How do you choose the right PIC testing tool?

1 PIC Testing Tool Types

Different types of PIC testing tools exist, depending on what you want to test and how. For example, in-circuit debuggers (ICDs) connect to the PIC and allow you to monitor and modify its operation while it is running. This is useful for debugging complex code and logic errors. In-circuit emulators (ICEs) replace the PIC and simulate its behavior, allowing you to test your code and hardware without affecting the actual PIC. Logic analyzers capture and display the signals on the PIC's pins, helping to analyze communication between the PIC and other devices. Oscilloscopes measure and display voltage and current of the PIC's signals, which can be used to check the quality and stability of power supply, clock, and analog inputs/outputs. All of these tools are useful for troubleshooting various issues.

2 PIC Testing Tool Features

When choosing a PIC testing tool, you should consider its compatibility, performance, usability, and cost. Make sure the tool is compatible with your PIC model, programming language, and development environment. Check the speed, accuracy, and resolution of the tool to see how they affect your testing results. Evaluate the ease of use, interface, and documentation of the tool to determine if they suit your preferences and needs. Compare the price, availability, and warranty of the tool to determine if they fit your budget and expectations.

3 PIC Testing Tool Examples

To give you an overview of the PIC testing tools available, some of the most widely used ICDs are the PICkit 4, the MPLAB ICD 4, and the MPLAB Snap. These are official Microchip tools that support a range of PIC models and features, as well as integrating with the MPLAB X IDE. Additionally, some of the most common ICEs are the MPLAB REAL ICE, the MPLAB PM3, and the PICkit 2. These also come from Microchip and offer high-performance simulation and programming capabilities. Third-party logic analyzers such as the Saleae Logic 8, the Logicport, and the Bus Pirate can capture and decode various protocols and signals from your PIC. Lastly, some of the most affordable oscilloscopes for PICs are the Rigol DS1054Z, the Siglent SDS1104X-E, and the Hantek DSO5102P. These tools can measure and display electrical parameters and waveforms from your PIC with features such as math, trigger, and storage modes.
