Hi,
I work on a software to programming the flash memory of a xc2267m uC via RS232.
I read the user's manual :
"The XC2200M scans the RxD line to receive a zero byte after entering UART BSL mode and the respective initialization. The zero byte is considered as containing one start bit, eight 0 data bits and one stop bit. [...]. Using this baudrate, an identification byte (D5H) is returned to the host that provides the loaded data."
But I tried to sent "0" with the software "ComTools", and I have the answer "F8". Why?
The following lines are what I see on the ComTools window (in hexa, baudrate : 19200, green = the uC, blue = me) :
1B 49 04 69
FE
0
F8
The first line is send because of a program in the uC.
I tried to send another char, the uC answer "FF" instead of "F8".
Can anyone help me?
Problem solved
