PB ethernet when ugrade to new Ferduino code

[Sueur Aurelien]

Hello Fernando, it's been a long time since I came. You have done a good job since and I congratulate you!
I have just updated my Ferduino mega but I have a problem with ethernet yet I have:

Code: Select all

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 byte ChipSelect_RFM = 69;

In debug it does not return the correct ip and MQTT does not connect!

Can you help me ?

[Fernando Garcia]

Hi!

Don't change this part of code.

For Ferduino Mega you should only comment this two lines:

Code: Select all

//#define USE_PIN_4_FOR_SD_CARD
//#define USE_PIN_53_FOR_SD_CARD

Problems with wrong IP are normally related with SD card, try format it as FAT.

Best regards.

i was making too many changes on your code for adapt to my installation.

i restart to your original code and it's ok now. but sometimes the "webcontrol" website say me "Your controller is not responding".

[Fernando Garcia]

Hi!

I think your controller is disconnecting from server (broker) continuously, look for serial monitor.

Maybe there some problem with electric noise in your power supply making the W5100 not working correctly.

Best regards.

Hi, thank you for your reponse, but i have an IBM serveur power supply and with your old code on JOY REEF it worked well

At the start up, it's connected and after failed:

Code: Select all

Do you still think of power supply or see something else?

[Fernando Garcia]

Hi!

Yes, I think it's problem with power supply.

Try power the board only with USB cable to see what happens. Maybe the voltage won't be enough to make the RTC work.

Best regards.

HI!

You were right, but after unplugging the + 5v wire of my Ferduino, he briefly touched the 12v and my Ferduino flashed!

I managed to restart it but the time and date is incoherent and even after tuning I changed the DS1307 IC but still the same

Do you have a new and good idea?

[Fernando Garcia]

Hi!

As I told the RTC won't work with low voltage.

Try a power supply with more than 7V.

Best regards.

[Sueur Aurelien]

Hi Fernando, it is the + 5v general card and not the 7v-9v power supply which touched the 12v very briefly.

Now the RTC Ds1307 no longer responds even after replacing the integrated circuit.

Did you get an idea, or my ferduino board died?

Best regards !

Hi!

You don't understand what I'm talking.

When there a 5V power supply connected to power plug the voltage drop around 4V then the RTC doesn't work.

Try the test code to scan I2C devices available on forum.

Don't forget to move the RTC jumpers to position 2-3 (pins 20 -21).

The address should be 0x68 for RTC and 0x20 for PCF8575.

Your board is not damaged I think was not needed replace the RTC.

Best regards.

[Sueur Aurelien]

I understand what you say but I do not power the card with the power plug but directly on the + 5v

When use the I2c scan i read that on monitor with jumpers on 2-3:

Code: Select all

Scanning...
I2C device found at address 0x20 !
done

[Fernando Garcia]

So the RTC is not working.

[Sueur Aurelien]

Hi Fernando !

installed the module DS3231 as you advised me and it works well, but my wiznet chips work very bad even with 5v by USB.

I have ESP and i buy a logic level converter quickly.

[Fernando Garcia]

Hi!

Try add an electrolytic capacitor of 15 uF or less to 3.3 V circuit to reduce the noise.

The 3.3 V regulator is IC16 next of wavemaker connector. See here: http://ferduino.com/wp-content/uploads/ ... a-2560.pdf

The tab is the positive.

The problem to make ESP8266 work with Ferduino Mega is the serial port.

Serial 2 is used for stamps, maybe with the library SoftwareSerial you can emulate a serial port using 2 free pins.

I haven't tested it.

Best regards.

[Sueur Aurelien]

Hi Fernando!

I tested a capacitor of 10µF on 3v3, but it's same.

Now it worked with esplink waiting for you to make new Ferduino board.

[Fernando Garcia]

Hi!

I'm sorry for it.

Are you using softwareSerial library or serial 3?

Best regards.
