coll circuit

This easy programmer will settle for any device thats enhanceed by way of software program (eg, IC-Prog 1.05 by means of Bonny Gijzen at www.ic-prog.com). The circuit is primarily based partly on the ISP header described within the SILICON CHIP \"PIC Testbed\" mission but additionally features an exterior programming voltage provide for laptops and for different state of affairss the place the voltage present on the RS232 port is insufficient. This is completed the use of 3-terminal regulators REG1 & REG2. The PIC to be programmed can be hooked up on a protoboard. This makes advanced socket wiring to support more than one tools needless. 16F84A, 12C509, 16C765 and different softwares have all been used successfully with this instrument.
