Resolved! How can i write on flash on STM32 MCU family?
I'm totally new on stm32 mcu's. i was working on a project and i want to update the MCU(The previous MCU was AVR) and i want to encode and decode base64 using Stm32CubeIDE(HAL Driver), so i decide to port my arduino library. The library is attached, ...
STM32G030 PGERR writing double word after programming from PEMicro Cyclone?
I have a strange issue with a STM32G030 and Flash writes. I am trying to change a 64-bit (double word) value from erased 0xFFFFFFFFFFFFFFFF to 0xFFFFFFFFFFFFFF00.I have three scenarions:Bootloader app erases and writes application imageSegger J-Link ...
Resolved! Multi Channel ADC + DMA on STM32F723. Conversion of one channel affects other channels
Hello ST Community,as part of a project I want to perform an AD conversion (ADC1 + DMA) of 4 channels at a sampling frequency of 5.5kHz. For this I have configured a timer which determines the sampling frequency and the data is stored on a MicroSD ca...
Resolved! Problem reading Flash Memory
Hello guys,I am working with a STM32L071CB MCU.Currently I am trying to backup GPS data to internal memory flash when there is not LTE connection to send later when the LTE service is restored.Writing data to memory has been done right. I am having p...
Pixel clock on STM32H7B3I-DK evaluation board
Hello,I am connecting a display to the evaluation board STM32H7B3I-DK. Increasing the clock frequency to 50 MHz this degrades so much that it cannot be usable. What settings need to be made to have a usable clock? Please, view the last screenshot of ...
Resolved! Information about internal flash memory of STM32L4R9
Hi,I'm working on a project where I'm supposed to save data that I collect from the XXXX accellerometer and then process it by performing an fft.I'm working on a project where I'm supposed to save data that I collect from the IIS3DWB accellerometer a...
ADC-SPI compatiable how to give the clk pulses?
Hello,I am working on stm32h7 series, I have to configure ADS7046IC which is ADC-spi comaptible.For communication purpose I need to give 15clk cycle. I set the SPI 50MHZ.How I can give 15sclk to it? Can u hepl me
How do I initilize two QSPI flash chips but only place one in Memory Mapped Mode?
I'm working on a system that requires the ability to do an Over The Air (OTA) upgrade. It's on a TouchGFX project, and the MCU is a 64K internal flash so the project exists on the QSPI flash in Memory Mapped Mode (MMM). I learned MMM is read only, ...
Resolved! Frequency is slightly shifted with microphone SPH0641 and DFSDM
Hello STM32-Community,I'm currently using the SPH0641 Microphone alongside DFSDM. My DFSDM settings are:Sinc filter: Sinc 3 FilterIOSR: 8Divider = 79FOSR = 37with a clock frequency of 48 MHz and as a clocksource for DFSDM I've a sample rate of about ...
