PIC Projects


Posted on Feb 4, 2014

The 12F629/675 PICs are small 8 pin DIP devices that are ideal for our applications. They include and internal oscillator, a comparator, an analog/digital converter and timers. The Microchip PICkit1 is an ideal USB programmer. PicBasic Pro (PBP) is an easy to use package for those who have no penchant for learning the arcane language of assembler.

PBP can be integrated with a free download from Mecanique called MicroCode Studio (MCS) that makes programming in PBP much easier. Microchip MPLAB is a free and superb compiler that can be downloaded from Microchip. The real treat is that MCS integrates with MPLAB and PICkit1 HI-TECH Software has release of a totally free ANSI C compiler to support selected Microchip devices. The HI-TECH PICC Lite compiler is a freeware version and supports the 16F877, 16F877A, 12F675, 12F629, 16F627, 16C84, 16F84 and 16F84A devices. This article was written to trace the steps taken by Ironsides in his quest to understand and program PICs for use in radio control applications. CatsEyes acted as mentor. The primary interest was sparked by the use of PICs to trigger digital cameras in aerial photography. However, it soon became obvious that PICs opened up a whole Pandora`s box of possibilities for radio control in a number of applications. Besides a single step operation such as trip a shutter, the programming of a PIC with multiple output lines offers up many possibilities, many of which derive from the extensive use of PICs in robotics. For example, an airborne PIC could be used to give a much more realistic undercarriage operation with multiple steps that are spaced in operation - using only one radio channel for to control a sequence. So what is a PIC By one definition, it is a Turkish cloth measure, varying from 18 to 20 inches....
