(E)EProm, PIC and GAL Programmer
Below you find the programming device I use for my robot projects. The device is fairly generic: it has a 16 bits address port, an 8 bit dataport, an 8 bit control port and a simple programmable voltage source. Since I only use a few components: (E)EPROM, GAL16V8 and PIC16F84, the programming software is capable of handling just these components. The device is controlled by the LPT port in SPP mode. The software can be run under Windows 98/ME/NT/2000/XP. The latter three (WinNT, Win2000 and XP) make use of a driver to get access to the LPT port. In order to be flexible the programmer make use of adapters. For each type of device a suitable adapter is connected to the programming device.

On this page you find the schematics of the programmer and some adapters. As you can see the programmer consists of several TTL latches for storing address (IC1 and 2), data (IC 3 and 4) and control data (IC 5). Two bits (Q4, Q5)of the control-port are used to set the programming voltage. Q6 is used to control the direction of data and Q7 controls the lower/upper nibble selection of the LPT SPP-data input. That leaves 4 control-lines for programming signals to the 'programmee'.
- An adaptor for the Eprom 27C64, EEProm 28C64
- An adaptor for the GAL 16V8
- An adaptor for the PIC 16F84A
- An ICSP adaptor for the PIC 16F872
The program programmer.exe can program these devices. It loads a binary file (*.rom) to program the eproms, a jedec (*.jed) to program the GAL, and a binary file (*.hex) to program the PIC devices. The program is also capable to read and verify these devices.
windows版软件，看说明，要把那个*.sys文件复制到相应目录
