Edit: It appears TFT_eSPI won't work on that board, since "the interface has no DC pin so it is not compatible with the interface type supported by the library." (source)

Hello,

I'm a newbie, and can't get the display to work in Arduino.

What settings should I use in Bodmer's User_Setup.h file, considering the Read_User_Setup.ino returns the following:

TFT_eSPI ver = 2.4.72
Processor = ESP32
Frequency = 240MHz
Transactions = Yes
Interface = SPI
Display driver = 9341
Display width = 240
Display height = 320

MOSI = GPIO 23
MISO = GPIO 23
SCK = GPIO 18
TFT_CS = GPIO 15
TFT_DC = GPIO 0
TFT_RST = GPIO 2

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 27.00

Thank you.

Hello,

I'd like to move from a T-Display controller to a T8.

The original application used pin 21 and 22 for TX and RX respectively, but the pins are numbered differently on the T8.

Before I pull the soldering iron… can I just update and recompile the source code to use any IO pin I want instead?

Thank you.

Hello,

I know nothing about electronics.

I'm using the TTGO T-Display ESP32 4MB CH9102F Chip V1.1 to drive a Senseair S8 LP CO2 sensor.

From what I read, the TTGO pulls ~80mA while the Senseair uses 80mA average and 300mA at peak.

Since the TTGO has a plug, I was wondering if the combo could be powered by a single li-ion battery without any extra hardware, as an alternative to hanging a USB power bank.

Thank you.

Hello,

I just plugged this TTGO board onto a Windows 7 (32-bit) computer… but the driver is missing.

The page contains no driver for that controller with a CH9102F serial chip.

Where could I find the driver?

Thank you.
