Hello, i recently purchased the arlcd with the uno on the back. i am having trouble with it receiving any data and displaying it via the serial monitor. i connected a ds3231 rtc to it using i2c with no joy! installed 4.7k pullup resistors and still no joy! ran a i2c scan sketch to test if any thing could be found but still nothing. i set up a temp sensor into analog pin A1 and read from the serial monitor but still nothing.
i then repeated the above using a genuine uno and all worked find?
what do you think might be the problem with the arlcd? just like the idea of the touch screen for my projects.
i can upload the example sketches from the arlcd library no problem, all displays fine. just wont receive and data from useful sensors i want to use.
does firmware need updating? cant seem to download it, is this device still supported?
many thanks all help appreciated.
