I have timer 1 setup to PWM a wave form and timer 2 setup to PWM a different frequency wave form. I need to restart timer 2 when an output compare match (CNT = CCR) on timer 1 occurs. It appears that I can do this with master/slave configuration of...
I want to generate a ~200us pulse on the DAC (variable output) that occurs at 20Hz.The DAC itself is no problem, the 20Hz is done with a timer interrupt.What is the best way to implement the 200us timing? Preferably non-blocking, Another timer that s...
Hi,Is it possible to distinguish an STM32G0B1KBU6N from an STM32G0B1KBU6 based on the UID?Is it possible to read this UID in FW in order to recognize whether the correct controller is fitted or is this only possible via the SW interface?
Hi everyone. I am trying to communicate with a board called EVB-LAN9252-SPI via SPI, and I am only getting the datasheet-correct result for the first SPI request.If I send 0x03 and then 0x0050, I should get 0x92520001. Right now, I only get 0x9252000...
Hello everyoneIt's my first time messing around with STM32 microcontrollersA few days back I got a black pill (STM32F401CCU6 - https://robu.in/product/stm32f401ccu6-minimum-system-board-microcomputer-stm32-arm-core-board/) and an ST-Link V2. The blac...
I am using SPI4 PORTE pins 2,5 and 6. I have a 16 channel ADC hooked up to it. Everything functions as needed on the ADC including. Reset, Averaging setup, channels setup. I can see the MISO pin(Pin 5 PortE changes as the voltage changes. but 0 is re...
Hi. I am using the STM32H7S78-DK board.In STM32CubeIDE, I checked the example for jpeg_encodingFromXSPI_DMA. When the encoding is finished and the LD1 LED turns green, how can I retrieve the size of the encoded jpgBuffer as a variable?What I've tried...
I have designed a custom board using STM32H573IIT3Q MCU. when I connected it with st link, the st link not recognize it. After I check the voltage on power pin, all the power pin is normal except the VCAP pin (not outputing voltage). According to the...
Hi, I have an STM32H723ZGT which I am having problems with hanging at boot.When debugging, it is stuck at /* Wait till LSE is ready */ while(LL_RCC_LSE_IsReady() != 1) { }in main.c I currently have LSE disabled and RTC clock set to LSI, but...
I am using STM32H723VG and I want to implement bootloader for firmware update. I want to enter STM32 bootloader to flash data through USB DFU inside firmware: #define BOOTLOADER_ADDRESS_START 0x1FF09800 void Bootloader_JumpToBootloader() { __d...
