The Factory | Programming An I2C Responder Device
Let's program a proof-of-concept I2C responder device. In this episode of The Factory we've selected a microcontroller for our PiicoDev family and get it working as an I2C receiver to blink some WS2812B leds. We'll take a look at the proof of concept from both ends: I2C Host (Raspberry Pi Pico + MicroPython) to Receiver (ATtiny + Arduino C).
We also brush against the parametric search that found the device, and have a bit of a winge about the global silicone shortage.
