LCD BARgraphs

[ciberman37]

The compiler signalise error in line 29, no is alabel?

[Darrel Taylor]

Line 29 is GOTO overBAR, and overBAR: is the last line in the include file.

Check the end of the file and make sure overBAR is there. If not, you may have received a partial download. Try downloading it again.

What kind of licence did u put on your code Darrel ?

I currently making a little project for a contest in a swedish electronics forum, and I really would like to use a LCD bargraph, and the rules states that I only can use includes that are "GPL or more free.", can I use this, or do I have to write something much more ugly myself ?

As long as you don't say you wrote it ... you can do whatever you want with it.

For Free!

Hi darrel.. Really nice work.Congrats.
I intend to write lcd bar vu-meter and bar voltmeter codes. I did for voltmeter but not for bar vu-meter. And I need help for this. MCU is 16f876 and 2x16 lcd.. I need some help to convert reading from frequency to the bars. Can you help me ?

[Darrel Taylor]

For VU-Meter, I think you'll need an external LOG convertor such as one of these op-amp circuits ...

Without the LOG convertor, you'll only see big peaks in the bargraph and none of the lower level signals.

If you're thinking of a Spectrum Analyzer, then nope, can't help there.

Also thanks to Alain, the CA3089 and NE604 can do the job very nice!

I use the Bargraphs(lines) to show on lcd the volt from 0 to 5 volt with adc 10 bit.
How to change the code to show always at first Col the first character.
Like this : from ||||| to show only | if the volt is 0.
