#60040 serial comunication between Netduino & PC

Posted by ferdinan on 08 September 2014 - 03:18 PM in General Discussion

Hi all,

I'm trying to set up the communication between my Netduino 2 and some TMP36 sensors installed on a machine.

I wanted to communicate with them through two XBEE modules.

I found several examples of code in C # but I need it in VB.

When I try to transcribe do not accept the definition of serialports.

the declaration I use is:

imports System.IO.Ports

UART serialports = dim as New serialports ("COM1", 19200, Parity.Even, 8, StopBits.One)

UART.Open ()

And the error I get is this:

"Type 'SecretLabs.NETMF.Hardware.Netduino.SerialPorts' has no constructor."

I hope you can help me because it is the last step in order to have a temperature control between the PC machine i.

#59501 Netduino Plus 2 - Remove Bootloader ?

Posted by ferdinan on 01 August 2014 - 10:18 AM in Netduino Plus 2 (and Netduino Plus 1)

After a week of putting my system temperature sensor with Netduino 2 in proper operation, and after using NET Micro Framework Tool Deploymennt several times I get the following response:

Pinging ... Error: No response from device
Erase ... Error: No response from device

The PC is properly detecting the device as in the device manager on the USB section as Netduino.

I have trying to enter to bootloader mode by pressing the button before connecting the board to the PC.
this means that:

continue to make noise connected device and the blue LED stays always on.
displays a message "windows need to install driver software controler STM32F2BOOTLOADER" and I can not find the file anywhere.
in the Device Manager menu appears as the STM32F2BOOTLOADER other devices.

seeing that this option not work have proven to steps he put into this post:

but does not reset the component when I connect the +3.3 V with the gold pin. besides that when I connect the SAM-BA not the virtual COM port appears to allow me to make tinnybooter.

I hope you understand my problem and you can help me.
but I'll have to waste valuable time returning the device and Istarting the system again: (

Hello everyone,

I will ask forgiveness for my English and I hope you can help me because I have a week completely stopped looking for a solution.

#59347 netduino2 & "unhandled type 'System.ArgumentException' in Mic...

Posted by ferdinan on 23 July 2014 - 11:58 AM in General Discussion

Hi,

I'm new to Netduino 2, I want to make a temperature control with VB and TMP36.

So I downloaded the toolbox. "NET Micro Framework Toolbox v0.2" and I'm trying the demo program. When starting it gives me an error saying: "unhandled type 'System.ArgumentException' in Microsoft.SPOT.Hardware.dll Exception" .

We are currently working with microsoft visual studio 2010 professional because we have a license, so I downloaded the following:

2.NET Micro Framework SDK v4.2

3. Netduino SDK v4.2.2.0 (32-bit)

here I leave the code I'm using:

Imports Microsoft.SPOT

Imports Microsoft.SPOT.Hardware

Imports SecretLabs.NETMF.Hardware

Imports SecretLabs.NETMF.Hardware.Netduino

Imports Toolbox.NETMF.Hardware

Module Module1

Sub Main()

' The Tmp36-sensor is connected to analog pin 4

Dim TemperatureSensor As Tmp36 = New Tmp36(New Netduino.ADC(Pins.GPIO_PIN_A4))

Do

Dim celcius As Double = TemperatureSensor.Temperature

Dim kelvin As Double = celcius + 273.15

Dim fahrenheit As Double = (celcius * 1.8) + 32.0

Debug.Print("Current temperature: " + celcius.ToString() + " celcius / " + kelvin.ToString() + " kelvin / " + fahrenheit.ToString() + " fahrenheit")

Thread.Sleep(1000)

Loop

End Sub

End Module
