For eg, if i only want to send data (digital or any integer) to laptop through USB, should i use usb_putc in my code? The data is from circuit, eg from a switch and when the switch is on, high (1) signal will send to PIC.

Please give me hints, thanks!!!

Another question: putc () sends character to the buffer, what the character here mean? Is digital signal or any integer number also can be considered as character? Thanks for reply......

A 'character', is an 8 bit binary value.
Can be the ASCII representation of a number, text, or a number itself. What you do _with_ characters, is 'up to you'.

Best Wishes
