Resolved! I want the code is copied from Flash to RAM after poweron,then the code is running at RAM.
I've changed the .ld file for STM32G474 generated by STM32CUBEIDE.The part of old .ld file is like this,I added ">RAM AT" at the last line like this,But when I'm debugging,the code is running into the HardFault Handler.I want to know if something els...
Please give me some example for RS485 with automatic hardware flow control when interfacing with Energymeter...Tried a lot but not able to receive anything from energymeter.
I have connected my RS485 automatic hardware flow control with energymeter and with the help of that, tried to transmit the query 01 04 00 21 00 02 (forf voltage) along with CRC check ....uint16_t ModRtu_CRC(uint8_t buf[8], int len){ uint16_t crc = 0...
SPI shifted bytes problem
Hi all, I'm working with STM32F407VG-Discovery kit and I'm trying to create an application for exchange data via SPI with an ESP32 controller.I'm facing some problems with the synchronization. The STM32 acts as slave in mode 0. ESP32 controller sends...

SPI data Issue with SPI_DATASIZE_8BIT
Hi,I'm facing an issue after configuring the SPI1 of STM32G491REI6 MCU using STm32CubeMX for SPI_DATASIZE_8BIT. I have captured the signals on the Oscilloscope after Transmitting the followed three-byte (0x03, 0x00, 0x50) from master(MCU) to slave. y...
UART RX does not work after changing clock from HSI to MSI
MCU - STM32L431RC; HAL drivers ver 1.13.After switching clock from HSI to MSI 16 -> 32 MHz,CubeMX generated system Clock setup does not work.When trying to send data to STM constantly getting "Noise error" and rarely 1st byte is received via ISR. TX ...
Reading more than 8 ADC inputs using interrupts on G070 MCU
Hello, I'm trying to read 9 ADC inputs on the G070 MCU using the interrupt method. Unfortunately, under the number of conversions setting I can only do 8 conversions. Is there a way around this? hadc.Instance = ADC1; hadc.Init.ClockPrescaler = AD...
Resolved! I want to use STM32G series for SDIO, so that I can use eMMC card. we can not use other stm32 controller.
Dear Sir,we are using STM32G series controller in our project but the problem is that we are also using eMMC card with 4GB which work on SDIO connectivity.could you plese share me which STM32g series will be suitable for it.Thank you
