Adc For 16f88

[savnik]

I'm not clear on the problem you are having.

What is it doing or not doing? And what should it do instead?

I want to measure the audio input at the left and the right channel of a stereo coder (is for fm transmitter).
The left channel show on first line and the right channel show on second line on the 2X16 LCD.
But the LCD first show the left channel and after show the right channel alternately (very fast).

you may want to change the line:

LCDOut $fe,1,"L:"

to:

LCDOut $fe,1,$fe,2,"L:"

There's something obvious that just jump to my face. You're using the default LCD assignment, and this use a.0, a.1... which is also your adc channels.

so unless you forgot something in your copy/paste, or i totally misunderstood something

EDIT: one more... Assuming you're using the internal OSC, you want to configure it properly... unless the whole beast will run @32KHz

OSCCON = %01100000 ' 4MHz

Don't forget to check your maths range... sure it will overflow the max 100 soon.

I use external xtal 4mhz and the below LCD assignment

    DEFINE LCD_DREG PORTB		   
    DEFINE LCD_DBIT 4
    DEFINE LCD_RSREG PORTB		   
    DEFINE LCD_RSBIT 2
    DEFINE LCD_EREG PORTB		 
    DEFINE LCD_EBIT 3
    DEFINE LCD_BITS 4		      
    DEFINE LCD_LINES 2

Any idea for my problem;

[mister_e]

it worked fine here... sorry.

I think Kamikaze47 had the right idea, but mistyped it.

LCDOut $fe,2,"L:"
