Alex Mikhalev	6bd4dff51f	drivers/smbus: Increase max block size to 34 ... batt_smbus for BQ40Z80 transfers up to 34 bytes (32 byte block + 2 byte address), but this was overflowing and failing the PEC check. So increase the buffer size Signed-off-by: Alex Mikhalev <alex@corvus-robotics.com>	2021-02-18 07:52:26 -05:00
flochir	ec7108892b	batt_smbus: fix potential hardfault by checking buffer sizes (#15789) ... * Added buffer length check to SMBus::block_read (triggered hardfault in batt_smbus module by writing beyond buffer end due to device returning longer byte_count than requested/expected) Co-authored-by: Florian Olbrich <florian.olbrich@scarabot.de> Co-authored-by: Daniel Agar <daniel@agar.ca> Co-authored-by: BazookaJoe1900 <BazookaJoe1900@gmail.com> Co-authored-by: Beat Küng <beat-kueng@gmx.net>	2020-09-28 09:41:40 +02:00
bazooka joe	190b96a46c	SMbus battery driver - a lot of updates and optimizations ... - added support for BQ40Z80 based battery - added performance counter for interface errors - added SMART_BATTERY_INFO mavlink message - general code cleanups and optimization - fixed: void flooding the log in case of interface error - fixed: using _batt_startup_capacity instead of _batt_capacity for discharged_mah - update: read manufacture_date - update: get _cell_count from parameter and not const 4 - update: avoid re-reading data that has already been read and stored on class already - currently the battery type defined by BAT_SMBUS_MODEL parameter and not by auto detection	2020-08-18 21:41:19 -04:00

Beat Küng	32359168d6	smbus: fix invalid memory access in read_word() ... read_word() expected 3 bytes (uint16_t + PEC byte), but was passed an address to an uint16_t value. write_word() is changed to be type-safe as well.	2019-11-07 10:56:27 +01:00
