As far as I can tell I've set up the PL correctly, enabling I2C 0 and connecting it to pins 50 and 51. Check that all FIFOs are empty and that the bus is not busy by reading the SR. Write 0x___ to the TX_FIFO (set the start bit, the device address, write access). For an AXI IIC configured with an AXI Interconnect Clock of 25MHz and a SCL configured with 100KHz with no-inertial delays, make the following changes: (The following parameters will have a default value of 122), Product updates, events, and resources in your inbox.
