ChibiOS Free Embedded RTOS

I'm currently working on creating a driver for an external SPI to CAN device. I would like to use the hal_can abstraction, but the way HAL is currently designed is that it is directly linked to the hal_<device>_lld functions. I would like to use the HAL to be more than just bound to MCU built-in per...

hal_can.h should define the CANRxFrame/CANTxFrame structures. The structure definitions are currently entirely inside hal_can_lld.h . If there are any platform specific members needed (for example, FMI and TIME in STM32), those should be in macros defined in hal_can_lld.h, and included at the end of...

Is it true that (assuming no overflow happens), the total time logged by stats for all threads should track the current system time? Also, that the cumulative time for each thread is the actual execution time of the thread + any interrupts that occurred in the thread. The stats timer for the thread ...

Also, check if the latest trunk code already has the fix.

Submit bug report to STMicro, on their forums perhaps?

No problem, I'm working in trunk. I'm using Alex mirror in GitHub . I'll try using my "driver", if it works, I'd like to ask some directions to write a STM32 internal flash driver if you believe is the right path. Thanks again. Check this out: http://www.chibios.com/forum/viewtopic.php?f=...

Yep, definition of callback has changed. Check out hal_dac.h. now, it only takes the driver strict as a parameter.

See viewtopic.php?f=3&t=4929. I believe the demos in testhal have been updated as well to show the usage of the new API.

Giovanni doesn't have anything to do with the Github mirror. The official ChibiOS repo is on sourceforge. Yeah, a lot of us don't like that, but it is what it is :). Also, please post more information on that warning. Post the file, and more context from the compiler output .. Clearly, your callback...

What if you disconnect the SPI lines going to the slave device and enable the internal pull-up on MISO? When you do the SPI transaction, you should receive all 0xFF.

Those are different, ObjFIFOs are meant to exchange fixed-size structures in a copy-less way. HAL I/O buffers are used in those situations where you have to read/write byte streams from one side and fetch/post buffers from the other side, it is more of a buffering system. Which is better depends on...
