    PMOD KYPD

    Posted by John Brown on 9th Aug 2022

    I combined the PMOD KYPD with a PCF8574N discreet DIP IC to an ATtiny817. It was a fun project that enabled me to read the keypad with 3 pins of the 817. I used the Digilent Analog Discovery to analyze and debug.

    Solid Feel

    Good quality keypad for hex or octal entries. Much better than using a membrane keypad as was found on so many single board computer kits in the seventies.

    Almost perfect

    This is a great keypad. It would be perfect if they had included diodes in the key matrix to allow for multiple key presses to be accurately detected.

    Great for the hobbyist

    This is a nifty little keypad that when combined with the Pmod OLED or similar simple display can be the basis for a project to build a simple four-functiom calculator. I found this a fun and relatively cheap way to continue learning about FPGA and VHDL with something more interesting than buttons/flashing LEDs, but less challenging/rigorous than something like DSP.
