I have the low power timer LPTIM1 working on a STM32H7A3 but the way I have to clear the IRQs is a little confusing. Here's my IRQHandler:void LPTIM1_IRQHandler(void) { //Disable LPTIM1 CLEAR_BIT(LPTIM1->CR, 0x01); //Clear IRQs LL_LPTIM_ClearFl...
I am trying to write code for a simple transmit and receive in FDCAN (Classic Mode) in external loopback mode, but I have been unsuccessful in doing so. I don't even know where I am going wrong and am looking for help as my last resort. I have tried...
hi, i m using STM32H7 and have running SPI using interrupt transmittng and receiving from external ADC, now i m contemplating using DMA for SPI transmit and receive, but was not able to get any data reponse from the ADC. could anyone kindly advise an...
Hi Guys I'm facing one problem in GPO side .i have try to read the input pin PA_3 and PA_2 that time i'm facing one issue .what i'm do try to read the switch using PA_3 and PA_2 Software side i have write pull down when i'm press the switch one PA_3 ...
Hello, In my motor control project, I'm reading potentiometer value and set it as a duty cycle value. Initially I'm using "htim1.Instance->CCR1 = 50;" this function for pwm. but this is not giving correct phase voltage. Can anyone please tell me wh...
I use STM32F407 Discovery board to generate analog signals using DAC with DMA transfer. The goal is to use both DAC channels to have two signals generated simultaneously. However, I cannot enable the DMA request for the second channel. After analyzin...
Hi, I am MURALI SELVAM I need a reference schematic for STM32F103RCT6TR. Anybody with a reference schematic for STM32F103RCT6TR, Kindly share me thank you.
I have a few questions about the DFU mode on the STM32F723. My goal is to enable users to flash a binary file to the MCU via a USB connection. My implementation is that i placed a 22uF capacitor on the boot0 pin then tied another IO pin (EO) in this ...
After careful deliberation, I must choose between either the STM32H573xx or STM32MP151A/D type of MCU. The specific one will be selected later once the board design is more finalized.The board incorporates a cellular module crucial for its operation,...
Hi community, just a single question as confirm. I am working with stm32f429.From the schematic the hw engineer decided to use the following pin for spi purpose for communicating with an eeprom Can you confirm that i cannot use those pins for spi p...
