# Raspberry pi 3.2inch TFT display

Many times, I've tried to configure my display on a `Raspberry 3b` with retropie. Fortunatly, I've found the correct answer of how to do that.

In This repo you'll see what I've used to make it works.

The driver for my screen is: `ILI9341`

[![screen example](./assets/tft-screen.jpg)](https://www.amazon.com.br/waveshare-Raspberry-Resistive-Raspbian-Provided/dp/B01HPV68UM)

`Note: Mine is not the waveshare version, but the version below.`

## 1. Install driver

First of all you need to install the drivers.

You can use the driver directly, which you can find [here](https://github.com/juj/fbcp-ili9341). But, a simpler way is to use [this script](https://github.com/goodtft/LCD-show/tree/master).

Just choose one, and follow the tutorial.

## 2. Fixing screen fps

After that, I've changed some configs at `/boot/config.txt`, to make smoother experience.

I changed the following lines:

```

dtoverlay=tft9341:rotate=270

and 

hdmi_cvt 480 360 60 6 0 0 0

```

to 

```

dtoverlay=tft9341:rotate=270,fps=40,speed=42000000

and 

hdmi_cvt 480 360 60 1 0 0 0

```

You can see the whole file [here](./config.txt)

# Throubleshooting

Newer Raspberry Osses don't work with this script, ensure you're using the Debian Bullseye based version.
