ESP32 5" HMI Display and Arduino IDE
Hi there,
I'm trying to get the Elecrow 5" HMI display (version 2 with i2c socket) going using Squareline Studio and Arduino IDE. I've followed multiple tutorial and YouTube videos, however the board crashes when trying to initialise the display with tft.begin() which seems to be related to the SPI Pinout / driver.
I understanding that the Arduino TFT_eSPI library does not have specific driver support for this board so I was wondering if anyone has had any luck in this scenario?
Arduino IDE 2.3.2
Board: ESP32S3 Dev Module (ESP32 by Expressif Systems)
TFT_eSPI Lib version: 2.5.43
The serial monitor output during boot is shown below:

Hello @mcornhill ,
Thank you for your information.
The 5'' HMI requires LovyanGFX as the drive library. The library TFT_eSPI doesn't support this display.
Squareline Studio provides support for TFT_eSPI so is there any plan to support this board using this library? Squareline Studio makes GUI development easy so having seamless support would make your boards much easier to work with for more makers who are not expert programmers.
Hello @mcornhill ,
Yes, Squareline studio supports the TFT_eSPI library
When using the Arduino framework (our sample program uses Arduino), only Arduino with TFT_eSPI can be selected，but this does not mean that only TFT_eSPI is supported.
The 5-inch HMI screen is an RGB screen, and the TFT_eSPI library does not support this 5-inch screens. It is more appropriate to use LovyanGFX.
