Need a driver C code for serial communication between microcontroller and PC

[sandy_m2k2]

hi.

i have to make a microprocessor controlled intelligent battery charger with usb interface.the programming should be in c.can i download an appropriate driver program for the usb interface? i need a driver that will enable serial communication to take place between the microcontroller (philips lpc2148 with arm7) and the pc.

Can anyone point me to the right code or give me the code required?

Keil.com has the sample code for a flash device,a audio device and an human interface device.which would be appropriate for this ?


can anyone help me pls.

HID (Human Interface Device) would be appropriate for your project
