This is all-new Version V4.0 3.2 Inch TFT LCD Touch Screen for Raspberry Pi display from waveshare is big (3.2″ diagonal) bright and colourful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display.
As a bonus, this 3.2 Inch TFT LCD Screen for Raspberry Pi V4.0 display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller.
This 3.2 Inch TFT LCD Screen display is an alternative solution for Raspberry Pi compatible HDMI display; the 3.2 inches Resistive TFT Touch Screen Display, which uses SPI Protocol (serial peripheral interface) to communicate with the main processor. It can be mounted directly to the GPIO pins and it doesn’t require any external power source.
In here we have a detailed explanation on how to install LCD drivers in a custom Raspbian image. The standard version of Raspbian does not include drivers for LCD touchscreens, so we will have to install and configure them manually.
Note: It is recommended to use a 5V 2A power adapter to power the raspberry dispatcher. Such as the use of PC’s USB interface to the raspberry power supply, may be due to lack of power supply raspberry can not cause normal start.
