I am brand new to Newhaven's products. I just received the NHD-FT81x-SHIELD and NHD-5.0-800480FT-CTXL-CTP, connected them to my Arduino Uno and tried to run the sample code from github: https://github.com/NewhavenDisplay/EVE2-TFT-Modules/tree/master/5.0in/_800x480/Capacitive
But when I upload any of these projects it results in a blank white screen on the HMI. Is there any simple step I might be missing or recommendations to troubleshoot this problem?
