#5794 Serial Communication via D0 and D1

Posted by bill.french on 06 December 2010 - 02:50 AM in Netduino 2 (and Netduino 1)

OK I figured it out... I was receiving 4x more bytes than expected because the onewire->rs232 works in a completely unexpected way. Even once I disconnected the device, the uart still had data in it. So, when I ask it to read a byte, it returns the byte represented in hex using ascii characters... So, if I was expecting just this byte: 11111111 (in binary) (255 in decimal) (FF in hex) it actually sends the ascii character F twice followed by linefeed and carriage return, for a total of four bytes.

#7636 Question about COM2

Staring at Tecchie's Pinout Cards tonight, a question popped in my head:

If you are using COM2, are D7 and D8 (rts/cts) unusable for anything else? Or can the still be assigned as input/output ports?

I'm using this for my sous vide controller: (i use a transistor to control it from the netduino)

What are you working on?

Can anyone recommend a vendor for sensors?

Welcome!! What kind of sensors???

#8170 LEDs for netduino

Posted by bill.french on 23 January 2011 - 02:39 PM in General Discussion

You can use a plain old NPN transistor, which is fun to use if you want to learn about transistors, anyway. I've used various leds with 220ohm resistors on various ports without and problem so far for testing, but your mileage may vary! I'd like to find a source for leds with resistors built in.
