This is an example that demonstration how to control stepping motor via USB interface.The PC software program with delphi.The project use CPU PIC18F4550 with full speed USB interface at 48MHz, USB 2.0 compliance.The firmware for this example program with MPLAB C18 with USB driver from Microchip.

This is a small ajustable clock, It’s made based on PIC16F84A microchip.The hardware part is very simple because it only uses 74hct238 demultiplexer, 4×7 segments, and some rezistors. The software part is programmed through a device connected to serial port with icprog and made/debuged with MPlab.[more]

Kees Krijnen writes:The Microchip PIC16C84 was one of the first serial in-system programmable microcontroller. I saw PIC serial programmers published in Electronic magazines in 1993. Today, many PIC programmer circuits - for serial and parallel PC ports - are published on the Internet.Despite its somewhat unusual design - like the 128 byte page RAM/Register direct/indirect memory mapping - it is a popular microcontroller, easily available and programmable now as flash microcontroller 16F84. The developer environment MPLAB from Microchip is free of charge and many application examples are available.[more]

This frequency synthesizer use MAX038 waveform generator devices from MAXIM and control by PIC16F877 which is a popular microcontroller from Microchip.But,the author not made a schematic detail, he made a PCB for this project only which the main PCB include with MAX038 high frequency waveform generator, powersupply and 16F877 PIC controlling the frequency synthesizer.But,over all design look very nice.[more]

It’s very easy! This is a simple GAL programmer that hobbyists will able to use the GAL very easy. Building costs are less than 1/10 of cheaper GAL programmers. This is good for parsonal use. And added an optional function to program to the Microchip’s PIC with using a socket converter.[more]
