Proton PICBASIC vs MeLabs PICBASIC

For those wanting to do it with interrupts, download the Soft Uart for P12 by Warren Schroeder project from http://www.mikroe.com/en/projects/

It's an excellent tutorial as well as an interrupt driven full-duplex software UART. The code is quite simple and easy to follow.

Hi,

Full-duplex software UART is not possible or possible only if the baud rate
is very low and interrupts are used. (Software UARTs use bit-banging).

Soft Uart for P12 by Warren Schroeder:

If you look at the code you will see that RX uses an interrupt and that in
the SUB TX_19200 interrupts are disabled. This means that while
you are sending data you cannot receive data at the same time. (Not Full-duplex).

Best regards,

Luciano
