stm32 chips only support 400khz max i2c.

now take a breath and read your error.

'Microsoft.SPOT.Hardware.InputPort' does not contain a constructor that takes 2 arguments

 InputPort Inport1 = new InputPort(Pins.GPIO_PIN_D13, false);

has 2 arguments, and the error saiys it doesent want 2.

it wants 3.

public InputPort(Cpu.Pin portId, bool glitchFilter, Port.ResistorMode resistor);  

[font="arial, helvetica, sans-serif;"]SecretLabs.NETMF.Hardware.Netduino is for all gen2 boards, the other for the gen1.[/font]

[font="arial, helvetica, sans-serif;"]they changed the naming for the gen2 boards so its in line, all have the same namespace there (normal and plus - and the ones that will follow sometime too)[/font]

hmpf...

i dont think the netduino 1 has pwm on the led.

also only 4 pwm channs

(5,6,9,10);

so iam not suprised your code crashes

http://www.netduino....duino/specs.htm

a tutorial of how to convert 4.1 code to 4.2 (the different pwm, analog.. constructors) would be great. most tuts are for 4.1

i dont think that will work, not only that you have to write the

native drivers yourself, the pins it nuses have to be broken out also.

id go with a spi <> canbus ic

yeah i can imagine that beein very slow.

from what i know shieldbase uses uart (serial) to send the commands, and you send a lot of it, theres also error checking ans stuff i dont even know of i guess

next: netmf is interpreted, and its way slower than arduino, way way way.

the benefit  for sure it the nice ide and a managed and beautiful language, more ram and flash

i guess its: Debug.Print(new string(System.Text.Encoding.UTF8.GetChars(buffer)));

when you get the chars, it expects that the byte data is correct, now with serial the chances

are big that it isent (my experience so far)

if you send the data from a computer, print out there the byte data, and also on the netduino ( Debug.Print(buffer[0]); .. in a loop till buffer lenght) and compare them. it happened a lot for the data gets shifted and never syncronizes again

iam using cobs as packetframe, since that it never happened again

you can either flash the duino with netmf 4.3 firmware or set the output in vs2012 to 4.2

(on project -> settings)

edit: you find usefull information in the forums pinned on top.

4.3 firmware is here: http://forums.netdui...re-and-drivers/

iam 100% sure it works, for both the uart (com1) and the rs232 (com2) - ofc rs232 needs a max232 to convert voltage levels

(since i only have a mini, ill play around a lot with it )

you need a max232 to flash new firmware, the com1 is 12 volts, its not a good idea to connect your ftdi cable to there.

also, dont erase with 5 volts, that cant be good, use max 3.3v (i dont think its damaged, but it might get damaged if you do that)

or hook it up to your computers comput.

best is you read the guid again ... very carefully ...

2) why when i type the "SerialPort serialPort = new SerialPort("COM1", 4800, Parity.None, 8, StopBits.One);",

there are red line under the SerialPort.

you have to add a reference: Microsoft.SPOT.Hardware.SerialPort

maybe also system.io

and than using System.IO.Ports;

than your serialports will work.

sry i have no idea what todo, but ping and program running tells me its not damaged.

Int32 yourInt = Int32.Parse("122");

doesent work for single/double

edit: baxter is right, its working for double, but for Single i dont have parse
