Split a byte

[EA7-JFV]

Hi,
It's possible split a input byte?

I need 8 input lines to input a byte, but I need split the byte, for input in two different ports:

Something like this:
bit3, bit2, bit1 and bit0 --> inputs in Portb.3, Portb.2, Portb.1 and Portb.0
and
bit7, bit6, bit5 and bit4 --> inputs in Portd.7, Portd.6, Portd.5 and Portd.4

Its possible to do something like that?

Thanks

Hello,

Do exactly what you describing.

someByte = 0b10101010

PortB = ( PortB and 0xF0 ) or ( someByte and 0x0F)  // Get existing port, get upper nibble  then OR lower nibble
PortD = ( PortF and 0x0F ) or ( someByte and 0xF0) // get lower nibble OR with upper nibble

Oh Great!

Mmmm... it's so simple... and bright!

Thanks, so very much, Anobium

The libraries use this as the method for LCD and GLCDs.

Good luck.
