#20102 Nokia LCD + Arduino Ethernet Shield not working (together)

Posted by Eduardo on 02 November 2011 - 01:56 PM in Netduino 2 (and Netduino 1)

Hello Arron Chapman, I thought it would not be necessary to ethernet shield, so I just changed the code. Anyway I tried different combinations with the lcd, changing cables and code but without success. Does the lcd and arduino ethernet shield can not work together at the same time? Is there a way to turn off the LCD when the shield is working and vice versa?



#19941 Nokia LCD + Arduino Ethernet Shield not working (together)

Posted by Eduardo on 28 October 2011 - 09:54 PM in Netduino 2 (and Netduino 1)

I'm a little lost, in the LCD driver the following pins are used:

    public Nokia_5110()
        {
            this.configNokia_5110(true, Pins.GPIO_PIN_D10, Pins.GPIO_PIN_D9, Pins.GPIO_PIN_D7, Pins.GPIO_PIN_D8);            
        }

        public void configNokia_5110(bool useBacklight, Cpu.Pin latch = Pins.GPIO_PIN_D3, Cpu.Pin backlight = Pins.GPIO_PIN_D9,
            Cpu.Pin reset = Pins.GPIO_PIN_D7, Cpu.Pin dataCommand = Pins.GPIO_PIN_D4)
        {
            ...

Then i tested the arduino ethernet shield in 5, 6 and 12:

SecretLabs.NETMF.Net.Wiznet5100 wiznet = new SecretLabs.NETMF.Net.Wiznet5100(SPI.SPI_module.SPI1, Pins.GPIO_PIN_D12);

But still giving error, anyone know what I should change?



#19922 Nokia LCD + Arduino Ethernet Shield not working (together)

Posted by Eduardo on 28 October 2011 - 12:23 PM in Netduino 2 (and Netduino 1)

Hello Stefan, initially both were in Pins.GPIO_PIN_D10 (standard in the examples for lcd and ethernet shield). I changed the lcd for Pins.GPIO_PIN_D6, then the above error occurred. Later I will change in arduino ethernet shield to see what happens.



#19892 Nokia LCD + Arduino Ethernet Shield not working (together)

Posted by Eduardo on 27 October 2011 - 10:27 PM in Netduino 2 (and Netduino 1)

Hello Stefan W., thanks for the reply, I changed the Pins.GPIO_PIN_D10 by Pins.GPIO_PIN_D6 (Board and code for lcd) but still no success, just remember that the LCD is the first initializing, see the error:

    #### Exception System.InvalidOperationException - CLR_E_INVALID_OPERATION (3) ####

Anyone ever had this problem, even with different hardware?



#19829 Nokia LCD + Arduino Ethernet Shield not working (together)

Posted by Eduardo on 26 October 2011 - 10:48 PM in Netduino 2 (and Netduino 1)

Hello everyone,

The LCD works perfectly with my RFID ID-12, and arduino network works perfectly with RFID ID-12, but when I try to use all together, or just the LCD and the arduino network, error occurs in:

SecretLabs.NETMF.Net.Wiznet5100 wiznet = new SecretLabs.NETMF.Net.Wiznet5100(SPI.SPI_module.SPI1, Pins.GPIO_PIN_D10);

I noticed that both use SPI.SPI_module.SPI1 and Pins.GPIO_PIN_D10, this could be causing this?



#19216 Problem with Arduino ethernet shield

Posted by Eduardo on 15 October 2011 - 03:59 PM in Netduino 2 (and Netduino 1)

Finally got it! After trying many things (changing the router, cable, and code) I did the only thing left, weld the ISCP again, I do not know what was wrong the first time but now it worked. I would like to thank Hari for put me on track, Earthed and Chris Walker who made suggestions in the post.



#17958 Problem with Arduino ethernet shield

Posted by Eduardo on 14 September 2011 - 01:21 AM in Netduino 2 (and Netduino 1)

Attaching the ISCP from netduino to the ethernet shield made me take a step forward, but still can not make a ping, when I ping the light of the ethernet shield RX flashes, but received no response. For this test I used the program from klotz MyFirstWebPage (I reach the code "listenSocket.Listen(1);"), also tried all the mac address indicated by Chris Walker. I'm out of ideas to continue, someone has gone through this?



#17775 Problem with Arduino ethernet shield

Posted by Eduardo on 08 September 2011 - 06:17 PM in Netduino 2 (and Netduino 1)

Reading this post I believe I have found the problem, according to the words of hari:

"You are using the new (revised) Arduino Ethernet Shield. You see those 6 odd headers on the bottom? They need to attach to pins on the Netduino. If you solder a 3x2 "ICSP" header onto your Netduino, you should be good to go. Otherwise, you will not get any response from the shield. Very few shield ever require these optional pins--but that one does."

I'll try to solder the pins of the two plates today. I return to report the result.



#17460 Problem with Arduino ethernet shield

Posted by Eduardo on 02 September 2011 - 09:26 PM in Netduino 2 (and Netduino 1)

Hello Chris Walker, this is my shield, I redo the test with Netduino on energy, apparently nothing has changed, with or without the power network and ON LEDs are connected, is it really necessary that I keep the card linked directly to energy ?

I pressed the pause and it appears in different parts of the routine
private byte ReadRegister(UInt16 address)
in class Wiznet5100, as if in a loop.

Hi Earthed, i think my shield work because he is in the driver topic;



#17414 Problem with Arduino ethernet shield

Posted by Eduardo on 01 September 2011 - 11:38 PM in Netduino 2 (and Netduino 1)

Could someone help me find where I am wrong?
I connected the shield in netduino, and the shield to my laptop (or router), but the program, in debug, reach the first line:

SecretLabs.NETMF.Net.Wiznet5100 wiznet = new SecretLabs.NETMF.Net.Wiznet5100(SPI.SPI_module.SPI1, Pins.GPIO_PIN_D10);


but does not reach the second:

NetworkInterface networkInterface = NetworkInterface.GetAllNetworkInterfaces()[0];

Project attached.

#15634 LCD Help needed, 16x2s are boring

Posted by Eduardo on 18 July 2011 - 12:59 PM in Netduino 2 (and Netduino 1)

*** OFF TOPIC ***
Eduardo, what it means your signature?...I understand only "The heart..."
Sound interesting!
Cheers


Hello Mario,

It is one of the most famous quotes by Blaise Pascal (Pensées book), I think in English would be something like
"The heart has reasons that reason cannot know."

Stefan you were much faster than I could wish, :o



#15416 Experimental Drivers for Wiznet-based Ethernet Shields

Posted by Eduardo on 13 July 2011 - 01:02 PM in Beta Firmware and Drivers

Hello Stefan, saving my life again, as you may have noticed I have asked questions in relation to RFID and LCD, if I connect the network card in netduino how I should connect the other components?



#15415 LCD Help needed, 16x2s are boring

Posted by Eduardo on 13 July 2011 - 12:58 PM in Netduino 2 (and Netduino 1)

Hello Stefan, thanks again for the help, I'll wait then.

Posted by Eduardo on 12 July 2011 - 10:06 PM in Beta Firmware and Drivers

Hello, I do not understand electronics and I'm starting with the development of netduino, I wonder if someone could tell me how to connect the Arduino Ethernet Shield in netduino with this breadboard.

Hello, I do not understand electronics and I’m starting with the development for netduino, I would like to know if you could tell me how to connect the LCD Nokia 5110 on the netduino with this breadboard.



#15081 Beginners Questions

Posted by Eduardo on 05 July 2011 - 05:36 PM in Netduino 2 (and Netduino 1)

Stefan thank you for answers, I think I will initially work with the lcd and the rfid, when these two are working, I decide which one to buy, the Netduino Plus or one of these shields.



#15045 Beginners Questions

Posted by Eduardo on 05 July 2011 - 12:27 PM in Netduino 2 (and Netduino 1)

Hello everyone and thank you for the answer, seems everything can be used together.
Stefan the protocol could be TCP.

One more thing, I thought that RFID and this LCD, what should I buy for the network?
What is necessary for everything to work together?



#15016 Beginners Questions

Posted by Eduardo on 05 July 2011 - 12:39 AM in Netduino 2 (and Netduino 1)

Hello everyone, I wonder if it's possible to have the in the same netduino, network, RFID and LCD components. I am a beginner and would like to do a project where the RFID send a message over the network, then receive a response that would be displayed.
