Hi,

 

I am using Netduino Plus 2 and I followed the steps from 'Getting Started with Netduino' pdf on Chapter 5. I encountered few problems on the coding. There are 4 errors. Please help me!

 

 

 

Error 1 The best overloaded method match for 'Microsoft.SPOT.Hardware.AnalogInput.AnalogInput(Microsoft.SPOT.Hardware.Cpu.AnalogChannel)' has some invalid arguments

 

Error 2 Argument 1: cannot convert from 'Microsoft.SPOT.Hardware.Cpu.Pin' to 'Microsoft.SPOT.Hardware.Cpu.AnalogChannel'

 

 

Error 3 'Microsoft.SPOT.Hardware.AnalogInput' does not contain a definition for 'SetRange' and no extension method 'SetRange' accepting a first argument of type 'Microsoft.SPOT.Hardware.AnalogInput' could be found (are you missing a using directive or an assembly reference?)

 

Error 4 Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)

 

Looking forward to your speedy response. Thank you!

Hi and welcome to the Netduino forums!

 

The book describes the Netduino API, I think your problem would be fixed if you'd remove the reference to Microsoft.SPOT.Hardware.AnalogInput.dll and add a reference to SecretLabs.NETMF..Hardware.AnalogInput.dll

After following your instructions, there are more errors.. Anyway i am new to this Netduino Plus 2.. Could you please explain to me in detail? Thank you.

 

 

Error 1 'AnalogInput' is an ambiguous reference between 'Microsoft.SPOT.Hardware.AnalogInput' and 'SecretLabs.NETMF.Hardware.AnalogInput'

 

Error 2 'AnalogInput' is an ambiguous reference between 'Microsoft.SPOT.Hardware.AnalogInput' and 'SecretLabs.NETMF.Hardware.AnalogInput'

Error 3 The best overloaded method match for 'Microsoft.SPOT.Hardware.AnalogInput.AnalogInput(Microsoft.SPOT.Hardware.Cpu.AnalogChannel)' has some invalid arguments

 

Error 4 Argument 1: cannot convert from 'Microsoft.SPOT.Hardware.Cpu.Pin' to 'Microsoft.SPOT.Hardware.Cpu.AnalogChannel'

 

Error 5 'Microsoft.SPOT.Hardware.AnalogInput' does not contain a definition for 'SetRange' and no extension method 'SetRange' accepting a first argument of type 'Microsoft.SPOT.Hardware.AnalogInput' could be found (are you missing a using directive or an assembly reference?)

 

Error 6 Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)

Error 1 to 5 are probably because you only added the secretlabs reference but didn't remove the microsoft.spot.hardware.analoginput reference.

Now it has both options, which the IDE can't work with.

 

Error 6: without code it's difficult to help you out there!

Problem solved ! Thank you !

How was the problem solved? I'm facing the exact same problem now.

 

number 6 seems to be just a matter of changing int potValue=0; to double potValue=0;

I include the SecretLabs.NETMF.Hardware.AnalogInput command infront & add reference 'SecretLabs.NETMF.Hardware.AnalogInput..

 

eg:

SecretLabs.NETMF.Hardware.AnalogInput pot = new SecretLabs.NETMF.Hardware.AnalogInput(Pins.GPIO_PIN_A0);
