Make PICmiro as a voltmeter

[Ten Ten]

Does any one know where can i get good reference on making PICmicro as a voltmeter? I want to do project on on using a PIC to measure analog voltage to be displayed on a 2 x 16 LCD. Thanks!

Check my tutorials, the analogue one does just that - plus it sends it via RS232 as well.

Thanks, MR. Nigel.

I have another question. If i have a header file xx.H and i included it in a asm file and i found that the asm file wouldn't read the register declaration from the header file after quick build. What could be wrong? I am using MPLAB.


Error is
Error[113] D:\SOON CHIN FHONG\COPY OF PICPROJECT\LCD_ADC\LCD_ADC.ASM 254 : Symbol not previously defined (LOW_BIT_2REDA_5x7)

I never use MPLAB, so I can't comment on that, but with MPASM you simply use the 'include' directive.

However, it's only a few lines, just copy and paste it into place.

Ha! I have found the problem. It was a syntax error! I didn't set the mplab to be case insentive. So, it couldn't recognized when it was trying to read for the header file.

Thanks anyway.
