#89918 - Scan keyboard "matrix" style Responding to: ???'s previous message |
Check the datasheet of the MM74C923 or 922 and learn more about keyboard scanning. You can use this component or write your own code do let the processor do the same. Some MCU's have build in features for keyboard scanning. The price of the 923 is almost just as mutch as the processor itself so its all about how "valueable" your time is. |
