- Sun Nov 27, 2016 5:34 am #58739 Hi all,
I am looking for a 3.2"/3.5"/3.8" TFT LCD preferably 480x320 pixel and 262k colors that
can be used attached to an ESP8266.
On china sellers sites (banggood, aliexpress,...) there is a moltitude of displays having
this characteristic but I am not sure what I should check other than SPI.

Can someone tell me what I should check and/or where to buy it?

TIA,
Gianni

Search by Nextion.

Ok, thank for your answer.
Nextion display are more expensive respect other LCD having ILI9341 or ILI9488 controller.
Can you explain me if SPI or HSPI is the only feater I should check to understand if a LCD is esp8266 compatible?

TIA,
Gianni

I2C: use just 2 wires but, until now, all is done by software, with lots of "drawings" may be CPU expensive without time to other tasks (wifi, read sensors...)

Serial: best I found was Nextion.

LCD having ILI9341 or ILI9488 controller uses 4 wires, but gives more time to the CPU, because is done by hardware.
