Hello sir/madam i am very new to USB communication using lpc2148 and PC. I tried lots to neatly configure the registors but not getting. so help me to improve my code to communicate with PC. and how to send data to each other. Thnking you.
If you want to learn how USB, PCs and the LPC2148 work you might want to look for some documentation and manuals about said topics. Go find some examples for the chip, or close family members.
If you want someone to write clean tested code for you, then you're probably looking for a consultant to do your work, rather than just help you.
