Posted on July 11, 2016 at 17:27I'm working with STM32F070xBI need to configure GPIOs PA11 and PA12 to USB D+ and D- alternate function. According to datasheet it is listed as Additional functions (not Alternate) USB_DM and USB_DP. It is not clear h...

Issue getting all data over USART with LL API LL_USART_ReceiveData8

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...

Resolved! Brown Out Reset in STM32H753ZI

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...

I2C does not work when FMC is turned on

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...

Resolved! STM32H7xx SPI. Tutorial, documentation or example code needed.

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...

Custom bootloader on the STM32L4

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...

Resolved! STM32 goes outside of program code if CAN is enabled and the flash address in not the default

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 ...

Resorces regarding Configuration Of BLE of STM32 BL475E IoT-01A

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

Resolved! STM32G071RB 12BIT ADC provides a non-zero output even with a zero volt tension input

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...
