ECIO40 ADC TO LCD 4 LINES

[ALOPEZ]

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 votlage=0

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

[ALOPEZ]

here you have the hardware configuration.

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.

[ALOPEZ]

I don't know if is important but I'm using flowcode 6

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

[ALOPEZ]

here picture of version

[medelec35]

I still can't open your files with flowcode 6.0.2, see picture attach.

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.

Regards
Dazz

[ALOPEZ]

UMMMMMMMMM.....
where I have to donwload V 6.0.3?
From flowcode update menu I'm going to website where just I can get 6.0.2. see picture.

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

[ALOPEZ]

please find attach. simple software and adc config

[ALOPEZ]

potenciometer is 22k

Hi
Try the following,as you cant open my charts ive added an image ,worls om hardware here

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

Download 6.0.3 here:

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
Regards
DAzz

[ALOPEZ]

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
