I found that was easier than I thought. You need always to send 2 bytes. If you send a command 0xYY you type: myDisplay.sendCommand(new byte[] { 0x80,0xYY }); If you send a data 0xYY you type: myDisplay.sendCommand(new byte[] { 0x40,0xYY }); It's all folks!!!

Ok, I managed to power it on and off. But things get more complicated. It seems that it understand a command only if you send it twice in the same connection i.e. - to power on I use myDisplay.sendCommand(new byte[] { 0xAF,0xAF }); - to power off I use myDisplay.sendCommand(new byte[] { 0xAE,0xAE }); public void sendCommand(byte [] command) { I2CDevice.I2CWriteTransaction writeTransaction = I2CDevice.CreateWriteTransaction(command); //execute transaction I2CDevice.I2CTransaction[] transactions = new I2CDevice.I2CTransaction[] { writeTransaction}; int transferred = 0; transferred = device.Execute(transactions, this.transactionTimeout //timeout in ms } and this is very strange.

It on 5V and I tried also 3.3V. Also I connected directly analog pins 4-5 to the screen without other resistors. I don't know if it is correct but I think that there are already resitors on the display.

I successfully ran my web client on the netduino+ for two days and an half.
It was sending correctly data to the server every 3 seconds during these days.
Then this morning, I noticed that the data flow interrupted roughly during the night for 8 hours.

The netduino got stuck during these 8 hours doing nothing.
I think that it got stuck on the HTTP call "(HttpWebRequest)WebRequest.Create(requestUri)" not even returning an exception!!!
I think this should be possible because a DHCP polling.

I forgot to say that to fix it, it was enough to unplug and plug again the ethernet cable. Without restarting the netduino+.
