- Changes: b195315b86...1f339cdf5c
1f339cd 2021-03-20 Dongoo Lee - Pass ros_distro in CMakeLists.txt instaed of checking it in jinja_gen.py (#712)
1b1afca 2021-03-18 David Jablonski - gst camera: add RTMP streaming and nvidia encoding (#727)
- debug output is now printed & filtered with the python 'logging' standard module
- changed 'module whitelist' to 'scope-whitelist'
- whitelist may now apply to libraries
- libraries are not included by default
- may be merged with their depending modules with the `--merge-depends` cli flag
- eliminates redundant 'special-case' handling code
- greatly expands debugging output
- fixes debug output if package dependencies are missing
- still crashes on error matches
- now warns on ambiguous matches
- prints a list of ambiguous source sites (aka warnings) on completion
- adds warnings if any of the source paths are invalid
- do not emit debug output for modules outside of the module/scope whitelist
- Expand script's CLI parameters
- added 'none' output options: undocumented debugging option to silence file output while debugging
- added the `--merge-depends` cli flag -- merges output of modules & their dependee libraries
- Source processing now happens on original source files:
- processing to line-by-line
- required overhaul of regex match patterns + processing
- pros:
- enable tracing of ambiguous parsing sites -- reports (module, file, line-number, line-contents)
- simplifies code
- reduces computational complexity
- cons:
- certain declarations are harder to parse (multiline arrays)
- refactors:
- added specific subclasses for each: Publications, Subscriptions, Ambiguities
- added a "Scope" class to represent either a module ('ModuleScope') or a library ('LibraryScope')
With this change we prevent the case where arming silently fails within
the first 10 seconds after boot.
Also, we now set the sensors as healthy as soon as the ekf is healthy,
and don't wait 10 seconds without actually checking.
The user-defined literals for milli- and microseconds
should have argument names matching their units. The
current argument names 'seconds' is probably an oversight.
Refering to the refernece manual:
Tx queue operation is configured by programming FDCAN_TXBC.TFQM to 1. Messages
stored in the Tx queue are transmitted starting with the message with the lowest message
ID (highest priority). **In case that multiple queue buffers are configured with the same
message ID, the queue buffer with the lowest buffer number is transmitted first**
Tx FIFO operation is configured by programming FDCAN_TXBC.TFQM to 0. Messages
stored in the Tx FIFO are transmitted starting with the message referenced by the get index
FDCAN_TXFQS.TFGI. After each transmission the get index is incremented cyclically until
the Tx FIFO is empty. The Tx FIFO enables transmission of messages with the same
message ID from different Tx buffers in the order these messages have been written to the
Tx FIFO
The issue will be cancelation:
The FDCAN supports transmit cancellation. To cancel a requested transmission from a
dedicated Tx buffer or a Tx queue buffer the Host has to write a 1 to the corresponding bit
position (= number of Tx buffer) of register FDCAN_TXBCR. Transmit cancellation is not
intended for Tx FIFO operation.
But there is nothing preventing it. This seems to indicate it will
work. When a transmission request for the Tx buffer referenced by the get index is canceled, the
get index is incremented to the next Tx buffer with pending transmission request and the Tx
FIFO free level is recalculated. When transmission cancellation is applied to any other Tx
buffer, the get index and the FIFO free level remain unchanged.
