#57405 Help on I2C

Posted by Frank Beerens on 07 April 2014 - 07:06 PM in Netduino 2 (and Netduino 1)

finally found someone to solder for me.

Now i connected the power supply from the netduino but the lcd does not turn on ?

Is the power of the netduinoe not enough for the lcd ?

oke thanks, i will order one of those displays. But do you have the source code for me for these displays ?

Which resistors should i use and which voltage for these?

thanks all for your answers.

i think i have to start from the beginning.

How do i connect the bus ? Which resistors do i need ? and can give someone me some example code to test if a can connect / communicatie with a slave ?

       OutputPort op = new OutputPort(Pins.GPIO_PIN_SDA, true);
            bool noton=false;

            while (true)
            {
                noton=!noton;
                op.Write(noton);
                Thread.Sleep(200);
            }

Hi Chris

i have a netduino 2 plus connected to SDA/SCL and one netduino 2 connected to A4/A5

The resistors are 4k7.

I another thread you where talking about testing with a led. I tried that also but maybe i did something but the led never turns on.

Pin 4 -> resistor 150 Ohm -> led -> gnd , i already turned the led from positive to negative but no result.

this is the code

Hi

i have a LCD display with I2C.

I tried for a few days now, but total no communication.

Is there a piece of sample code to test I2c ? Maybe ask the device adresses on the bus or something

thanks Frank
