Posted on October 03, 2005 at 10:21Hello,
I'd like to build an ascii frame with several ASCII char received on an UART.
I want to process like this :
UART interrupts the main() every time a char is received.
Every ASCII char should be saved in a chart.
When the whole frame is received (detected with a end of frame marker (ETX) ), I decode the message in the main() function.
My question is :
where can I declare the Message[] chart (in main(), in the startup file,...) ?
How can I pass the start address of the chart to the UART interrupt subroutine ?
Thanks for your advises,
Manu
