A while ago I received an STM32 discoveryboard as a gift, after I told some people on a fair that I'm a software engineer. Because I'm allready experienced in C/C++ but new to embedded software engineering, I ordered a course. Now I get stuck on the ...
during debugging i came to notice that after PCDinit() ,few instructions contating read and write on rc522, is receivng correct data through spi but after that it always read zero. same problem had been arrived earlier too but it started working on...
I have been banging my head against the wall for days on this one. I'm using STM32CubeIDE 1.1.0. I create a simple project with a SPI interface and DMA. I'm attaching the full project. I call one function: MX_GPIO_Init(); MX_USART2_UART_Init(); ...
#include "stm32f4xx.h" // Device header // Trying to use the General Purpose Timer (TIM2) to create a 1 second delay // Board External Crystal 8.0 MHz // Port A Pin 0 Output // The program should output a high on GPIOA Pin 0 and ...
Hi I cant seam to get the F7 to transmit the TDM output in the correct timingI have SAI Block A1 as the Slave Mode RX and B1 as the SAI TDM Tx that is sync to Block A1The Format is 8 x 32Bit Slots TDM Slave mode to a DSP Via DMA Circular bufferWhat ...
We're porting some existing working code to the STM32G031J6M6. On pin 5, we are using TIM3CH3, and passing high time data from an 8 bit array to the 16 bit CCR3 register, and the waveform is as expected - correct.On pin 4, we are using TIM2CH1, and p...
Posted on October 14, 2015 at 00:22 Hello, I am trying to get my STM32l053 to wake up from stop mode using the RTC wake up timer (using CubeMX). I've done some testing and found that stop mode works, and I can wake it back up using a but...
Hi, I'm just a Firmware Engineerrecently, i 've designed the mcu circuits.i 've checked the stm32f072 DISCOVERY Board few days ago.in the board block, it embedded SWD (2-Wire for J-TAG)-----------------------------------------------------------------...
my device was working properly. but when i enabled lvl 1 RDP protection..all peripheral device connected was still working correctly. but the moment i changed the optional byte to level 0 again n erase the whole flash and reprogrammed it again wi...
HI, i am using STM32L476RG and need to acquire data at 1.5MSPS in a buffer, size 2048. Everything is working however i cant see how to get an interrupt once the buffer is filled.I thought the TC flag could be used but when i check in the DMA interrup...
