Any Documentation on the ESP-WROVER-KIT LCD
Is there documentation on the LCD so I can find a support library in the Arduino IDE?
Re: Any Documentation on the ESP-WROVER-KIT LCD
Hi Reefhermit,
There isn't a lot of documentation for the display yet, but the LCD controller is an ILI9341 controller which uses the SPI bus.
You can check the ESP-WROVER-KIT schematic linked here to see the pin connections between the ESP32 and the LCD controller.
If using Arduino, there are some ILI9341 libraries which can be used with ESP32. They need to be configured to use the pins shown on the schematic.
For ESP-IDF, a library for writing to the display is currently in code review and testing. The proof of concept nesemu code also has a driver for the ILI9341 on this board.

Also, the example for the SPI driver in esp-idf basically is a low-level driver for that display. You may want to use that instead of the NES driver; it should be slightly less CPU-intensive.

Thanks for the prompt reply . . . . unfortunately the ILI9341 drivers do not complile in the Arduino IDE

Hu,
I use the driver from olikraus. Tutorial with a fix: https://www.youtube.com/watch?v=smk8BRFwcs8

See my repo for an SDK native demo as well as my new port of a comprehensive LCD demo using the core Adafruit ILI9341 and GFX graphics libraries that works with Arduino-ESP32:
https://github.com/MartyMacGyver/ESP32_Adafruit_ILI9341
Note: tested on the ESP-WROVER_KIT using the current commits in the esp-idf, arduino-esp32, and Adafruit repos, with the latest Arduino 1.8.1.

If you're talking about the Adafruit library, the stable version (in Arduino Library manager) doesn't support ESP32 yet (assumes AVR processor) but the development version in their github repository should work.Reefhermit wrote:Thanks for the prompt reply . . . . unfortunately the ILI9341 drivers do not complile in the Arduino IDE
EDIT: I hadn't read ahead to Marty's post, that sounds like a good option as well!
