datalogging from pic16f877a to usb-stick

[skimask]

I did make some pic projects by myself, but this is the first time I use serial communications. Hserin and hserout works perfectly with pic to pc. But i can't get serin and serin2 etc to work properly. Could it be that I use a bootloader so there must be an extra code inserted in pic basic pro just like lcd and bootloader

Well then, let's see some code. That's what we're here for...

I tried it without an bootloader and programmed th pic16F877A with an usb programmer this works ok! Does anybody know how to get the stuff working with a bootloader I use the bloader from sparkfun

this is the code that works only if you not program it with a bootloader

I really appreciate it that everybody is so helpfull cause the simple things are sometimes though to crack! When I'll receive my dosonchip and gps receiver I'm going to test it a lot. Now I'm just doing research to everything I need to use in my project.
