Is it OK to call one of the app()->gotoXYZScreenoTransition() functions from inside the Model tick()?The reason I'm asking is that I just got a weird exception on this code that is inside Model tick():case (newData){ if (modelListener != 0) { ...

I'm porting a QSPI bootloader over from a design that 1 flash chip to 2 flash chips in parallel (10 bit mode, common CS). I am not sure how the addressing works now that there are 2 chips in parallel. I feel like the only thing STM32 says on the ma...

I have some re-used and portable code that uses <assert.h> and assert().Is there a way I can easily map assert() to the assert_param() used by CubeMX?Seems so simple but it is giving me a hard time, and I don't see anything available online about thi...

This is weird. Also it was working at one point and stopped working, can't track down the code change that broke this. So, I use HAL_UART_Receive_DMA() to start a DMA RX. I can use _HAL_DMA_GET_COUNTER() to check how many characters have been recei...

Thanks for the excellent writeup.So if something is at address at 0x1000 on the STM32, I should pass 0x500 to the QSPI command?For addressing, do I have to do that division manually or does the QSPI interface already do that for me if I'm in dual por...

Never-mind - I found a stupid simple solution:Put my own assert.h in the include path.
