This is an Arduino project aimed at driving a pair of Sure Electronics DE-DP14211 P7.62 32X16 RG Bicolor LED Dot Matrix boards. These boards use an Holtec HT1632C controller.
Based on the HT1632C library. Tested with an Arduino Uno R3.
Begin by installing Ino. On a Mac with brew installed, you can simply run brew install ino.
Next, build this project and upload it to your Arduino:
ino build
ino upload
You can monitor the serial port using ino serial (use Ctrl+A Ctrl+X to exit) or something like:
stty -f /dev/tty.usbmodem1411 9600 -parity cs8 -cstopb
tail -f /dev/tty.usbmodem1411
(Change your serial interface accordingly. ino serial will guess it for you.)
After running the previous stty command, you can send commands to the board manually using one of the following:
cat commands.txt > /dev/tty.usbmodem1411
echo "test" > /dev/tty.usbmodem1411
Connect Input of Matrix 1 to the Arduino following the following schematics. Connect Output of Matrix 1 to Input of Matrix 2, including +5V and GND.
