ADS1115

[DymDym]

hello!
Does anyone have a working code for ads1115 ?
(Proton PicBasic)...

[Pepe]

Demo with Proteus for ADS 1015(12bits)

[Pepe]

New version in post #2

[Dolci]

Hi Pepe,
 do you have a later version of Proteus for the demo file? Mine is V8.15. Thanks

I once had a working code like this:

But recently bought new ADS1115 does not want to work with it. I have a suspicion that I have ADS1015 instead of ADS1115.

Thanks for the code for ADS1015, I will try it!

If it is not in differential mode it makes no sense to ask if it is greater than 32767 to convert it to negative because in that mode it only gives positive values, also the $48 is wrong, there goes 0 if it is to read the conversion record or 1 if it is to read or write the configuration register

Hello all,
 I have a ADS1115 mbreak board module. according to the spread sheet the address is $90 when address is connected to ground. I'm using Pepe code and looking at the oscilloscope getting the ack = 0. what I'm missing is how you change the gain of the internal amplifier by manipulating the register. Is anyone has a full code for it? many thanks in advance.
Cheers
Yves

[Pepe]

example with variable gain

Les made a very flexible library for ADS1115 some time ago. Isn't that available somewhere on this web?

[Yves]

Thank you Pepe nice code and it works perfectly.

cheers,

Yves

[Pepe]

I'm glad my contribution was useful.

Hi Flossigud. Any Idea where Les flexible library is? Maybe Les may help. I don't need differential mode as I will have it tied up to ground

Cheers

Yves

It was probably on the old group.
