  • Microchip PIC

    Microchip is the manufacturer of the famous PICmicro� microcontrollers. It’s a RISC chip with some 35 instructions. I had worked on this about two years back. And I remember becoming very excited about programming the PIC. So much so that, for quite a few nights, I used to get dreams about the PIC’s instruction set :-)

    One particular favorite of mine was the btfss instruction, which stood for “bit test F, skip if set” – which would basically skip the following instruction (which would almost always be a goto) if a particular bit in the F register was set. Hoo boy. For a complete list of instructions, check here. Some of them are funny.

    PICs have been used in a variety of electronic gizmos. The project I was involved in required the development of a solar charger-cum-controller for street lights. Microchip also provides their own IDE for developing and debugging PIC applications – it’s called MPLAB, and is available for free download from their site.

    I had several ideas for useful products that can be developed using the PIC. At the time, however, I still had my engineering exams. And had to do a project as part of the course. I wish I had done something based on the PIC. I regret it to this day. What did I do for my project, you say? I and a couple of my classmates went to Wipro for the project. Frankly, I do not know what we did there. We did not learn anything there, nor did we do anything practical.
