Netduino controls Syma S107

06 September 2011 - 11:51 AM

Hello community,
I would like to make from my netduino a Syma S107 IR transmitter. I found protocol description used for communication ( http://www.avergotti...controller.html ).I have IR Diode 940nm ( http://nettigo.pl/pu...273_LTE-302.pdf ) and i would like to connect it to netduino. Do i treat it as a normal diode ? I mean can i connect it with 200 ohm resistor for digital pins 2,3,7 ? Moreover if i would like to convert code from http://pastebin.com/raw.php?i=acigQFp3 do i need to use InterruptPin ? I see functions like those below in it this sample
cli();  // this turns off any background interrupts
sei();  // this turns them back on
and i don't know which functions in c# is equivalent .

Thanks a lot for your help.

Best Regards,
pater

LCD help

17 July 2011 - 11:28 AM

Hello,
Recently i connected my netduino to lcd as in tutorial here http://geekswithblog...id_crystal.aspx
Everything is ok except displaying letter "i" :/. LCD was bought here http://sklep.avt.pl/...yczny 16x2.html so documentation of it you can download here http://sklep.avt.pl/...f/LCD2X1605.pdf

And the problem generally is with letter "i" (EDIT : the same situation with capital letter "K"). When i display separatelly "i", it shows nothing. When i display word which contains "i" for example "milestone" letters to "i" are correct then rest are as strange signs - picture below. When i remove "i" from this word ("mlestone") everything is ok.

Word with "i"

Word without "i"

I am so confused so i would be appritiated for any help.

Regards,
Pater
