my configuration bits is set as the picture.. but still cant make the pic it display thing on the hyperterminal...still got any suggestion?

The first thing we need to do is make sure the PIC is running at the speed you think it is, or know what speed it is running at.

These USB chips can be confusing ( for me anyways ) when it comes to setting the PLL and all. Bruce has a good explanation here that I refer to.

So if you set the configs as he has them the PIC should be running at 48MHz.
DEFINE OSC 48

To check the speed write a code that will blink an LED at one second on and one second off.

Then refer to the PBP manual under SEROUT2. There it shows how to connect the chip to a PC. Send some text to a terminal.

When this is all working we can "talk" to the VDIP.

for me also confuse for that part...so i change the pic 18f4550 to pic16f873A..this will more easy (i think)...now i try make it working on hyperterminal ....

i still cannot display on the hyperterminal...still got any solution?

Darn...

Check the pick with a one second blink to see if it is running at the expected speed?

Using a 232 type chip between PIC and PC?

Post the exact code and configs you are testing with.

Maybe we will see some thing.

i testing with the code i post b4..i got connect to 232 using max232..i already test the mode with 84,8276

I would like to see you test a simple "hello world" to the PC without the VDIP involved.
At this point we do not know where the problem is. Need to narrow it down.
