About Library

This library is forked from LED-Matrix-Display-Driver-Library STM32. The source code to work with . With simple modification, this library can be compatable with more MCUs.

• MCU: NuMaker 131 Uno

  • The driver and gpio is controlled by "NUC131Series_BSP_CMSIS_v3.00.004" and set directly to register.

• Display size: 64x32

• Color: RGB332

• Hue: 4 each R,G,B

  • If you want to change it to different RGB format or display size. You need to recalculate for buffer size and modify display fuctions.

• If you want SD Card support, you can look at ChaN's FatFS.

The pin setting funnction in DisplayInit() function is defined by "NUC131Series_BSP_CMSIS_v3.00.004", which can be found in the NuVoton's website

Before running the code

You need to install the corresponding board from "tools->boards manager"
In NuMaker 131 Uno, Install "NuMaker UNO"

How to run example

1. create a directory with the same name as example/_____.ino
2. copy ____.ino in to the directory you just created
3. copy all documents in "src" inside the directory
4. open .ino and run code

How to display image?

1. Convert your image file to .bmp
2. Use bmp2h.py to convert to byte array(.h) file
3. Inclue .h file to .iso
4. use displayLoadImage() function
