Hardware Design
Now the fun part begins, we get to actually build the circuit. All the steps seen below follow the schematic.
Building The Circuit
Get your parts together and follow the schematic. I assembled the circuit in stages as you can see below...
·First the 74HC244 and 2.2kΩ/100Ω Resistors are connected.
·Then all the connections to the DB25 Connector are made.
·Finally, the connections to the JTAG connector are made.
·I probably make it look easier than it really is. It took me about 15-20 minutes to wire this breadboard circuit up.
