19 YKM 7-seg driver

19 : YKM 7-seg driver

Design render

How it works

The string is shown by individual characters to the 7-segment LCD. By default with all pins except Clock being Low, the chip will cycle through all the characters depending on clock speed. To display individual characters manually, set HIGH to counter pin and BCD. Then select the bits 0-3 manually.

How to test
