[Flashforth-devel] write to BPP-420 from mega2560?

[Phoenix R. <pho...@pl...>]

Hello,

I'm having trouble figuring out how to invert the serial data in order 
to write to this Scott Edwards display.  All that comes out is 
gibberish.  Is there a method using Flashforth that will yield a similar 
result that 'softwareserial' does with its 'invert' bit?

Thanks!

Hi,
I don't think so. There is no setting in mega2560 for the UART to invert 
the voltages.

There was no link to in your message.
Some of the Scott Edwards displays support both polarities of the 
voltages.
