This simple programmer
will accept any device that’s supported by software (eg, IC-Prog 1.05 by
Bonny Gijzen at The circuit is based in part on the ISP header described in the SILICON CHIPPIC
Testbed” project but also features an external programming voltage
supply for laptops and for other situations where the voltage present on
the RS232 port is insufficient. This is done using 3-terminal
regulators REG1 & REG2. The PIC to be
programmed can be mounted on a protoboard. This makes complex socket
wiring to support multiple devices unnecessary. 16F84A, 12C509, 16C765
and other devices have all been used successfully with this device.
