My build.

[Ruben Wijnhoven]

I just bought this one:

Will that work to beceause it has no uln?

This relay can be used too but, maybe the noise "click click" will be annoying.

I am now working on the PH stamp. I have the latest one sayin ezo on the bottom left. Does this stamp need some changes in the code? I now takes about a minute for the board to completely boot. You get a lot of flashing images during boot. Then it boots up en shows ph. But after say 30sec it will reboot itself all by itself and do again the same minute boot sequence.

There is a code on the forum page for EZO stamps, just copie and paste over code on stamps tab.

[Ruben Wijnhoven]

That is what I did. But gives me above result.

[Christopher Kindig]

There are changes in other parts of the sketch as well, I'm not at home right now but I can look at mine and let you know what I find.

[Fernando Garcia]

Hi!

Your stamp is working with test code?

Best regards.

[Ruben Wijnhoven]

I will try tonight. I did find out they changed the baudrate from 38400 to 9600 with the stamps. So I will change serial3 to 9600.

[Fernando Garcia]

Did you sent this to your stamp?

Code: Select all

SERIAL,9600<CR>

What's the reason to change baud rate?

Why complicate your life?

[Christopher Kindig]

I did not think the baud rate affected the stamp?

[Fernando Garcia]

The baud rate need be synchronized otherwise never will work.

I mean:

Serial.begin() with serial monitor;

Serial3.begin() with stamp.

[Christopher Kindig]

Could that be why my PH stamp was giving some different readings sometimes.

Fernando,

In the webbased version serial3 get's intialised with 38400 in setup. So i should change that to 9600 no?

[Fernando Garcia]

To be more simple, NOT!

[Ruben Wijnhoven]

How do I solve it then? Any tips?

[Fernando Garcia]

Your code have this lines in Ferduino tab?

Code: Select all

#define STAMPS_V4X // Comente esta linha para usar Stamps EZO
//#define STAMPS_EZO // Descomente esta linha para usar Stamps EZO

[Ruben Wijnhoven]

Yes I also imported the changed stamp code you posted.

[Fernando Garcia]

Change to:

Code: Select all

//#define STAMPS_V4X // Comente esta linha para usar Stamps EZO
#define STAMPS_EZO // Descomente esta linha para usar Stamps EZO


[Ruben Wijnhoven]

For now changing the serial3 baudrate to 9600 seems to do the trick. I will now research on how to change the buadrate of the stamp form 9600 to 38400.

[Fernando Garcia]

Only set the serial monitor to carriage return and send SERIAL,38400
