Hi, I am using STM32F407VET6 MCU and trying to receive data using LL API LL_USART_ReceiveData8 over USART configured as modbus. I confirmed USART transmit (LL_USART_TransmitData8) is successful through an modbus APP, on rx side of the other devi...
I am using STM32H753ZI for my project. My use case is I want to detect brown out reset after brownout occurs and system restarts.I am checking brownout reset flag using if (__HAL_RCC_GET_FLAG(RCC_FLAG_BORRST). My query is this flag is shared/common b...
Hi,I am using STM32H743II microcontroller. In which communicating with external SRAM with FMC. It is working fine.I need to communicate with the touch LCD IC via I2C. There is no problem in communication when FMC is not active. I am reading the touc...
I need to write firmware for STM32H7xx to interact with an SPI flash memory chip. (STM32 master, 8-bit, full-duplex polling, no CRC and application controlled #CS.) I am using STM32CubeIDE 1.14.0 and used the device configuration tool to produce my S...
Here's how I implemented a custom bootloader using the STM32L475. I thought I would share since I have seen so many posts from people having issues invoking their application from their bootloader.I attempted to post this as an idea in the knowledg...
I need to debug an application code which is not on the default flash address (0x8000000) but it is at 0x8008000. I just changed the flash origin address to that value. When the execution reaches the CAN initialization part, the program counter goes ...
I want to configure the BLE of STM32 BL475E IoT-01A so that it could send and receive data via bluetooth from another Nucleo board.I couldn't able to find any proper resources related to this board.If it is there,kindly share the link
I was doing some tests on a NUCLEO-G071RB and I found out that the ADC has always some sort of offset in its digital output. I measure the tension on the MCU's pin and it's zero volts, but when I read the ADC the output is not zero. It can be 26-27 d...

I want to communicate with STM32f427 processor and 3 sensors via SPI. I want to use only SPI1 line. I need 3 chip select pins. There are 2 SPI1_NSS pins on the datasheet of the processor. What can I use as 3 CS pins? Is any GPIO pin suitable?
