i want to communicate from microcontroller to PC vice versa through USB port.
please guide me , that it is necessary to connect USB interface IC between PC and Microcontroller. as this IC is expensive, so is there alternative way to direct connect the usb port between microcontroller and PC.
Re: how to communicate btw PC and controller through usb por
you can use ft232 chip to make communication bet pc and mc.
or ,
you can use pic controller which has in build usb function , with this you can directly connect the mc to pc without any chip in between .
but , all above you need a driver in pc side for communication , for pic microchip provide it on there site , where as for ftb232 you have to find it .
