Re: No one even mentioned the new Raspberry Pi Pico?

I think the strength of Pico is the programmable IO, which is very powerful, can be programmed in different modes, but it requires some programming knowledge. I haven't seen before such a solution.

Re: Examples

You have to first select the correct board ("Generic STM32F103C8 series") and then you will have a long list of examples.

Re: No one even mentioned the new Raspberry Pi Pico?

I didn't dig to deep, but has the Pico a DCMI interface?
What I can see is that Pico has great PIO which is best for WS2812 users.
Beside that and the second core I think a F4 can do all the rest as well, eventually faster (up to 180 MHz).
But it is certainly very interesting, I will probably buy one.

Re: SPI/DMA Filtering frames on the fly

I think you should try

Code: Select all

spi_rx_dma_disable()
, this should avoid any further data reception.

Re: [SOLVED] Maple_Upload.bat : EXCEPTION_ACCESS_VIOLATION

I also use a major rework of the repo, but it still updates newest commits because I forked the main repo.
Unsure why the fix works for you without updating the platform.txt, that is not for linux, but for windows.

Re: [SOLVED] Maple_Upload.bat : EXCEPTION_ACCESS_VIOLATION

Actually, this should have been fixed by this commit: https://github.com/rogerclarkmelbourne/ ... 6f538824d9
If you have already this fix, can you please post your complete error log?

Re: Interrupt FALLING not working as excepted

If you use mechanical switches /pushbuttons then the behavior is normal, becase they cause spuorious transitions low->high->low... when activating them.
You have to debounce those inputs.

Have you installed the drivers with admin priviledges?

I would try this one: https://www.st.com/en/development-tools ... 32080.html
Then restart the computer.

Re: Problem with Port

That is a clear sign that your driver is not installed or activated correctly.
Look for a "Unrecognized device" in your device manager in the case you get that message, then try to update that driver automatically.
