I'm trying to write an usb cdc driver program. its cummunicate between pc and arduino due.actually my aim is reciveing the data form arduino and I read in visual c++ (command prompt).how to suppose i read the data in vc++. I don't the flow(sequence of the process) of cdc driver porgram . please explain me ?...........
Finally got the MCB2300 Demo working. I had to use the driver stuff that comes with the DEMO so that it would start working. I loaded the program into flash. It took me a few days to get it working. But really not sure why I could not get it working right away. The first time I loaded the driver it gave an error. But the error went away the next time I powered the PC up.
Today I took a good look in Device manager and saw that not the COM Ports of my USB to RS232 adapter AND the USB VCOM port were set to 9600. I brought up Tera Term twice one instance for each port. Then I would type characters into one Tera Term window and see the characters go to the other Tera Term window. There was no echo occurring in the Tera Term window I was typing in. Also the program worked in both directions.
