For the past few days I've been trying to make the ESP and the LED Display work together but with no luck.
I've used a ESP-Wroom-32 DEVIKITV1: https://i.postimg.cc/mg8nNsDD/20190403-121636.jpg
I'm using a 64x32 SMD 2727 P5 LED Display.
I've used this library: https://github.com/NeoCat/ESP32-P3RGB64x32MatrixPanel
This is the schematic of the board: https://i.postimg.cc/PxXHWhh6/Schematic ... 160858.png
VCC = 5V;
These are the specs of my power supply: https://i.postimg.cc/prt2vnW7/20190401-145102.jpg
I tried uploading the example codes from the aforementioned library but I noticed that I couldn't upload any code to the ESP32, because the BOOT button seemed like it did't work, so I took ESP off the board and uploaded the code then put it back in and noticed a bizarre behavior:
If the ESP32 is half-way inside (like this), the screen is white if I insert it all the way it get's red.
If I hit reset on the ESP, the display will be off, and the Serial Monitor will output:
Code: Select all
rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371

Since then the ESP32 is not responding. I've ordered 2 more modules.
What do you think the problems were ? I think it should've worked, yet it didn't and it may have burned the ESP.
Since I will try this again when the new ESP arrives, I don't want to burn it right away.
Thank you !
