There is a function called HardFault_Handler in the STM32 MCUs (full code below). This function I usually work with when debugging but am unsure how to use this for handling error. What is the correct protocol to handle errors in this function? If a ...
Executing this code sequence on a STM32H743ZI or STM32H743IIRCC->AHB3ENR |= RCC_AHB3ENR_QSPIEN; QUADSPI->CR = QUADSPI_CR_EN; QUADSPI->CCR = QUADSPI_CCR_FMODE_0 | QUADSPI_CCR_IMODE_0; QUADSPI->DR;i.e. indirect read with only an instruction phase, t...
We are using an STM32H743ZI in our application and just got the first prototypes. I was using a current limited power supply for initial test to protect the circuitry, however, something has caused two micros to fail so far after only a few power on ...
STM32F302K8 here. According to the manual, there is a flag in the ISR to see if the bus is busy, but it does not generate an interrupt when cleared. Also the STOP condition says it is only generated while you are the master and generate it, or are ...
Appending more details here,Configured TIM2 as counter. Below is the TIM2_INit code,static void MX_TIM2_Init(void){ TIM_SlaveConfigTypeDef sSlaveConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; htim2.Instance = TIM2; htim2.Init.Prescaler = ...
Hello,For communicating with a sensor I need to send 32 bits as a clock for my sensor. As you can see in the 8-bit data transmission an interruption occurs during sending 4 bytes which is unpleasant for my communication. I wrote a Software SPI (bit-b...
Hello, I am uing STM32F103 MCU and I am having a small problem with the ADC. There is a 250 mV difference between the real voltage value on a pin and the value ADC gives me. When I measure the voltage on a pin it is 900 mV. But when I print out the A...
Hi all,I'm developing a low power sensor node using the Nucleo STM32L432KC development board, and I was wondering what the lowest power mode is from which the device can wake up and just continue operation from the next line of code after the sleep c...
