Silly n00b question - digitalWrite(pin,HIGH) to Gadgeteer

[mhectorgato]

I’m porting an Arduino lib to NETMF/Gadgeteer

The original code:

digitalWrite(resetPin, HIGH);

My code:

var p3 = GT.Socket.GetSocket(9, false, null, null).CpuPins[3];
var ResetPin = new OutputPort(p3, false);
ResetPin.Write(true);

Essentially the question is – does the HIGH == true && does LOW == false?

yes

Thanks for the info.

My first attempt for extending my Arachnid. As the project proceeds, I’ll put up more info.

@ mhectorgato - Is that what i think it is?

@ danmeland - Start a new thread with your question.

So, say I had a clk, a cs, and a msio.
And inorder for the msio to transmit, I had to push clk and cs low.

would that mean?

var p3 = GT.Socket.GetSocket(9, false, null, null).CpuPins[3];
var p4 = GT.Socket.GetSocket(9, false, null, null).CpuPins[4];
var ClkPin = new OutputPort(p3, true);
ClkPin.Write(false);
var CsPin = new OutputPort(p4, true);
CsPin.Write(false);
WriteRead(bytes, bytes);
CsPin.Write(true0;
ClkPin.Write(true);

Is this right?

BTW running on a kind of SPI.

Thanks

I would tweak that a bit and change…

var ClkPin = new OutputPort(p3, true);
ClkPin.Write(false);
var CsPin = new OutputPort(p4, true);
CsPin.Write(false);

to

var ClkPin = new OutputPort(p3, false);
var CsPin = new OutputPort(p4, false);

Otherwise, you’ll end up with a momentary state where it flips from a default value of true to a value of false.

@ mhectorgato - Nice one, i expect you to be whipping out Eagle and superseeding the v1 design
