I got this working, then it stopped working.I finally figured out after about 3 hours what is wrong.Situation. I am making a "Serial tap" for debugging. The STM32F411CE on the Black Pill board. 2xUSARTs Rx only and the CDC Virtual COM port device ...
I am not new to working with STM32 MCUs but this is a one-of-one.I have checked the baud rate to 115200 with 8E1, the serial com port driver is showing up on my computer and when I measure the USART-TX pin using an oscilloscope it is showing a signal...
Hello all，I am using the ADC on my STM32L431 with both DMA and interruption. Everything works fine, except that the ISR is often entered with none of the enabled interrupt flag being set.Initial code:void ADC1_IRQHandler() { if(LL_ADC_IsActiveF...
For example:#include <iostream>using namespace std;intmain(){ cout << "Hello Arm World!" << endl; return 0;}Can u give detailed info step by step?..
Hello,Are there any statistics on the probability of bit flips for the RAM on stm32f0x family? Are there any dependencies based on factors such age of the micro or temperature?
Hi. When debugging stm32l476rgt6 on NUCLEO-64 __WFI instruction has no effect.My question is simple: is it possible to enter stop mode while debugging? I know that it is possible to stop dbg clock during clear DBG_STOP bit. But after awake debugger d...
Hello,I want to test some code (including the exception handler for parity error) that kicks in when a parity error gets detected by the micro. But how can I induce a parity error?The processor is stm32f0x8.
hello everyone,i work on stm32g071 to build a application , but i configure the PA9 for uart TX and the PA8 for the normal input that pull up by 3.3v. When start send data by the PA9 , PA8 is disturbed。But PA9 is not configured, the PA8 level is norm...
