AUART

[derricko]

I see from the driver file RS485.c. there is a session coded:

[Ttelmah]

RCV_OFF, is being created _by_ these lines.

It looks like a 'residuum', where, when originally written, in some earlier version of the compiler, different operations were needed for different hardware, so these lines were generated, with one probably giving a different setup_uart command, then later, the different line was changed to use exactly the same command, and instead of just having:

#define RCV_OFF() (setup_uart(FALSE);)

The old test was left.

Does no 'harm', except in making the code less readable, and the source a couple of lines longer. The final result will be the same, since only one of the two duplicate lines will ever actually be used.....

This is a common type of fault to see, where code has been modified as functions change.

The test returns 1, if the chip has a EUSART, rather than a basic USART.

Best Wishes

Thank you Ttelmah,

you have solved my doubts.
