I have an ESP32-WROVER successfully driving a 64x64 outdoor LED module using SmartMatrix in Arduino IDE. I would like to achieve a 120 Hz frame refresh rate, so that I can use the default camera settings for the typical smartphone to photograph or video the display.
I’m aware of the minimum refresh rate and refresh rate settings; however, I don’t believe I can set the refresh rate at 120 Hz and actually GET that refresh rate, precisely. Am I correct, or am I just missing something that is easily tweaked?
This same question has possibly been asked in a variety of ways, but I was unable to find my answer.
Thanks for your help!
