Troubleshooting

This link will contain common problems seen in labs as an aid for debugging.

Required Parts (all students)

During this lab, you will build up a single board microprocessor system based on the dsPIC33EP128GP502. The first hardware experiment is #6; in addition to the parts kit supplied as a part of this course, you will need to purchase or reuse the protoboard that you used in Digital Devices (ECE 3714). This protoboard will be needed on a continuing basis starting with Experiment #6, with the circuit remaining on the protoboard between experiments. If you are taking another lab course that requires a protoboard, then you will need to purchase a second protoboard.

You may purchase a used part kit from a previous semester from a student, but it is your responsibility to ensure that it is complete and the parts functioning. However, you may not use a pre-assembled protoboard. If you show up for the first hardware lab with more connections than needed for that lab, you will be asked by the TA to remove those connections. Part of the learning experience of this lab is to bring a microprocessor system to life from scratch, and using a pre-assembled protoboard from a previous semester defeats this purpose.

Computer

You must have a computer that meets the requirements of the Bagley College of Engineering.

Breadboard

The parts kit does not contain a breadboard; you will need an unpowered breadboard that has at least two rows on it, power/ground strips, and a baseplate with power posts.. The first one is what you want. The second one is too little.

Multimeter

Your meter should be able to measure voltage, current, and resistance. Capacitance measurement capability is helpful to check parts. Alligator clip or gripper type leads are also helpful.

Wire

#22 gauge solid wire, or you can use precut lengths like these:

Wire cutter / wire stripper

Recommended Parts (all students)

Small pair of needlenose pliers

Jumper wires

IC Chip Extractor

Distance Students Only

PIC programmer

Before the PIC can be used for labs, it needs to be programmed with the serial bootloader firmware. This is done during Lab 6 by a TA. However, online students will need to purchase a PICkit3 programmer as shown below.

Make sure it comes with a USB cable and a ribbon cable. The socket (lower left) is not necessary.

Parts Kits

On-campus students receive a parts kit during Lab 5, which contains the following items:

Spring 2024

Distance Students will need to purchase their parts individually. Below are explanations of each item from the above list. Links are not endorsements, nor are they necessarily the cheapest source of each part - they are used for illustrative purposes only. Some possible online sources for parts include Amazon, eBay, Mouser, Digikey, Jameco, and Electronix Express. Be sure to purchase through-hole parts that will fit on a breadboard (as opposed to surface mount).
