Hello, I am wondering if the following File functions are reliably working and were tested: - file and directory creation - file open with append flag - file seek - file flush - file close I did some timing measurement, it seems that most of these functions take about 40ms to execute. I am curious w...

ok great. I will be waiting for your changes. Thank you.

Do you think this could be an easy fix?
If not please let me know. Thanks.

Hello, I am trying to use the timer functionality on Y11/B0 and I don't seem to get it to work as on other pins. t = pyb.Timer(1, freq=1000, mode=pyb.Timer.CENTER) ch2 = t.channel(2, pyb.Timer.PWM, pin=pyb.Pin.board.Y11, pulse_width=(t.period() + 1) // 2) The datasheet shows: PB0: TIM1_CH2N, TIM3_CH...

Is there any watchdog timer functionality using the STM hardware WDT?

I can zip what I have and send it to you somehow. We could chat over Skype if you'd like. The older ChibiOS used to use the ST library, I looked recently and you are right it is no longer the case, but there GPIO structure definitions for example conflicts with the MP code definitions. I am not yet ...

I managed to get the ChibiOS as a library that links from the MP Makefile in stmhal. I figured since the main.c is in MP then better to make ChibiOS as a library. I got to a point where everything builds cleanly but could not get the ChibiOS to initialize the hardware correctly, with MP it is very d...

Disabling interrupts is not a big problem due to the fact that the duration is less than 10usec.
Assembly is the most optimal but no longer portable.

The SPI pin I need is already in use on the board, but thank you for the idea, a good one.
I will have to bit bang it in C then.
Is there a usec delay routine within the MP C code?

Interesting, I think your implementation could work.
I am using the AD8555 chip and part of its configuration requires to have short pulses for 0 (50ns to 10usec), long pulses for 1 (longer than 10usec) with at least 10usec between pulses.
It may work but I have to see in more detail what you've done.
