I have tried changing the glcd.c file as per instruction but always get an error when i try to compile, even using the original glcd! I want to use this on a 18F4520, if anyone can compile the hex file for this uC i would really appreciate it very much. Thanks! bboth@live.com Hi

With no Rs232 port on my PC, I find I can replace the max233 level converter with a FT232RL USB to Serial chip which can be connected directly to the 18F2550 serial port. I used a FT232RL chip on a breakout board (BOB-00718) by sparkfun.com. As supplied, the RS232 logic levels are set at 3.3v and a little soldering is needed to set the level to 5v. I also had to modify the bootloader to run at 57600 baud in order for the loader to work with Windows 7; a slower rate is needed for Windows XP. Otherwise no problems. Many thanks, Drew Hi Steve.

Great Job and Many thanks HI Steve;

Any sugestion?? I make all the connections of the circuit image and I hoped that it would look like the picture on the top. hk: It works with a 20MHz crystal with 2 pins.
