Hi everyone,

 

I have a Netduino Plus and a TMP36 temperature sensor.

My code already worked perfect with firmware 4.1:

using System;using System.Net;using System.Net.Sockets;using System.Threading;using Microsoft.SPOT;using Microsoft.SPOT.Hardware;using SecretLabs.NETMF.Hardware;using SecretLabs.NETMF.Hardware.NetduinoPlus;namespace TemperatureSensorTest{    public class Program    {        public static void Main()        {            //Temperature sensor                       var voltagePort = new AnalogInput(Pins.GPIO_PIN_A1);            var lowPort = new OutputPort(Pins.GPIO_PIN_A0, false);            var highPort = new OutputPort(Pins.GPIO_PIN_A2, true);                       double rawValue = voltagePort.Read();            double result = ((rawValue - 0.5) * 1000) / 10;            Debug.Print("Result: " + result);        }    }}

Now, it doesn't work with my new firmware. Would you please let me find a solution for this problem?

 

Thanks in advance,

Mohammad

Can you tell us more?  Saying "it doesn't work with my new firmware" is very vague.  What part does not work? Does it not get a reading?  Is the temperature incorrect?

Also, I'm just guessing here, but with .NET Micro Framework 4.2 there are new "AnalogInput" classes. So you'll want to be sure to pull in "SecretLabs.NETMF.Hardware.AnalogInput.dll" as a reference in your project. And then type "SecretLabs.NETMF.Hardware.AnalogInput" instead of just "AnalogInput" when you create your class instances. Chris

Hi Dave and Chris,

 

The problem was solved by the aforementioned link in my second post in this thread (http://forums.netdui...nal-to-digital/). So, thanks for your attention to my problem.

 

Cheers,

Mohammad
