4位7段显示驱动接口MC14489。- Arduino库。

This is a library for Arduino +1.0 so you can use a MC14489 to drive a 4-Digit seven segment display. It requires 3 pins on the arduino, a 5V source and ground. It only displays 4 numbers in the form of WXYZ. No decimal places (yet). Download the zip and extract to your libraries folder of Arduino. To output to the screen you use SSD4.screenWrite(WXYZ); Numbers will always display on the right if there are not enough to fill the screen. Ex. a value of 2, would write 0002 on the Seven segment display.
