compatibility with esp32 and weaveshare lcd
Hi! Is this library compatible with: LoLin32 (pinout below) chip ESP32-D0WDQ6 (revision v1.0) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz
And this LCD: https://www.waveshare.com/wiki/4inch_TFT_Touch_Shield
I can't display anything using ESP32 :-( With Arduino UNO works fine.
The display module designed for 5V MCU may not work for ESP32.
But from Weaveshare (link in my first post):
"STM32 The demo has been tested on XNUCLEO-F103RB, just insert XNUCLEO-F103RB as shown below. The model of XNUCLEO-F103RB is STM32F103RBT6. If you need to port the program, please connect it according to the actual pin and the schematic diagram."
STM32F103RBT6 accepts voltage: 2 - 3.6V
seems it is not an issue
OK, so, what I can do? Wires checked many times, LoLin32 pins checked. On Arduino UNO above LCD works. Now Im reading Waveshare product page and there is information: I/O VOLTAGE: 3.3V/5V DIP switches changed on LCD..
I have no idea..
Sorry, I did not have this display in hand and cannot support.
