STM32L4P5 PB9 pin states in reset

2023-09-27
Why does PB9 idle high in reset for the STM32L4P5?  At least I'd like to know this the next time I design a board, where I could find this reference.  Full part is STM32L4P5RET although I'm guessing its the same across multiple parts.

STM32L4 DFSDM clipping

2022-08-09
Any ideas why values would be non linear in the approximately the upper 1 to 2 bits?For the setup below, it is linear to between -17000 to +14000. Doubling the + output only yields around +18000. These are raw values. This really acts like an overflo...

STM32L4R9 OSPI auto polling won't stop

2022-08-02
I'm using a STM32L4R9 with a W25G128, using non HAL code. The problem I'm seeing is that auto polling isn't stopped on match per logic analyzer. I have this set up to auto poll for write complete, register 0x05 busy bit 1. The match happens, I clear ...

CMSIS RTOS optional

2022-07-29
Why in particular has the CMSIS freertos wrapper been chosen as the only option for the cubeMX ecosystem? Has there been any consideration to add a raw FreeRTOS API option to cubeMX?For an example of what seems iffy, see osThreadNew in cmsis_os2.c w...
