LCD on PortA PIC18F2525

#1 Post by AndAway » 14 Sep 2009 18:48

Hi Forum
Can I connect a 2x16 LCD to PortA? It has 6bits (0:6). What I mean is that there is no pin on PortA avaiable for R/W pin (which is not used, but in the LCD library it is stated that 'RW pin is configured as output and set to zero'.
To sum up will it work:
Lcd_Init(PortA);

You can use port A for LCD. You need to connect RW pin of your LCD to GND.

Hi Forum
Should I use Lcd_Init(PortA)? I have concerns about the default pin settings (it starts assigning pins from port.7).
Can I use this declaration:
Lcd_Config(PortA, 0, 1, 2, 3, PortA, 4, 5, 6??); <- what about the PortA.6
I use external oscillator so there is no RA6 or RA7.

You should use Lcd_Config and it is described and shown in mikroC Help how to do it.
