ECIO40 ADC TO LCD 4 LINES

Hello, I'm trying to show ANO to lcd.
The simulation runs perfect, but real hardware just show me up to 2.495213V insted of 5V.
I use a 22k potenciometer connected to gnd and Vdd out. I read with multimeter AN0 and voltage goes from 0 to 5v, but in lcd jut I read up to 2,5V.
Vref votlage=0
vref optin=Vdd
conversion speed= fosc/64
aquisition cycles=1
Also I put ANO directly to VDD and then result is about 0.000V
Could you help me?

Hi ALOPEZ,
Welcome to the forums.
It will help us if you can post a flowchart, so we maybe able to help you.

Vref is normally in millivolts.
If using VDD as Vref then Vref = 500

thanks for you fast answer.
I'd try to attach a picture of hardware and also the fcfx file, but I can't find any bottom to attach files.
How I should do?
thanks

thanks for the patience.
here you have the proyect. I'll try to send a picture of hardware configuration in 250kb
thanks

Hi
Not quite sure what your asking, but i changed the flowchart as per martins post, and removed a raw enable call as it was already enabled flowchart attached

Hello thanks for you fast answer.
my goal is read voltage from AN0 (0v to 5v) in the LDC screen (4 line in the picture that i send).
In the flowcode simulation runs well (I can read in the lcd from 0v to 5v), but in the hardware maximum voltage that I read is about 2,5V when AN0=5V.
I try to open you fcfx file but I have an error, please see picture attached.
Thanks for you time.

Hello Alopez,
You will need to update to the latest version to open Dazz's example. The Help -> Check for updates should allow you to do this.

Hi
Follow what benj has said, if it still doesnt work, try the chart below, as sometimes its easier to strip out everythin but the basics etc

I still can't open your files with flowcode 6.0.2, see picture attach.
I guess is some issue with flowcode 6, I'll try with flowcode 5

The latest version is 6.0.3 Not 6.0.2
As Ben said, you can use Help menu, Check for updates.
Note: V6.0.4 is due to be released any day now.

Hi alopez
Ok i just tried the first chart i attached on hardware and its working fine
the chart i posted works fine, have you updated flowcode yet as we are on v6.3

Come on, is just a ADC conversion, whats wrong in the hardware?
I should be easy.

Doesn't work neither.
1-please send me the link where I can update to 6.0.3
2- how is possible that work for you with same hardware configuration?. I bought 4 ECIO40 and they are new. they are configurated in usb power supply.
3- remember simulation runs perfect is in the hardware where it fails, maximum can read is 511 instead of 1023.
Can some one help me?
thanks

Hi
Im using a different chip as it the board i have available, can you try something for me pls, using the chart you created from my last post, can you connect 5v directly to the an0 pin, note reading then connect an0 directly to 0v and let us know the readngs, update link above in davida post, edited my to to reflect this

readings 0 to 1023:
5V = 15
0V= 0
2,5V=511
I try 4 new ECIO40:
first: 2,5V=511
second: 304 all the time (0V;2,5V;5V)
third: flowcode can't detected
four: same than first 2,5V=511
