How to config track clock on NUCLEO-H563ZI
I am using the MDK-ARM tool to develop our application.When I enable the "Trace Exceptions" function to trace all exceptions, it always show "No synchronization" in red below. And no exception can be seen from the table.I also uploaded the trace cloc...
Why should in 'G4 PB8/BOOT0 be set to non-Analog?
In 'G4 Datasheets and RM, the following remark can be read:It is recommended to set PB8 to a different mode than the analog one to limit theconsumption that would occur if the pin is left unconnected.This must be important, as it's at both in DS and ...

STM32F4 sometimes not booting correctly
Hello,I have a PCB that I have installed an STM32f407 or STM32f427. The PCB has CAN peripherals, serial peripherals, a status LED, a reset button and other peripherals.I have seen that on startup sometimes the STM32F4 doesn't startup correctly. When ...
Resolved! Irregular adc conversions triggered / synchronized by timer
Hi there!I'm working with a nucleo144-STM32F767zi and facing a problem with irregular ADC conversions (HAL_ADC_Start_IT) which are triggered by a eg. 50 kHz timer update event (every 20 us TIM1 fires an update event)ADC Clock prescaler seems to be PC...
Resolved! Decoding the STM32H563 datasheet (RM0481 rev 1)
The MCU is great, but the datasheet (in particular the SPI section) is very hard to read. Whatever the original language was, it wasn't English, and I guess Google translate has been involved. I've added an example below, and hope for ST to update th...
