While I have found some conflicting advice…Adafruit states “ I2C interface, 0x5A is the fixed 7-bit address.” The Adafruit IR Temperature Sensor is a good example. However, some devices appear to be more difficult than others as to setting the address. The solution to issue 2 is to be able to set the address on each one of your I2C devices. All devices on a Wire/Wire1 interface needs to have its own address.There can only be two Wire interfaces, Wire and Wire1.One of the first issues, I needed to explore was to understand how to use the Pico’s 10 I2C interfaces, given the following issues with Arduino Wire: That said, with the Pico’s power, comes a bit of complexity. With the addition of the Arduino framework, it makes using the Pico a simple decision for a lot of Uno projects.
For only $4, you can buy a very powerful, very well documented and easily available microcontroller. The Pico is an incredible board, well worth using due to its outstanding price/performance ratio. I have been using the Arduino framework and legacy IDE ( 1.8.19, not the 2.0 version) to develop code on the Raspberry Pi Pico. Where I explore how to use the Pico’s abundance of I2C interfaces to create 2 separate I2C instances.
