SCI Problem

martyseb63 — Tue, 11 Apr 2006 15:32:11 GMT

Hello,

I wanted to know how can we receive data with serial port on the MC9S08GT60.

In SMAC, there is a file nammed SCI.h.

For send a message, there is no problem, but to receive, I don't know how to do.

I tried SCIgets(...) but it doesn't work.

Can you tell me how can I do.

Thank for your help

Hi:

You should check for the RDRF flag in the Register SCI1S1. Something like this:

char Wait_for_RxCharacter()
{
while(!SCI1S1_RDRF);
return SCI1D;
}

Regards,

Alex

If you look at the SCI.c and vectortable.c the example code (i.e. accelerometerV2) uses an interrupt to capture data recieved on UART1... you have to be careful though the example code has recieved bits from UART1 and UART2 call the same ISR interrupt void Vscirx() and only clears UART1....

Hi,

I have same problem to use SCIgets()

It's an urgent need. please help me!
