STM32F107 BKP

Please note that contrary to as listed in Atollic's SFR viewing tool during debug, the backup registers (BKP) start at 0x40006C04 not 0x40006C00 as convential wisdom would suggest.

Resolved! STM32F767 LSE oscillator not oscillating, why?

I've hung a 32.768kHz crystal (IQD) on to my STM32F767VGT6 with a pair of 10pF caps as per AN2867, but I'm not getting the LSE to oscillate. If I route the LSE to an MCO output I see random transitions, which explains why the RCC status bit shows it'...

STM32F100RBT6. I left HAL libraries behind and want to work writing straight to the registers but something is wrong and it does not work.

I want to blink a LED and I have written this code:#include "stm32f10x.h"int main(){ // initialize the clock for Port C RCC->APB2ENR |= (1<<4); // enable clock for GPIO C ( check it on memory and bus architecture) // set pin 9 of GPIOC ...

I have a question about P-NUCLEO-USB001.

What I want to implement is to control the role of the module between host and consumer, when modules are connected to each other. Is it possible with programming ?If impossible with this module, what module can I use to implement that task ? Thank y...

Resolved! Only 4 Bits for Interrupt priority (NVIC STM32H743) ?

Hi,the IPR bit assignment in 'PM0253 Rev 5 p.189' tells me that a number of bits [n-1:0] are read as zero and ignore writes.At this point n isn't 'n = m MOD 4'.Obviously n is 4 because i can write only the four upper bits and bits [3:0] stay at zero....
