How to run esp32_3248s035c on arduino platform ?

[eagl1]

Hi,

I'm trying to compile and program this display on arduino ide.

I have the esp32_3248s035c 3.5" capacitive display.

Is there any source code that I can adapt for my programming ?

Hi Eagl1,

I haven't made any provisions for Arduino GUI bit think that zipping the library directory and defining the defines in the boards definition should do the trick...
I can however recommend switching to PlatformIO!

That's what I'm doing now, it fails to program the board. I think it's hardware issue because it didn't program on different methods.

I tried platformio, arduino ide and flash tool.

I switched to platformio and got it to work.

It didn't work previously, because I didn't installed it in the default install location. I should let the install procedure go as is especially with vs code.

Now it's working.

Also, these are the issues I found for this display to get it to work on Arduino platform:

//////////////////////////////////////////////////////////
// issues for SPI display in arduino ide 
// ESP32_3248S035
1. Not programming --> install CH340 2019 driver
2. Programming but no display data 
   --> erase all flash before sketch upload
   --> enable PSRAM --> not important

If you are prepared to move your platform, try the brilliant Annex32 Rapid Development System which will get your module working immediately but you will have to program in BASIC. Annex32 is only for ESP32 and ESP8266 boards but has a full implementation of BASIC. It also allows you to program the board remotely via WiFi after the initial download by USB.
