Start off with a blank Tiny030 pc board:
The first stage is to assemble and test the CPLD by driving a few LEDs. The CPLD is Altera EPM7128SLC84 hosted in a through-hole 84-pin PLCC socket.
Add the 68681 40-pin socket because jumpers are needed to connect CPLD output to 7-segment display. Populate the EPM7128SLC84 as shown and insert 4 jumpers from the 68681 socket as follow:
- pin 12 to pin 35
- pin 13 to pin 37
- pin 14 to pin 9
- pin 15 to pin 21
This connect 4 currently unused CPLD outputs to 4 of the 7-segment display. Also populate the oscillator. Here is the Altera CPLD programming file.
