Re: Configuring EXTI

Hi,

Look into the PAL driver (and demo), EXTI callbacks are handled there now.

Re: Mutithread variable share Topic is solved

I don't see enough code for an explanation. It is possible that thread is starving the others, there are no sleep functions called inside the loop.

Re: Mutithread variable share Topic is solved

Hi,

Make the variable "volatile" or the compiled will optimize it out.

Re: STM32G0xx

Hi,

G0 examples are in the "multi" projects, no standalone projects for newer platforms (going to remove gradually old ones too).

Re: Chibios Git

Hi,

Do you mean this one?

https://osdn.net/projects/chibios/downl ... 1.11.1.7z/

It works for me.

Edit: I missed the point about "when trying to push to Git"....

Re: STM32G474 shell over USB demo

It is working here, probably ACM0 is the ST-Link in your case, try ACM1.

Re: STM32G474 shell over USB demo

Hi, If it is a Linux PC nothing is required, it should just work. Is the USB connector attached correctly to the board? It is also possible that your terminal emulation program is sending some unsupported Ep0 command causing the driver to stall. If it is an USB3 try an USB2 port, just in case. Giova...

Re: SPI Hal - Waiting to MISO line to be released

Waiting for a rising edge is asynchronous, it triggers a callback. See PAL callbacks.

Re: SPI Hal - Waiting to MISO line to be released

Hi,

I think you could use GPIO (PAL driver) and poll for completion or to wait for a rising edge.

You could also keep doing spiReceive() until you get an 0xFF if the extra clocks are tolerated by the ADC.
