Looking for Examples. B-L475E-IOT01 or 02. Unable to init Temp Sensor on board

I'm looking for any examples that use the functions/methods/drivers found in the PDF: UM2298 User manual STM32Cube BSP drivers development guidelines . I've installed the Board Support Package in my project and it specifically includes the files: s...

I wrote a code to use can bus for stm32f103rct6. It doesn't work on stm32f103rct6 but work on stm32f103ret6. Why? Can you help me?

How to calibrate the ADC of a STM32F7?

I am currently using a STM32F767ZI. As the function "HAL_ADCEx_Calibration_Start" is not possible for a STM32F7, is there any other funtion or method (e.g. calibrating manually) for an ADC calibration to increase its accurancy?Thanks for any help.

How can I make a STM32H7A3 UART work in loopback mode?

I have some simple polling UART code that works fine when connected to a GPS receiver. I send a command and get a response back. Now I'm trying something new and it would be convenient to work with RX and TX looped back (connected together) so I rece...

NUCLEO-F410RB Error Multiple errors reported.\ Failed to execute MI command: - var-create -*

Hi, I was developing I2C code on the NUCLEO-F410RB to work with the BH1750 light sensor from adafruit when I came across multiple errors in debug mode. The errors can be seen in the "ErrorMessages" attached photo.The "result" mentioned in the error m...

EMW3080 not working properly

Hi,I flashed an EMW3080B module with this firmware ST-EMW3080B_V2.1.11_SPI.ALL from this location on another board not B-U585I-IOT02A. It is connectet to SPI from STM32. Problem is next: when MCU set pin 11(CHIP_EN) from EMW3080B to HIGH to enable mo...

Nucleo F401RE registering as NOD_F401RE instead of NODE_F401RE

I have software that runs on the Nucleo F401RE, and I install it by searching for the NODE_F401RE 'disk drive'. But recently I've noticed that some Nucleo boards register as NOD_F401RE (no E) drives. And of course this makes a mess of my download. Ca...
