The board is originally a extension for arduino UNO, and I’m using STM32F446RE which also support arduino UNO expansion connector. Takes advantage of burst read and write cycles where possible. Here is the i2c2 initialization: void i2c2InitSlave(void) { I2C_DeInit(I2C2);. Product forums.
In I2C, the START condition requires a High to Low transition, if you then send a dummy address 0, a NACK will be generated (or rather the lack of any response will be interpreted as a NACK). (Image source: STM32F407 Reference Manual RM0090, Section 27. What I do is: I initialize sensor using poll method and it works fine. The problem is that while your line of . Example: Successfully tested on: Address register: Config register: Pins configuration: For using printf with float should be add flag -u _printf_float in C compiler HAL_I2C_Mem_Write() and HAL_I2C_Mem_Read() are also available for reading and writing to a certain memory location.
