I have a Raspberry PI 3B which I've managed to get working with LINX on Community Edition 2022 Q3. I'm able to control gpio fine. I'm now trying to see if I can get a 20x2 LCD with I2C adapter board on the back. I know that the PI can see the I2C device via 'i2cdetect -y 1' returning a device on address 0x27. I'm trying to understand how to use the hobbyist I2C library. I've found the following example
Ignore my above question at this stage. I misunderstood something I was reading about the I2C interface on the example I pointed to. I need to try and locate what the actual commands are that I need to send over the communications. Reading up on that at the moment.
