This commit adds the feature where the CAN ISR will continue to
run even if the cache is disabled. Whilst cache is disabled, any
received messages will go into the RX queue, and any pending TX
messages in the TX queue will be transmitted. This feature should
be enabled using the CONFIG_CAN_ISR_IN_IRAM option.
This commit simplifies the defines made in the _caps.h header. Kconfig
option dependencies were moved into the LL, and the check for a
valid BRP has bee simplified.
The following commit refactors the CAN driver such that
it is split into HAL and Lowlevel layers. The following
changes have also been made:
- Added bit field members to can_message_t as alternative
to message flags. Updated examples and docs accordingly
- Register field names and fields of can_dev_t updated
This commit removes any function calls within
the CAN driver that result in a call to ESP_LOG
whilst inside a critical section.
These function calls are either moved outside
critical sections (e.g., intr_alloc and gpio
functions), or substituted (e.g., assert()).
Closes https://github.com/espressif/esp-idf/issues/4412
This commit fixes multiple bugs caused by incorrect calls to
can_enter_reset_mode() and can_exit_reset_mode. Example test
scripts also updated to match new runners.
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
This commits adds the functions can_clear_transmit_queue() and
can_clear_receive_queue(). Closes#2906
The following bug are fixed:
- CAN_IO_UNUSED is now explicitly cast to enum type. Closes#2825
- Fix multiple documentation errors. Closes#2898, Closes#2794
- can_reconfigure_alerts() returns incorrect current_alerts. Closes#3028
- Add missing header file. Closes#3065
This commit does the following
- Add power management lock to CAN driver so that APB frequency does not change
whilst CAN driver is in use
- Fix incorrect flag in can_transmit()
- Refactor can_driver_install() and can_driver_uninstall() so that critical sections
are shorter
- Fix CAN gpio configuration bug on RX pin. Closes#2302
- Add docs about multiple ID configuration and fix example links
