STM32H7 SPI communication issue: RxFIFO management
I've been struggling for quite a while now on my SPI setup.The setup is as follows:- SPI Slave is a Nucleo STM32H743 in simplex mode, clocks at maximum (sysclk 400MHz, hclck 200Mhz, APB clock 100MHz)- SPI master is another identical Nucleo in simplex...
Reading I2C bits with STM32F4Discovery
Hello. I have the following scheme for reading the output of humidity sensor that communicates via I2C:How would I execute this sequence with STM32CubeMX IDE and HAL libraries? The output of the sensor is as follows: All I have now is this code: uint...
Resolved! The SDIO_CK clock is unexpectedly stopping during an eMMC erase command. Why?
I'm trying to erase the entire eMMC chip using an STM32F405.I send CMD35+CMD36+CMD38 and get the expected R1 response from all 3 commands. After CMD38, the D0 line goes low to indicate the chip is busy erasing. About 1000 SDIO clocks after CMD38, the...
The purpose of DSP and MAC integrated to MCU, like 16 bits MCU ST10F276 and it's special applications.
ST10F276 ( 144 pins, 512 Byte Flash, 320K Byte Xflash) has integrated with DSP and MAC, what the purpose of it? any special application for such configuration? which STM 32 bits MCU have same construction? thanks.
Resolved! How to handle HardFault?
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 ...
Resolved! STM32H7 reading QUADSPI->DR freezes the MCU after QUADSPI->CCR = QUADSPI_CCR_FMODE_0 | QUADSPI_CCR_IMODE_0;
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...
STM32H7 failing (dying) if there is oscillation on the power supply.
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 ...
