How to receive data in UART?

Hi Manjunathan,

Looking at your code briefly - the initial 'sciInit()' looks ok assuming you configured the sci correctly in HalCoGen.

But to me it looks like only 1 character is received over the UART. If this character is 5 then you do something with the het.
If not then you wait forever at the final while(1) loop. [meaning that if any more characters are received you ignore them].

Normally I'd expect there to be a loop around sciReceive and the if(d=5) so that if the first character isn't a '5' you allow the code to try again
until a '5' is received.

Also - side note - I would probably move hetInit(); to the beginning of the code with sciInit().
Otherwise it will take quite some time to actually start the PWM in response to the '5' because first you have to do the whole het initialization.

Best Regards,
Anthony
