2.4" TFT Input and display carrier board with an ESP32 processor board
I can make several peripherals out on the QWIIC bus work and can make the push-button example code work. So I’m thinking that I’m loading libraries correctly, have the right board configuration, and everything is working. I just don’t see anything on the display when I try to run any of the “HyperDisplay 4DLCD-320240” example code options. The display backlight is on, but there is nothing on display. I’ve tried loading the code with a MicroSD card installed, and without a MicroSD card installed. (Do I have to pre-format the MicroSD card or something?) None of the tutorials mention anything about needing a MicroSD card to get the example code to work. What am I missing?
This is almost always an issue with the 3 prerequisite libraries needed to use hyperdisplay
https://learn.sparkfun.com/tutorials/sp … rogramming Be sure to grab all 3 mentioned here and re-try; any change?
So I went back and reloaded the three HyperDisplay libraries, and over-wrote the old ones. Same thing and no luck. I did open the serial monitor to see if anything was going on and I see sixteen copies of the attached image. Would it be safe to assume that the board keeps trying to reset itself whenever I successfully load a HyperDisplay example file? Maybe I have a hardware problem with just the display only? I also attached a copy of my Output. It says “Hard resetting via RTS pin…” and just finishes. Is that the proper way to see the output after loading one of the HyperDisplay examples?
Were any esp32 libraries installed before trying to use the micromod one? Sometimes arduino gets confused…I would start all the way over with a wipe https://support.arduino.cc/hc/en-us/art … rduino-IDE
note you must do the step deleting arduino15 leftovers files…then start all the way over - if it still doesn’t work, file for a return 
Wiped it all out, cleaned up everything, then reloaded. Same issues. I think I’m going to try to return the board somehow. Thanks for your input.
