BCD Keypad with 7 Segment LED Display

[mrdon219]

Hi SNAP Tech Enthusiasts,

Here's a SNAPpy script that can convert 4Bit Binary data into its equivalent Decimal value and display it on a 7 Segment LED Display. In addition to this Digital Data Converter Tutorial, this SNAPpy script can be applied in various Wireless Embedded Controls Applications with minor changes to the script. The Lab Project can be obtained from the Application Notes Forum. Check it!!!

Possible source of confusion... the ASCII-ART wiring diagram in the script source code does not match the implemented code or the documentation.

It appears SW2 got moved from GPIO_7 to GPIO_4.


SW2_PIN = 4

# Wiring Diagram
