I am using the LCD with ESP32 developmental board.
I am unable to communicate with the LCD and send data to it. I don't know where I am going wrong.
Here is the link to the docs. Not being computers engineer, I am very bad at reading these things. Can someone please help find the correct doc and find in it the reason my below code is not transmitting data to the LCD?
The connections are simple.
Rx pin of the LCD is soldered to Tx pin of ESP32 board.
The Tx pin of the LCD is soldered to the Rx pin of the ESP32 board.
The LCD is powered externally via a 5V adaptor.
LCD and ESP32 have common ground.
No demo code or manual given by the vendor. The documents detailing the communication protocol (In the link shared in my original post) are too technical for me.
I found the code I first used here, but its for the resistive LCD version. It works fine in the video, but on my capacitive LCD no response.
I don't found anything about the protocol in document in the link. It contains a module datasheet only.
Please let me know in which file and what page range you saw the protocol description?
