To get started using the Sino:bit, see this Adafruit guide. There is one omission of a required library HT1632 that should be added in the library manager. While the Sino:bit features a 12 X 12 matrix of LEDs the character representation is limited to an 11 X 11 grid, due to the dimension of the font I used, SolidZORO's zpix font. So, many characters in Chinese, even simplified as found here, will be too complex to represent effectively, but it is a start!
The app is made in Processing using export as application feature. For Mac this means it is self-signed and I find must be moved to Desktop, Documents, or Application folder for the text file output to work. If left in Downloads the app freezes when trying to run output. I must give a shout out to this resource (last post in the thread) for pasting clipboard content into a Processing app. I struggled with this and finally got it to work thanks to this! Without a paste from clipboard feature I couldn't see being able to make this into an app. As far as I can tell Chinese characters can't be typed in to a text field in a Processing sketch, as much as I tried (though I am not very good at it).
To use the char array in an Arduino sketch, pass it to a drawBitmap function call like this:
#include <sinobit.h>
Sinobit matrix = Sinobit();
const unsigned char myBitmap [] PROGMEM = {
// char bitmap of 见
0x7f,0xc0,
0x40,0x40,
0x40,0x40,
0x44,0x40,
0x44,0x40,
0x44,0x40,
0x44,0x40,
0x04,0x00,
0x0a,0x20,
0x32,0x20,
0xc3,0xe0,
0x00,0x00,
};
void setup() {
matrix.begin();
}
void loop() {
matrix.drawBitmap(0, 0, myBitmap, 12, 12, 1);
matrix.writeScreen();
}
Here is the app for Mac.
Here is the app for PC (not tested yet).
