Busy bus after I2C reading?
2018-08-01
Hello, I try to interface with mlx90640 sensor via I2C. The MCU is STM32F401REAfter reading the bus stays busy. I use LL functions:int MLX90640_I2CRead(uint8_t slave_address, uint16_t start_address, uint16_t numb_words, uint16_t *data) { uint16_...

I solved the problem:put NACK and STOP generating after reading.uint16_t MLX90640_I2CReadWord(uint8_t slave_address, uint16_t start_address) { uint16_t puff; volatile uint8_t reg_m,reg_l,dat_m,dat_l; reg_m = (uint8_t) ((start_address & 0xFF00)...
