ChibiOS Free Embedded RTOS

If I understand the example code, it is demonstrating the use of events. In the first example application it demonstrates polling for an event.
The second application demonstrates issuing an event in a callback that is triggered by an interrupt (the main while loop also listens for the event).

It ...

I have been following some example to write an interrupt handler, but failed to compile with the following:
./os/hal/ports/STM32/LLD/EXTIv1/hal_ext_lld.h:30:29: fatal error: hal_ext_lld_isr.h: No such file or directory
That has led me to this forum thread.

Are the 'events' referred to in this demo ...

Now that I have my master side built up, I don't quite have this working yet.

It is likely a configuration issue though I am not 100% certain I understand the behavior of this function in terms of execution and program flow.

This spiStartSendI() will send a byte to the SPI buffer via DMA.
The ...

Thank you very much plyatov! That is a great help.

I'd like to bump this thread as I need to do the same thing.

I have implemented plyatov's method of adding a switch in the spiConfig to bypass the hard coded MSTR setting on the SPI_CR1.

I'm not sure which chibi spi methods I should call to handle a transaction of data from the salve to the master ...

I have a couple of threads reading from different devices, one is on SPI1 and the other is SPI2. My code is crashing and after doing some reading I am beginning to think the conflict is in the DMA.

There are no shared resources between threads and they won't work unless I reduce the priority of ...

Thank you for the quick response Giovanni

I will look into the Objects FIFO.

Thank you

I am currently trying to implement a producer/consumer data flow between two threads. At some point in the future these threads will be converted to ISRs. I am assuming it is possible that I can implement this in a way that works in both contexts (thread/ISR).

I have one thread that gets samples ...

The combination of compilers works just fine:

gcc version 5.4.0
gcc version 5.4.0
arm-none-eabi-gcc-4.9.3

I was just using my debugger incorrectly

I have this same issue with chThdSleepMilliseconds not returning, it is stuck in waiting for interrupt.

I have installed:

gcc version 5.4.0
gcc version 5.4.0
arm-none-eabi-gcc-4.9.3

Which is the recommended solution here? roll back gcc and g++ to 4.7 or replace arm-none-eabi with gcc-arm ...
