a case if all available entires are taken, the Allocator ignores -# the request. Please note that it is recommended to restrict the range of -# dynamically assignable Node IDs, as described below. -# -# - The Allocator fills the response message. The short unique ID is set the -# same as in the request, the Node ID field is assigned the value obtained -# on the previous step. When filled, the message is broadcasted as usual, -# i.e. the field Source Node ID must be set to the actual Node ID of the -# Allocator. This allows other Allocators, if any, to understand that this -# message is not an allocation request, otherwise Source Node ID would be -# zero. -# -# - The Allocatee receives the response. Sice there can be other nodes trying -# to get a Node ID at the same time, the Allocatee filters other messages -# by means of comparing its own short unique ID with short unique ID in the -# messages passing by. When a message is received such that its short unique -# ID equals the short unique ID of the Allocatee, the Allocatee gets the -# allocated Node ID from the message, accepts it and continues its normal -# operation as a full-fledged UAVCAN node. -# -# - It is recommended that once Allocatee was granted a Node ID, it stops -# listening to other messages of this type and reconfigures its CAN -# acceptance filters accordingly. -# -# It has been mentioned above that a network may accomodate more than one -# Allocator at the time. In this case, the Allocators should agree between -# each other that only one of them is handling allocation requests at the -# moment. A possible way to reach such an agreement is to let one Allocator -# monitor the presence of the second one (e.g. by means of listening to its -# NodeStatus messages), so that the second Allocator will ignore allocation -# requests as long as the first one is alive. -# -# Every Allocator must continuously maintain a table that indicates which -# Node IDs are taken, and which are free. The logic is like that: immediately -# after initialization, only one Node ID is considered to be taken - the one -# that belongs to the Allocator itself. The allocator subscribes to the -# messages uavcan.protocol.NodeStatus and this one, that are then used to -# update the table in real time - once a NodeStatus or this message are -# received, the table is updated to indicate that the Node ID that sent the -# NodeStatus message is taken. The Allocator must not process allocation -# requests sooner than a few seconds after its initialization, in order to -# ensure that all nodes that exist in the network were able to transmit their -# NodeStatus message at least once. The exact duration of initialization delay -# is defined in a constant below. -# -# In order to minimize chances of Node ID collision between nodes that rely on -# the dynamic allocation and the nodes that use statically allocated Node IDs, -# it is recommended to restrict the range of dynamically allocatable Node IDs. -# Two constants below define a range for dynamically allocated Node ID. -# -# There is a limit that restricts the maximum frequency at which the Allocatee -# is allowed to broadcast allocation requests.

In case if this default value is not appropriate + * for the end application, the request interval can be overriden via @ref setRequestInterval(). + * + * Following the above explained requirements, the default request interval is defined as follows: + * request interval [ms] = foor(5000 [ms] bootloader timeout / 123 nodes) + * Which yields 40 ms. + * + * Given default service timeout 500 ms and the defined above request frequency 40 ms, the maximum number of + * concurrent requests will be: + * max concurrent requests = ceil(500 [ms] timeout / 40 [ms] request interval) + * Which yields 13 requests. + * + * Keep the above equations in mind when changing the default request interval. + * + * Obviously, if all calls are completing in under (request interval), the number of concurrent requests will never + * exceed one. This is actually the most likely scenario. + * + * Note that all nodes are queried in a round-robin fashion, regardless of their uptime, number of requests made, etc. + * + * Events from this class can be routed to many listeners, @ref INodeInfoListener. */ class UAVCAN_EXPORT NodeInfoRetriever : NodeStatusMonitor , TimerBase @@ -135,8 +159,9 @@ private: } };

General Call Handling
- * Slave can receive data from master using general call address (0x00). General call - * handling must be setup as given below - * - Call Chip_I2C_SlaveSetup() with argument @a sid as I2C_SLAVE_GENERAL - * - xfer->slaveAddr ignored, argument @a addrMask ignored - * - function provided by @a event will registered to be called when slave received data using addr 0x00 - * - xfer->rxBuff and xfer->rxSz should be valid in argument @a xfer - * - To handle General Call only (No other slaves are configured) - * - Call Chip_I2C_SlaveSetup() with sid as I2C_SLAVE_X (X=0,1,2,3) - * - setup @a xfer with slaveAddr member set to 0, @a event is ignored hence can be NULL - * - provide @a addrMask (typically 0, if not you better be knowing what you are doing) - * - To handler General Call when other slave is active - * - Call Chip_I2C_SlaveSetup() with sid as I2C_SLAVE_X (X=0,1,2,3) - * - setup @a xfer with slaveAddr member set to 7-Bit Slave address [from Bit1 to 7] - * - Set Bit0 of @a xfer->slaveAddr as 1 - * - Provide appropriate @a addrMask - * - Argument @a event must point to function, that handles events from actual slaveAddress and not the GC - * @warning - * If the slave has only one byte in its txBuff, once that byte is transfered to master the event handler - * will be called for event #I2C_EVENT_DONE. If the master attempts to read more bytes in the same transfer - * then the slave hardware will send 0xFF to master till the end of transfer, event handler will not be - * called to notify this. For more info see section below
- *
Last data handling in slave
- * If the user wants to implement a slave which will read a byte from a specific location over and over - * again whenever master reads the slave. If the user initializes the xfer->txBuff as the location to read - * the byte from and xfer->txSz as 1, then say, if master reads one byte; slave will send the byte read from - * xfer->txBuff and will call the event handler with #I2C_EVENT_DONE. If the master attempts to read another - * byte instead of sending the byte read from xfer->txBuff the slave hardware will send 0xFF and no event will - * occur. To handle this issue, slave should set xfer->txSz to 2, in which case when master reads the byte - * event handler will be called with #I2C_EVENT_SLAVE_TX, in which the slave implementation can reset the buffer - * and size back to original location (i.e, xfer->txBuff--, xfer->txSz++), if the master reads another byte - * in the same transfer, byte read from xfer->txBuff will be sent and #I2C_EVENT_SLAVE_TX will be called again, and - * the process repeats. - */ -void Chip_I2C_SlaveSetup(I2C_ID_T id, - I2C_SLAVE_ID sid, - I2C_XFER_T *xfer, - I2C_EVENTHANDLER_T event, - uint8_t addrMask); - -/** - * @brief I2C Slave event handler - * @param id : I2C peripheral ID (I2C0, I2C1 ... etc) - * @return Nothing - */ -void Chip_I2C_SlaveStateHandler(I2C_ID_T id); - -/** - * @brief I2C peripheral state change checking - * @param id : I2C peripheral ID (I2C0, I2C1 ... etc) - * @return 1 if I2C peripheral @a id has changed its state, - * 0 if there is no state change - * @note - * This function must be used by the application when - * the polling has to be done based on state change. - */ -int Chip_I2C_IsStateChanged(I2C_ID_T id); - -#endif /* !defined(CHIP_LPC110X) */ - -/** - * @} - */ - - #ifdef __cplusplus -} -#endif - -#endif /* __I2C_11XX_H_ */ diff --git a/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h b/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h deleted file mode 100755 index be83679515..0000000000 --- a/libuavcan_drivers/lpc11c24/test_olimex_lpc_p11c24/lpc_chip_11cxx_lib/inc/iocon_11xx.h +++ /dev/null @@ -1,288 +0,0 @@ -/* - * @brief IOCON registers and control functions - * - * @note - * Copyright(C) NXP Semiconductors, 2012 - * All rights reserved. - * - * @par - * Software that is described herein is for illustrative purposes only - * which provides customers with programming information regarding the - * LPC products.

This alows a layered approch to file service. Setting the RootPath to an SD card and the AltRootPath to a ROM FS will allow a user to provide an updated uavcan firware file that will be used instead of the baked in one without any copying. The path as been removed from the interactions with nodes. There by supporting Non-compliant nodes that could not handle the specified path length. The vitrual pathing has been moved into the FDCache. --- .../include/uavcan/protocol/file_server.hpp | 55 ++- .../protocol/firmware_update_trigger.hpp | 8 +- .../basic_file_server_backend.hpp | 84 ++-- .../uavcan_posix/firmware_version_checker.hpp | 370 +++++++----------- 4 files changed, 250 insertions(+), 267 deletions(-) diff --git a/libuavcan/include/uavcan/protocol/file_server.hpp b/libuavcan/include/uavcan/protocol/file_server.hpp index f1ca877cd8..167be48fa9 100644 --- a/libuavcan/include/uavcan/protocol/file_server.hpp +++ b/libuavcan/include/uavcan/protocol/file_server.hpp @@ -25,11 +25,15 @@ namespace uavcan */ class UAVCAN_EXPORT IFileServerBackend { + public: typedef protocol::file::Path::FieldTypes::path Path; typedef protocol::file::EntryType EntryType; typedef protocol::file::Error Error; + IFileServerBackend::Path root_path_; + IFileServerBackend::Path alt_root_path_; + /** * All read operations must return this number of bytes, unless end of file is reached. */ @@ -40,6 +44,51 @@ public: */ static char getPathSeparator() { return static_cast(protocol::file::Path::SEPARATOR); } + /** + * Set a base path to the files. + */ + void setRootPath(const char * path) + { + if (path) + { + root_path_.clear(); + root_path_ = path; + if (root_path_.back() != getPathSeparator()) + { + root_path_.push_back(getPathSeparator()); + } + } + } + + void setAltRootPath(const char * path) + { + if (path) + { + alt_root_path_.clear(); + alt_root_path_ = path; + if (alt_root_path_.back() != getPathSeparator()) + { + alt_root_path_.push_back(getPathSeparator()); + } + } + } + + /** + * Get a base path to the files. + */ + Path& getRootPath() + { + return root_path_; + } + + /** + * Get a base path to the files. + */ + Path& getAltRootPath() + { + return alt_root_path_; + } + /** * Backend for uavcan.protocol.file.GetInfo. * Refer to uavcan.protocol.file.EntryType for the list of available bit flags. @@ -161,8 +210,11 @@ public: , backend_(backend) { } - int start() + int start(const char* server_root = UAVCAN_NULLPTR, const char* server_alt_root = UAVCAN_NULLPTR) { + backend_.setRootPath(server_root); + backend_.setAltRootPath(server_alt_root); + int res = get_info_srv_.start(GetInfoCallback(this, &BasicFileServer::handleGetInfo)); if (res < 0) { @@ -224,6 +276,7 @@ class FileServer : protected BasicFileServer resp.entry_type, resp.entry_full_path.path); } + public: FileServer(INode& node, IFileServerBackend& backend) : BasicFileServer(node, backend) diff --git a/libuavcan/include/uavcan/protocol/firmware_update_trigger.hpp b/libuavcan/include/uavcan/protocol/firmware_update_trigger.hpp index 5b0d019481..04de3be0d2 100644 --- a/libuavcan/include/uavcan/protocol/firmware_update_trigger.hpp +++ b/libuavcan/include/uavcan/protocol/firmware_update_trigger.hpp @@ -345,12 +345,7 @@ class FirmwareUpdateTrigger : public INodeInfoListener, protocol::file::BeginFirmwareUpdate::Request req; req.source_node_id = getNode().getNodeID().get(); - if (!common_path_prefix_.empty()) - { - req.image_file_remote_path.path += common_path_prefix_.c_str(); - req.image_file_remote_path.path.push_back(protocol::file::Path::SEPARATOR); - } - req.image_file_remote_path.path += path->c_str(); + req.image_file_remote_path.path = path->c_str(); UAVCAN_TRACE("FirmwareUpdateTrigger", "Request to %d with path: %s", int(node_id.get()), req.image_file_remote_path.path.c_str()); @@ -396,6 +391,7 @@ public: */ int start(NodeInfoRetriever& node_info_retriever, const FirmwareFilePath& arg_common_path_prefix = FirmwareFilePath(), + const FirmwareFilePath& arg_alt_path_prefix = FirmwareFilePath(), const TransferPriority priority = TransferPriority::OneHigherThanLowest) { /* diff --git a/libuavcan_drivers/posix/include/uavcan_posix/basic_file_server_backend.hpp b/libuavcan_drivers/posix/include/uavcan_posix/basic_file_server_backend.hpp index eec15f99d3..14f3672030 100644 --- a/libuavcan_drivers/posix/include/uavcan_posix/basic_file_server_backend.hpp +++ b/libuavcan_drivers/posix/include/uavcan_posix/basic_file_server_backend.hpp @@ -1,6 +1,6 @@ /**************************************************************************** * -* Copyright (c) 2015 PX4 Development Team.
