Hi,
Now I'm going to use 52833 USB_CDC_ACM , but there is no suitable type in SDK17.1.0. It's just have pca10056 .So I port to 52833 based on the 52840_pca10056 routines.
And I download the hex into the 52833. At present, the computer can recognize this USB serial port.
When I open the serial port assistant, there is no response when I want to send or receive data. I don't know where is the problem.
The serial port appears to be recognized, but is not programmatically manipulated.
When I debug, I go to the following place
If I comment two lines , and I wrote the UsbCdcWrite function.
That my serial port assistant will receive some data,but they are all 0
So I would like to know if there is anything I should pay attention to in porting routines? how to solve such problems?how to get me to port the program correctly?
Regards,
Wei
