Just hought i'd share JUCE running on raspberry with a 2.2 inch TFT display using SPI and a fbdev driver designed for those displays. This is a start of a monitoring solution for my fathers house, it has no electricity and is using solar panels + a Morningstart TriStart solar converter. This will read data from it using MODBUS and also monitor environmental data + power consumption data, all this will be logged and displayed on this tiny screen, power usgae is important.
Anyway it works and might be useful for someone.
