#44232 Netduino Plus 2 network question

Posted by NooM on 26 January 2013 - 02:49 PM in Netduino Plus 2 (and Netduino Plus 1)

you should do:

 

 

while(NetInterface.IPAddress == "0.0.0.0")

{ Debug.Print("Waiting on DHCP..."); Thread.Sleep(1000);

-- get your ip here }  

 

mfg  




#44233 Configuration Management

Posted by NooM on 26 January 2013 - 02:53 PM in Netduino Plus 2 (and Netduino Plus 1)

i dont understand configuration manager, but you can store settings on sd card, and read them also..

 

when you keep the settings format easy - its also easy to read :)




#44277 Configuration Management

Posted by NooM on 26 January 2013 - 11:23 PM in Netduino Plus 2 (and Netduino Plus 1)

i like it :)




#44284 Is there any proper documentation for OneWire class?

Posted by NooM on 27 January 2013 - 04:32 AM in Visual Studio

0xBE and 0xCC is the data you write. its a byte in hexdecimal format.

 

when you have to read and write is descibed in the devices datasheet you wanna use, also what (0xBE for instance)

 

0xBE is 190 in decimal btw (a byte)




#44315 Trouble with the pins on plus2

Posted by NooM on 27 January 2013 - 07:14 PM in Netduino Plus 2 (and Netduino Plus 1)

yes, the last 2 messages say it.

 

i does not like Pins.yourpin -

it wants AnalogChannels.yourpin




#44508 HOW TO USE PUTTY

Posted by NooM on 29 January 2013 - 04:24 PM in General Discussion

YOU HAVE TO ENTER THE CORRECT SERIAL PORT AND RIGHT BAUDRATE IN PUTTY - THAN CLICK CONNECT

 

EDIT: MY KEYBOARD IS DAMAGED; CAPSLOCK IS STUCK - YOURS TOO??




#44509 problem in netdunio "Cannot deploy the base assembly 'mscorlib'

Posted by NooM on 29 January 2013 - 04:33 PM in Netduino Plus 2 (and Netduino Plus 1)

10.000 is quite a lot write cycles. iam now at about 1000-1500 in ~6 months, iam testing a lot of different stuff.

 

so when i keep programming that often, in 3-5 years its damaged :P

that is the best fun/price ratio ive ever seen.




#44596 ADC Breakout instead of AnalogicInput

Posted by NooM on 30 January 2013 - 12:01 AM in Netduino Plus 2 (and Netduino Plus 1)

iam using the mcp3201. its ok, but well.

 

my netduino has nearly no noise at adc.

iam powering it either from batteries or a stabilized wall supply, and i have some

capacitors on the power rails.

 

when i tried a cheap supply i got a lot of noise, maybe you should look there first

 

 

the benefit of an external adc is ofc you can supply 5v

and mini users like me can add an analog reference




#44625 NXTDuino, or damaged NXT brick?

Posted by NooM on 30 January 2013 - 05:36 PM in General Discussion

i dont think it will run, it has only half of the flash/ram than netduino has.

 

even if it will run, you dont have much flash/ram left todo anything with it.




#44931 Blown Netduini Plus2

Posted by NooM on 04 February 2013 - 10:49 PM in Netduino Plus 2 (and Netduino Plus 1)

you sure it blew up the duino?

more likly the converter is dead. the netduino can survice 12v. except you connect gnd to vin and positive to

to gnd-in -> that will fry your on board voltage converter and maybe the netduino chip itself




#44940 Installing Netduino drivers for STM32 F4 series(with STM32F407 MCU)

Posted by NooM on 05 February 2013 - 04:00 AM in General Discussion

nope, netduino firmware doesent run on discovery board cos it has a different oscillator (you can solder a different one tho)

 

also netduino is the 64pin version of the chip, while the discovery is 100 pin iirc.

 

 

but there is hope: codeplex has a stm32f4 netmf site where you can get the firmware for the discovery board.

it actually works pretty well, except the spi ius bugged and doesent work correctly with to low frequenzy (2mhz+ is fine)




#44950 Blown Netduini Plus2

Posted by NooM on 05 February 2013 - 08:08 AM in Netduino Plus 2 (and Netduino Plus 1)

yeah, someone should buy me a plus2 so i get familiar with those too :P

 

my mini isent protected like that :(




#44951 Measuring square wave frequency when it's an input

Posted by NooM on 05 February 2013 - 08:52 AM in General Discussion

i dont think you can measure that kind of output with an netduino  (cos of the speed the pins are read)

 

but you could add an capacitor and measure the voltage - than calculate the light intensity from that

 

edit: that would only work if the duty cycle changes ofc :(




#44957 Measuring square wave frequency when it's an input

Posted by NooM on 05 February 2013 - 11:30 AM in General Discussion

just to add: when doing a simple framecounter i get around 1200 updates per second on the mini, and ~8000 on the stm32 versions

- but thats without any other code running




#45002 how to stop the socket.connection

Posted by NooM on 06 February 2013 - 09:46 AM in Netduino Plus 2 (and Netduino Plus 1)

i am not sure about 4.3, but in 4.2 its blocking - means nothing happens till a connection is etablished.

 

you may want to put it in a thread so your programm keeps running, same for receiving data




#45040 how to stop the socket.connection

Posted by NooM on 06 February 2013 - 10:52 PM in Netduino Plus 2 (and Netduino Plus 1)

netmf doesent support async, so threading _IS_ the best solution.

on windows async would be the best (well, even that is some kind of threading ...)




#45057 mIP and COSM

Posted by NooM on 07 February 2013 - 05:13 AM in General Discussion

still noone has some code?




#45061 Safe Way to power netduino with 5v Regulated Supply

Posted by NooM on 07 February 2013 - 07:05 AM in Netduino Plus 2 (and Netduino Plus 1)

first: it doesent matter if its 5 or 9 volt, when you would actually connect that to usb your usb port would be damaged.

 

than: iam very very sure the netduino does have a protection for that, so that you can power it with a 7.5 to 9v power supply and still have it connected to usb




#45063 Powering the Mini with 3.7v

Posted by NooM on 07 February 2013 - 08:06 AM in Netduino Mini

yes that works.

 

iam using a LM2577 (from ebay, very cheapo) to step up to 5v for powering the mini (i can be powered by regulated 5v) ..

than iam using a LM2596 to step it down to 3.3v for all rails/devices.

 

iam also using bluetooth.

you may have a look at those: http://www.ebay.at/i...=item3a7423a9cd

 

 

the sparkfun ones seem quite pricy




#45140 I2C on Netduino 1 not working

Posted by NooM on 08 February 2013 - 07:59 AM in Netduino 2 (and Netduino 1)

that doesent look right:

new I2CDevice.Configuration(1, 1);

 

wich device it is? name

 

and what about pullups on i2c lines?




#45142 I2C on Netduino 1 not working

Posted by NooM on 08 February 2013 - 08:17 AM in Netduino 2 (and Netduino 1)

iam using 4.7 kilo-ohms, they work well.

 

hm, havent found a good datasheet for that :(

so no idea what the i2c address is.




#45183 Issue with resolving AnalogInput

Posted by NooM on 08 February 2013 - 10:52 PM in Netduino Plus 2 (and Netduino Plus 1)

its not Cpu.AnalogChannel.ANALOG_2 - its AnalogChannels.Yourpin

- netduino has a definition for that. in: sl.hardware.yournetduino




#45184 Hydra Power Supply on Kickstarter

Posted by NooM on 08 February 2013 - 10:58 PM in General Discussion

in my opinion that would be a total waste of money.

its design is simple: a small chip for bluetooth and settings .. than maybe a step up converter-

than 3 step down converters with digital mpotentiometers (so you can control the output voltage per software)

 

its like a arduino chip with step up and step down converters... total cost: 20€

 

edit: http://imageshack.us...me214092012.png

simple version of it ... add another step up to 24v .. another step down.. replace the blue

pots with digi-pots, add a small chip.. done :P




#45203 can N+2's firmware runs on a 144 pins STM32F405 chip without any code cha...

Posted by NooM on 09 February 2013 - 12:35 PM in Netduino Plus 2 (and Netduino Plus 1)

i think so, yes. the crystal has to be the same frequenzy.




#45223 Convert a string to an integer

Posted by NooM on 09 February 2013 - 11:50 PM in Netduino Plus 2 (and Netduino Plus 1)

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
