Videos: MPLAB ICD 3 In-Circuit Debugger

MPLAB® ICD 3 In-Circuit Debugger System is Microchip's most cost effective high-speed hardware debugger/programmer for Microchip Flash Digital Signal Controller (DSC) and microcontroller (MCU) devices. It debugs and programs PIC® Flash microcontrollers and dsPIC® DSCs with the powerful, yet easy-to-use graphical user interface of MPLAB Integrated Development Environment (IDE).

The MPLAB ICD 3 In-Circuit Debugger probe is connected to the design engineer's PC using a high-speed USB 2.0 interface and is connected to the target with a connector compatible with the MPLAB ICD 2 or MPLAB REAL ICE systems (RJ-11). MPLAB ICD 3 supports all MPLAB ICD 2 headers.

This tip, from one of Microchip's Field Applications Engineers, shows MPLAB IDE users how to set up pre- and post-build batch files for execution as part of the project build process.

Video: Introduction to mTouch Capacitive Touch Sensing

Touch sensing is fast becoming an alternative to traditional pushbutton switch user interfaces, because it requires no mechanical movement, and it enables a completely sealed and modern-looking design. Expanding beyond the consumer market, touch sensing is beginning to take hold in medical, industrial and automotive applications for reasons such as aesthetics, maintenance, cost and cleanliness.
Microchip’s mTouch™ Sensing Solution provides a free and easy method for designers to add touch sensing to applications utilizing PIC® microcontrollers without the cost of fee-based licensing and royalty agreements. Being a source-code solution further helps engineers quickly integrate touch sensing functionality with their existing application code in a single, standard microcontroller, thus reducing the total system cost associated with current solutions.

An example PIC32 assert() function implementation

I wrote a simple assert() implementation that you can customize for your application. This implementation writes the assert message to a simple array for inspection in the watch window. You should be able to easily customize the assertion failure behavior for your application.
