For 3 days I have been increasing with the problem. I explain what's going on. I am trying to read using stm32f103 the width of the PWM pulses coming from the 4 channels of the RC receiver. I configured external EXTI interrupts, on 4 channels, edge t...
Try to use STM32G0 LQFP32 MCU do accuracy frequency measurement, but there is no HSE crystal interface, so internal HSI RC will be for system clock, the accuracy of the system clock will affect the frequency, how accuracy is internal HSI RC clock
Hello, i've got trouble with receiving SPI in interrupt.Im running 2 SPI's on STM32F103RCT6; first is transmit only master, second is receive only slave, bus speed is 2MHz on both. SYSCLK is 64MHz.Transmitting works great (blocking mode), but HAL_SPI...
I want to disassemble the ADC function and BLE data transmission asynchronously.So, I want to program the microcontroller using multi-thread.When I coded BLE, It look already used multi-thread but I couldn't understand it exactly.Is there any example...
Hello,I have a project working on the F303-re Nucleo board. I want to run it now on the F303-ze Nucleo board. Apparently virtual com port doesn't work the same on the ZE as it does on the RE. I can take a new RE board, copy the binary file to th...
Our custom board is using the stm32u585. The MCU is the master, communicating with a accelerometer through SPI port 3.When reading the data from the accelerometer, using HAL_SPI_Receive_IT or HAL_SPI_Receive_DMA, the SPI 3 interrupt is constantly gen...
Below I am mentioned the code kindly go through it: if(PushButtonFlag == 1) { HAL_UART_Transmit_IT(&huart1, PushButtonPrint0, sizeof(PushButtonPrint0)); //Open file for writing (Create) if(f_open(&SDFile, "STM32.TXT", FA_CREATE_ALWAYS | FA_...
I ran stm32 with cubemx and iar to execute the project, but I have to remove the st-link line and execute itIf I take out the line, the project can't be executed, so how can I only connect the board and power to run the project?download active applic...
I struggled with the CMPM interrupt and made a small test programm to reproduce the bug.To see whats going on I use an oscilloscope with 2 GPIO pins called A and B.Pseudo Code:LPTIM_IRQHandler() { setGpioA; clearFlag_CMPM; resetGpioA; } main()...
I am trying to setup UART on an STM32L072CZTX. In the ioc file I have setup the pins, RX is set to AF4 pullup, and TX is AF4 nopull. The interrupt is set to 0 and enabled. I have redefined the RxCpltCallback in the main and have events occur in there...
