Resolved! USBPD EPR mode

I have tried setup STM32G071 Sink port and connected with Apple 140w. I want to request 140W but it's seem STM32 not yet supported EPR mode in PD core. Do you have any examples for EPR in STM32?

Hi Sir/Madam,I want to implement a vibration detector using stm32f401vc discovery board which mainly consists of LSM303dlhc mems accelerometer sensor.The problem here is that when I am extracting the data from the sensor ,mostly the data is fluctuati...

I2C Slave Address Set Problem

I'm trying to read data from my I2C sensor, the MLX90614 sensor, using a STM32F411CEU6. When I examined the MLX90614 datasheet, I saw that the I2C clock speed should be a maximum of 100kHz and I configured the clock accordingly. However, after the st...
