How to use ATMEL ISP.
To use this ATMEL ISP board you need to download software ISP-3v0 developed by Muhammad Asim Khan and distributed by Prof. Wichit ‘s website or download at the buttom on this page.
After download software.
1. Connect ATMEL ISP cable to PC parallel port and power supply. (see Fig.5)
2. Run software ISP3.0 for Windows95/98/ME use ISP-3v0.exe and WindowsXP/2000/NT use ISP-XP.bat .
3. Select your devices from drop down list menu.
4. Click “Open file” to open hex file.
5. Click “Write” to program device.
How to use RS232 port.
To use RS232 port ,first build a simple RS232 cable.

AT90S1200 D.D.S. Function Generator
The presented project is a function generator for sinusoidal and square signals production. The output frequency covers the range from 10 Hz to 100 KHz with a step of 2 Hz.
The waveform synthesis is based on the D.D.S. technique (Direct Digital Synthesis) and the output frequency is selected through a microcomputer with an embedded thumb wheel keyboard.
Function Generator Technical specifications
Output Frequency: 10 Hz – 100 KHz (step 2 Hz)
Output Voltage:
Sinus: 0 – 20 Vp-p
Square: 0 – 20 Vp-p
TTL: 5 V
Output Resistance: 1 KOhms
