Now it's time to delve deeper into the state machine I'm using to control my I2C interface.
The three states associated with bi-directional "inout" pins can cause confusion for the unwary.
It's time to jump into unexplored territory -- the state machine that will control Duane Benson's I2C interface.
We're now ready for the I2C master to transmit a command set to a remote device.
Duane Benson has his SPI interface working. At some point, he'll want to rewrite the Verilog code, but first he wants to get the I2C interface up and running.
