Hi,

thks for the reply. Pls bear with me for I am a novice programmer. I connected the 16F628 chip directly to the serial port in the config as shown below:


Serial Port Pins : 16F628 Pins

TXD (Pin 3) -----[4.7K]------ MCLR ( Pin 4)

GND (Pin 5) ----------------- Vss (Pin 5)

DTR (Pin 4 ) -----[4.7K]------ RB 7 (Pin 13)

CTS (Pin 8) ----------------- RB 7 (Pin 13)

RTS (Pin 7) -----[4.7K]------ RB 6 (Pin 12)


To power up the chip, I connected the power supply to these pins on the 16F628.

Vdd (Pin 14 ) ------ + 5V
Vss ( Pin 5 ) ------ + 0V

Afterwards, I used IC-Prog and did a wirte of a hex file but was unsuccessful. No other programmer was used, just a direct serial port to chip connection. By all indications it should work right?
