I am trying to reconfigure DMA without losing samples and without stopping the ADC, which is triggered using timer (relatively rarely), so my plan was to look whether both the ADC and DMA are idle and quickly reconfigure DMA before ADC even starts to...
Hi everyone,Something weird happened while I was uploading to my board. The upload crashed half way through and now the USB STLink interface isn't recognized. I think I should be able to upload a working ELF file in UART mode, but to do that I need t...
Hi, I am using an STM32F429 to calculate the pulse times from an an IR receiver. The IR receiver outputs a signal that follows the NEC Protocol, which is defined here: https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+ProtocolThe pro...
I am new to BLE development and hence i am looking for a developers guide for using BLE on b-l475e-iot01a discovery board.-Thanks in advance.
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...
