In Topic: Nokia LCD + Arduino Ethernet Shield not working (together)

02 November 2011 - 01:56 PM

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?

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?

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.

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:

Anyone ever had this problem, even with different hardware?

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.
