Raspberry-ssd1306

ssd1306 Command Line Tool for RaspberryPi.
It also works with OrangePi / NanoPi.

You can operate from command line.
You can choose Hardware-SPI/Software-SPI/I2C Interface.

Software requirement

• WiringPi Library
  This project uses the wiringPiSetup() function to initialize GPIOs.
  If you use it on a board other than the RPI board, you may need to change the WiringPi number.
  As far as I know, there are these libraries.
  • WiringPi for OrangePi
  • WiringPi for BananaPi
  • WiringPi for NanoPi
  • WiringPi for Pine-64

Change font style

You can choose the font style.
Please change here.

  // You can change font file
  Fontx_init(fx,"./fontx/ILGH16XB.FNT","./fontx/ILGZ16XB.FNT"); // 16Dot Gothic
//  Fontx_init(fx,"./fontx/ILMH16XB.FNT","./fontx/ILMZ16XB.FNT"); // 16Dot Mincyo

---

Font File

You can add your original fonts.
The format of the font file is the FONTX format.
Your font file is put in fontx directory.

Please refer this page about FONTX format.

---

Font File Editor(FONTX Editor)

There is a font file editor.
This can be done on Windows 10.
Developer page is here.

This tool uses the following as default fonts:

• fontx/ILGH16XB.FNT // 8x16Dot Gothic
• fontx/ILMH16XB.FNT // 8x16Dot Mincyo

Changing this file will change the font.
