JOY-iT SBC-LCD01 1.3 Inch HD-IPS-TFT-LCD Display

GENERAL INFORMATION

Dear customer,
thank you for choosing our product. In the following, we will show you how to use this device.
Should you encounter any unexpected problems during use, please do not hesitate to contact us.
Note that before you can use the display, you must solder the pin header!

USAGE WITH THE NODEMCU

Connection

Code example
The SBC-LCD01 has a logic level of 3.3V, making a NodeMCU recommended for this application. To use a NodeMCU with the Arduino IDE, you must first add the board. To do this click on File → Preferences. There you add the following link Additional board administrator URLs.

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Now you can download the library in the Arduino IDE. There you go to the library manager, which you can find under Sketch → Include library … → Manage libraries …. There you install Adafruit ST7735 and ST7789 Library and the Adafruit GFX Library using the search bar. Now you can download a sample code here, where an image is displayed on the screen.
Make sure that you select the NodeMCU as board also under Tools, as well as the correct port.

Please note, if you want to upload the code, you have to keep the flash button pressed!

Code example with SPI
We offer you two sample codes for the Raspberry Pi. One is a control via SPI and the other one via a frame buffer. In this part the operation via SPI is explained.
First enter the following command to enable SPI on your Raspberry Pi.
sudo raspi-config

There you activate SPI under 5 Interfacing Options → P4 SPI. Then run the following command to restart the Raspberry Pi to put the changes into effect.
sudo reboot

For this code example we use the library RPI ST7789, which was publis-hed under the MIT Lizenz. To do this, insert the following commands one after the other to successfully install the library.

sudo apt-get update
sudo apt-get install python3-rpi.gpio python3-spidev python3-pip python3-pil python3-numpy git clone https://github.com/rusconi/Rpi-ST7789.git
cd Rpi-ST7789
sudo python3 setup.py install

Now you have successfully downloaded the library. You can download the sample code here or use the following command to download it di-rectly to your Raspberry Pi.
wget https://joy-it.net/files/files/Produkte/SBC-LCD01/SBC-LCD01-Python.zip

You must download this file to have the image file on your Raspberry Pi. Now you can execute the following commands to project the image file on your LCD.

unzip SBC-LCD01-Python
cd SBC-LCD01-Python
sudo python3 image.py Joy-IT-240×240.png

In the following you will additionally find our code:

Use with a Framebuffer
We explain here how to set up the frame buffer fbcp-ili9341 to use it with this LCD screen. This library was published under the MIT-Lizenz.
You must first deactivate SPI, if you have activated it earlier. Therefore, go back to the configuration of the Raspberry Pi.
sudo raspi-config

There you deactivate SPI under 5 Interfacing Options → P4 SPI. Now you have to edit the config.txt and comment out a command. You open the config.txt with :
sudo nano /boot/config.txt

There you remove the hash at hdmi_force_hotplug=1. You can save with CTRL + O and leave the editor with CTRL + X. Now you must restart the Raspberry Pi with the following command.
sudo reboot

Now you can install fbcp-ili9341 by executing the following commands one after the other:
sudo apt-get install cmake cd ~
git clone clone https://github.com/juj/fbcp-ili9341.git
cd fbcp-ili3941
mkdir build

You must edit the display.h before continuing with the setup. Therefore, open the display.h with the following command:
sudo nano display.h

There you exchange line 83 #define DISPLAY_SPI_DRIVE_SETTINGS (0) with #define DISPLAY_SPI_DRIVE_SETTINGS (1 | BCM2835_SPI0_CS_CPOL | BCM2835_SPI0_CS_CPHA)

ifndef DISPLAY_SPI_DRIVE_SETTINGS

define DISPLAY_SPI_DRIVE_SETTINGS (1 | BCM2835_SPI0_CS_CPOL |

BCM2835_SPI0_CS_CPHA) #endif

You save again with CTRL + O and leave the editor with CTRL + X. You can now continue with the setup by executing the following commands one after the other.

cd build
cmake -DST7789VW=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_RESET_PIN=27 -DGPIO_TFT_BACKLIGHT=18 -DSPI_BUS_CLOCK_DIVISOR=8 -DBACKLIGHT_CONTROL=ON ..
make -j
sudo ./fbcp-ili9341

Now you will see your desktop on your 1.3″ display.
