Two inputs to Portc

[slahiri]

I have two inputs I need to send to PORTC. 1st input needs to go on 1st 4 bits and 2nd input needs to go next 4bits. How can I do that. Should I use output_portc(value) and send it twice or there is other way of doing this.

Here is one such example:

data1 = 0x03;
data2 = 0x02;

temp = (data2<<4)&(data1&0x0f);
PORTC = temp;

It seems like you're describing an LCD interface.
See the CCS example file, LCD.C, which shows how
to define several bits as a element of a structure.
Then you can write to those 4 bits with one line of code.
The LCD.C file is in this folder:
c:\Program Files\Picc\Drivers
