Hi, is there any way to generate microsecond pulses on a GPIO line using MP where the pulse width could be configurable in multiples of micro seconds? The minimum is one pulse. I have an idea to use the timer callback to trigger a GPIO line but I am not sure if the processing is fast enough to do th...

In stmhal/boards/PYBV10/mpconfigboard.h

When setting:
MICROPY_HW_ENABLE_CC3K (1)

The build gives many errors.

Hi, I am in the process of integrating ChibiOS with MP. I think that could be useful to build a threading library based on this RTOS. I am still having problems with incompatible definitions and build, between the two. The idea is to have MP run on top of this RTOS in one thread and take advangtage ...

Ok that makes sense. Thank you.

I am not sure why the following causes and exception with MemoryError when a divide by 3 is added: adcY11 = pyb.ADC( pyb.Pin.board.Y11 ) adcTimer = pyb.Timer(7, freq=2) # THIS WORKS FINE adcTimer.callback(lambda t: print(adcY11.read() ) ) # THIS GIVES MemoryError exception adcTimer.callback(lambda t...

That should be simple enough to enable/disable with the configuration files.
I can try it, but I believe that the RTOS can be totally disabled unless you wish to use its drivers in a single thread environment.
I think it makes sense to have the RTOS be built as a static library.

I am starting on integrating the ChibiOS RTOS with MP. I would like to get some feedback on what would be more beneficial: MP as a library or ChibiOS as a library. Either modules can be compiled as a static library. Here are some thoughts to consider: 1. ChibiOS implements drivers for just about all...

This is great. Thank you.

Did someone build MP as a static library, to be linked with an application?
If so please provide Makefile (hopefully some slight changes). Thanks.

Sure, already done, issue #743
