lpuart_demo

[kalajiao]

I call the code of the official lpuart routine and make a small change here, but why does the serial port receive only 'Hello W' after I do this? If I send 'Hello Board' without making any changes and follow the code in the official routine, I do receive 'Hello World', so I don't understand why

Hi@kalajiao

       The process of receiving and sending data is correct,  the error caused by 'bufferIdx'.You need to modify 'bufferIdx' value.

How do I change 'bufferIdx'? The 'bufferIdx' routine does not define a type of uint8_t directly, and then the program automatically adds it to meet the condition. Can you tell me how to change this? I don't quite understand. I'm sorry to trouble you.
