Re: [ECOS] io_read

["Sicheri Marco" <m.sicheri@ctsgroup.it>]

Hi,
I resolve my problem, I read the source. Thanks!
This is my code:
if (cyg_io_select(ctsUartHandle[uartID], CYG_FREAD, uartInfo) == false)
    return (CPSRC_UART_NOTREADY);
else
{
    uartBufLen = 1;
    err = cyg_io_read(ctsUartHandle[uartID], &uartChar, &uartBufLen);
    ...
}
Thank all for yours answer.

But:
I can use the read() or the cyg_io_read()...
Which do you recommend to use? read() or cyg_io_read()? Or are they alike
right?
Thanks and good work!

Ossequi,  (Best Regards/Obrigado)
