I have compared the signals from 32-32 and 32-8, in the 32-8 the 'ACK' pulse remains high instead of being pulled low. I did use a logic analyzer and start condition is in fact not generated (line stays at logic 1) I implemented the following routine to restart the peripheral: In this Mode it is advised to use the following functions: (+) FlagStatus I2C_GetFlagStatus(I2C_TypeDef* I2Cx, uint32_t I2C_FLAG); (+) void I2C_ClearFlag(I2C_TypeDef* I2Cx, uint32_t I2C_FLAG); [. 1 Dec 6, 2022 · I am using the I2C code in STM32Cube_FW_F4_V1. Before you In the world of electronics and embedded systems, microcontroller development boards have become the cornerstone for both hobbyists and professionals. The I2C is a multi-master, multi-slave, synchronous, bidirectional, half-duplex serial communication bus. I suppose that in case of a real error, the transfer would be stucked later on due to the clock counter desynchronization between master and slave, so a SW timeout would occur. h. i2c-smbus handles specific protocol SMBus Alert.
