IIC_B peripheral-mode demo. The chip listens at a fixed 7-bit I2C address on SDA/SCL and toggles LED1 on every successful transaction. There is no UART output – LED1 is the only observable signal, which also means a UART scrape can never gate this app.
An external I2C controller on the bus. The chip is in target mode and waits for a controller to initiate transactions; the bench Pi has I2C controller capability on its own header, but there is no jumper wiring to the EVM's IIC_B pins today. Closing the gap needs both that wiring and a probe-able transfer counter in src/main.c, since the LED alone gives an automated rig nothing to read.
