Hi,

I have tried to send the data (unsigned char) to HyperTerminal by using printf as mentioned in previous posts.

printf("Data 1:%un",255); //Output result to UART
printf("Data 2:%un",32768); //Output result to UART
printf("Data 3:%un",32000); //Output result to UART

I found out that if I send the data value in between:

a. 256 to 32767, I will get correct result on the PC's terminal.

b. 255 and less than, I will get garbage on the terminal (e.g. if 255, get 65535, or if 254 get 512)

c. 32768 and more than, I get 0 on the terminal.

Anyone can have any idea, please advice? Thanks.

Note that I am using Keil uVsion3.
