UART Setup

[Suraj143]

Can somebody tell me how to configure the UART for 1200bps on 7bit data & even parity with start & stop bits.OSC is 4MHz.

Thanks

What PIC is it on?

You need to write some code to decide the parity bit.

Cant I use the UART module to receive data?

7bit data & even parity means is it 8 bit? so why I cant use the standard UART module & ignore the MSB that is parity bit in this case.

I want to do this with UART module.

Of course you can - as already mentioned, you would need to write code to handle the parity bit - check it, or discard as required.

Nigel thanks.

I still wondering what code do I need to write why can't i just ignore the MSB of the receive byte ?

So I need only to read the buffer.

You mean what code to write?

It's not like you need to write a lot

If you want to ignore the parity bit, then simply write code to AND it and mask that bit off. One line is all you need to add.

Thanks Nigel now I understood well.
