How to run NUCLEO-F031K6 on 3.3v supply

I have a working project* based on the STM32f031k6 (NUCLEO-F031K6). I have been running it successfully from a 4.8V Ni-Mh battery connected to the VIN pin for some time.Now, I want to modify the design to run from 3.3V. I have disconnected the VIN co...

Can I2C master support both high speed mode and fast mode?

We use stm32g474re in our project. The i2c devices used in our board have two types, one support high-speed mode while the others doesnot. Currently, i set the i2c master with fast mode(400K). Is it possible to set i2c master with high-speed mode and...

How to control 6 rotary encoders with single MCU

Hello All!I have found that I can read encoder information with HAL functions e. q.HAL_TIM_Encoder_StartBut only few timers have encoder modeIf I need to control 6 encoders I have found STM32F103 RF MCU with enough timers.Is there another solution to...

Communicate via UART Using SensorTile with Nucleo Board ST-Link

I'm trying out some neural network programming on the SensorTile with the STEVAL-STLCX01V1 expansion cradle and have been having some issues printing my results via the serial port (just a simple string containing a number). I have managed to set up ...
