Hi all,
I'm playing with a multiplexed LCD display that has 4 commons. The PIC that I'm using is the 16F1939. This PIC has a bunch of registers to set the segments in the LCD either on or off. Here are some of the registers,
LCDDATA0 SEG<7:0>COM0
LCDDATA1 SEG<15:8>COM0
LCDDATA2 SEG<23:16>COM0(1)
LCDDATA3 SEG<7:0>COM1
LCDDATA4 SEG<15:8>COM1
LCDDATA5 SEG<23:16>COM1(1)
LCDDATA6 SEG<7:0>COM2
LCDDATA7 SEG<15:8>COM2
LCDDATA8 SEG<23:16>COM2(1)
LCDDATA9 SEG<7:0>COM3
LCDDATA10 SEG<15:8>COM3
LCDDATA11 SEG<23:16>COM3(1)
What I'm trying to do is to define a variable that contains different bits from different registers. For example, I want to define the following variable
Can this be done using VAR or SYMBOL? Any ideas / comments?
Thank you,
Robert

Code:
DIGIT1.0 = LCDDATA0.0
DIGIT1.1 = LCDDATA3.0
DIGIT1.2 = LCDDATA6.0
DIGIT1.3 = LCDDATA9.0
DIGIT1.4 = LCDDATA0.1
DIGIT1.5 = LCDDATA3.1
DIGIT1.6 = LCDDATA6.1
DIGIT1.7 = LCDDATA9.1Thank you,
