Hi,

Not able to give a detailed error description?
Proteus schematic, which shows your actual and complete design?
How does the proteus scope picture look like?
How the real scope instead?

I don't use Hitech C but the code looks OK to me. It should send 'B' once per second at 38461.5 bits per second.

Note that simulators usually ignore things like the reset line and of course assume you are using the stated clock frequency and it is running correctly.

Brian.

Re: need help in configuring pic16f887 euart in hitech c

If it displays other characters then it means your PC baudrate setting is not correct. What terminal software are you using to capture the serial data ? Have you selected correct baudrate in serial terminal software that is same as then in code ? You might need to set baudrate in Control Panel > COM and LPT Ports > Your COM Port > properties > Baudrate to same as in code.

hi baileychic
am usingmikroc hyperterminal software for capture serial data and am using 9600 baudrate in the hyperterminal software.
i tried two different hyper terminal but the results are same in both of the hyperterminal..
i think there is a fault in the code???
 

Re: need help in configuring pic16f887 euart in hitech c

In Control Panel > Device Manager > Your COM Port

Did you check its baudrate settings ?
