In Topic: Powering Netduino Plus 2

Ok.

Thanks for the help. If I understand it right it is not recommend to power the NP2 via the 5V pin. So I think I have find a alternative to powering the NP2. I find several boards that are able to pull up the voltage. So I will take the 7.2V of the accu pack an pull it up to 9V and connected that to the connector barrel of the NP2. This boards only costs 4-5€ so I think thats a save solution.

Hy sjmill01,

thanks for your answer. Do supply the barrel connector with a 7.2V accu pack or with really 7.5V ? Because my Problem is that i have only 7.2V or 5V. 


In Topic: I2C LCD not working on Netduino Plus 2

I use the NP2 and the V4.2.2.2. If I get it right, I have to use a pull up resistor on both wire to the positive potential. The I2C Output is 3.3V . Can i connect the pull ups to 5V or is it still better to connect the resistors to 3.3V ? ******* I just found a thread in the board that answer my question. So i think the Outputs are in the Open Collector mode and so the high signal must generate via pull up resistors. So I can pull up to 5V. I think this must be fine

So I have make still some test. But I didn't get the right IP-Adress from the NetworkInterfaceClass, when didn't debug the netduino. Does anybody made a same experience with the this class ? Is the NP1 in the debug mode in the TinyCLR. Or is where a problem to get the right adress in the TinyCLR. Or does anybody have an another idea to the renew the address when DHCP failed during power up the system ?

I am not sure but I think there is a bug: 

Sub main()

While True

 If (Eth0(0).IPAddress = "192.168.178.33")) Then   Onboard_LED.Write(Not Onboard_LED.Read)   End If

  Thread.Sleep(1000)

End while

End Sub

When I debug the netduino the LED is blinking. When I stop Debugging and reboot the NP1, when the LED is not blinking but I can ping the Netduino with the IP Address 192.168.178.33. Thats strange I think or not ?
