i am not receiving proper data, i am using GHS IDE to debug my driver but am unable to receive the data in the dock light
Hi,When you are telling, you are not receiving proper data. What is the observation at your end. What is your observation on the UART lines. What are the observations when you try to debug?Best Regards,Vasanth
These data i am receiving , i am transmitting a string HELLO
[TX] - ABCD
[RX] - HHHHHH
