Converting the code to use SFE BME280 code was easy. It is the Server and WiFi AP. On the MicroMod I have an ESP32 client. Converting the code from the Adafruit Micro OLED to HyperDisplay took time but it works full screen.
I also got it to work split screen but I do not know how to blank just one window. I tried to refill the window (myTFT.fillWindow();) like I did at the creation of the window but it turns black and the program stops.
As all I really need is to blank out the old values I tried printing blank spaces but that didn't do anything.
So is there any way to clear just one window?
ps I figured out how to use #define to create colors (I have a file converted from an Org file of several hundred color names and numbers). I have also figured out an easy way to print on the lines I want with the stock font.
