DWIN UART TFT Displays: Simplified Communication for You

DWIN's UART (Universal Asynchronous Receiver-Transmitter) TFT displays are a type of colour TFT LCD that communicate with a microcontroller or microprocessor through a UART interface. UART is one of the most common communication protocols, and it is widely supported by almost all microprocessors and microcontrollers The UART protocol allows these displays to be easily integrated into systems without requiring complex parallel interfaces, which are common with traditional TFT displays.

KS: uses up most of your GPIO pins. Libraries are available e.g. U8g2

ST: SPI uses few pins. ST misbehaves on SPI bus. Libraries are available e.g. U8g2

I2C: uses few pins. I2C is slow but practical for 128x64. They do not say what controller. We do not know commands. We do not know if it misbehaves on I2C bus. I do not know any library.

UART: uses few pins. Would be convenient for Mega with spare hardware Serial pins. We do not know commands. I do not know any library.

It would be relatively easy to guess the I2C and UART commands if I had one on my desk. I have too many displays. I don't want to buy another one (or two)

ORIC Electronics supply professional and honest service.

Perhaps Olikraus has seen the I2C or UART displays.

If not, my advice is to buy a ST. Use software SPI if you have other SPI devices on the hardware bus.

I do not like Blue displays. The Yellow ones work in daylight. The Gray I2C one looks nice but not much good without a library.

Have you looked at OLED or TFT displays?
