"WebbYou said that you send the slave address and the address in the eeprom using DMA so the ADDR flag will not be reset -> that is why the line remains low (stretched because ADDR is set) and consequently you will not be able to generate a START. The DMA requests (when enabled) are generated only for data transfer. " - I2c_direction_receiver

WebbFör 1 dag sedan · Summary. I2C offers a good middle-ground between UART and SPI, offering improved data throughput over UART and eliminating the need for separate CS lines for every device, as is the case with SPI. Instead, I2C facilitates a shared clock signal generated by the active controller. In addition to the clock line, the devices only need a … Webb1. The receiver is unable to receive or transmit because it is performing some real-time function and is not ready to start communication with the master. 2. During the transfer, the receiver gets data or commands that it does not understand. 3. During the transfer, the receiver cannot receive any more data bytes. 4.
