This simple circuit can be used to program the PIC16F84 and similar “flash memory” type parts. It uses a cheap 555 timer IC to generate the programming voltage from a +5V rail, allowing the circuit to ...

If you have an idea for a fairly simple USB device but don’t want to invest in the more expensive microcontrollers, this library will be of interest to you. It’s a software implementation of the ...

Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings. In ...
