Just thought I would write a quick guide if like me your struggling to get your 1.3″ screen with ST7789 driver to work on a Rapsberry pi. Follow along below to get it up and running in no time. I need to point out that you will NOT be able to get this screen working on the breakout board is comes on. You can ether make your own breakout board or use the one I made HERE and can be ordered from oshpark HERE
The pinout for the screen I’m using is the same as waveshare use on there raspberry pi HAT board found HERE
- SCLK – PIN 23 BCM 11
- MOSI – PIN 19 BCM 10
- DC – PIN 22 BCM 25
- CS – PIN 24 BCM 8
- RST PIN 13 BCM 27
- LEDK – PIN 6 GND resistor 10 ohm
- LEDA – PIN 1 VCC
Here is the pin numbers for the ribbon on the bare screen
Once that’s all wired up we move on to the software. I have copied all that is below from a PDF waveshare gave me. I copied it because it’s really hard to highlight and copy the text off of the PDF
Before we get started we need to go into raspi-config and turn on SPI. To do this run
Then go down to option 5 “Interfacing Options”.
Then select P4 “SPI” and enable it.
After that just exit by selecting finished at the bottom.
Next we need to edit the file below
Added the text below to the file then save and exit
spi-bcm2835 flexfb fbtft_device
Next up we need to make a new file as shown below
Add the text below to the file then save and exit
options fbtft_device name=flexfb speed=32000000 gpios=reset:27,dc:25 options flexfb setaddrwin=0 width=240 height=240 init=-1,0x11,-2,120,-1,0x36,0x00,-1,0x3A,0x05,-1,0xB2,0x0C,0x0C,0x00,0x33,0x33,-1,0xB7,0x35,-1,0xBB,0x1A,-1,0xC0,0x2C,-1,0xC2,0x01,-1,0xC3,0x0B,-1,0xC4,0x20,-1,0xC6,0x0F,-1,0xD0,0xA4,0xA1,-1,0x21,-1,0xE0,0x00,0x19,0x1E,0x0A,0x09,0x15,0x3D,0x44,0x51,0x12,0x03,0x00,0x3F,0x3F,-1,0xE1,0x00,0x18,0x1E,0x0A,0x09,0x25,0x3F,0x43,0x52,0x33,0x03,0x00,0x3F,0x3F,-1,0x29,-3
We need to install some software. Use the commands below to do so.
sudo apt-get install cmake git git clone https://github.com/tasanakorn/rpi-fbcp cd rpi-fbcp/ mkdir build cd build cmake .. make sudo install fbcp /usr/local/bin/fbcp
To make it run at boot time we need to open the file below
Then here is the important part you need to add the following text to the file be it has to be above the word “exit” at the end of the file. Save and exit
You can reboot now to see if the screen is working. If you want to change the screen res you will need to exit the file below
Just add this to the end. Uncomment/comment out the rotate lines as you see fit
hdmi_force_hotplug=1 hdmi_cvt=240 240 60 1 0 0 0 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 #display_rotate = 1 # Upside down display_rotate=2 #Right way up #display_rotate=3 # Left
