Dosing pump error

[Roland Sorcik]

Hi Fernando!
Sorry for my very bad English

I use Ferduino English Master with Hungarian text...
All work fine,but metering pumps does not work!Like this topic :

viewtopic.php?f=24&t=314&hilit=metering
But in ferduino english this is the only:

//************************** Dispositivos SPI *********************************************
//*****************************************************************************************
const byte SD_CARD = 0;
const byte ETHER_CARD = 1;
const byte RFM = 2;
const byte ChipSelect_SD = 5;
const byte SelectSlave_ETH = 53;
const int ChipSelect_RFM = A15;

I changed ChipSelect_SD = 4; to ChipSelect_SD = 5; but still does not work!

Do you have any idea what could be the problem?
please help,thanks
Roland

Hi!

Welcome Roland!

1 - If the SD card is connected on ethernet shield it should be like this:

Code: Select all

const byte ChipSelect_SD = 4;           
const byte SelectSlave_ETH = 53;


If SD card is connected on TFT it should be like this:

Code: Select all

const byte ChipSelect_SD = 53;           
const byte SelectSlave_ETH = 4;


2 - Check if can work with this code:

Don't forget to change this variables according to your hardware.

Code: Select all

const byte SelectSlave_SD = 5;
const byte SelectSlave_ETH = 53;


3 - If this code doesn't work show me pictures with GOOD resolution and size to show your hardware and how it's assembled.

Check this topic to see how to do: viewtopic.php?f=27&t=173

Best regards.

Hi,
thanks for fast reply!
I have only one problem,my dosing pumps work in manual mode and also functions to calibrate,but in custom mode it makes no dosage.I just want it to work custom mode!
Some information from my system:

I dont have ethernet card. SD card slot is on TFT shield,but I dont have memory card(its problem?)....not important to me recording to memory card...

I test your first tip, and i say if it works.

update:
I tested,but not work..

Are you joking?

In this topic we are talking about SD card and text file all time and you ask me if it is needed?

SD card is MANDATORY to feeder, graphs and dosing pumps.

SD card should have 1 or 2 GB NOT more NOT less.

Sorry, is not joke.Only I did not know that
I could not find in local stores such a small capacity memory card.
I get one and try!
thank you!
