Coding Smackdown

Great News! Just ordered 2 from Amazon! Now my Brew System won't be so overtaxed with the PID and Web server running together. Can't wait to get them and put in my controller box.

You need to add a reference to SecretLabs.NETMF.Hardware.AnalogInput and that should get you what you need. Hope this helps.

My Netduino based Brew Controller uses both interrupts and threads and would probably be a good example for you to see one way of doing things. I use interrupts to handle the main panel buttons and I use threads to handle the various services; temperature monitoring, mash profile, web Server, Internet Time Service and NETBIOS Services. You can find the complete code over at https://github.com/l...yBrewController Hope it helps.

About a year back I wrote some basic code to print on network receipt printers. The biggest issue I had was all of the example code was too big for the Netduino. I end up sending basic text and ASCII commands to the printer, but never got what I was looking for. Now With .Net 4.2 you might have enough memory to do it. Its double almost since last time i tried. Good luck!

You are correct about the bounce being a voltage fluctuation. The other part is how the Netduino determines an edge change from low to high. As I understand it, The Netduino will look at voltages below 1.6V as a logic low and those above as a logic high. So if your trace isn't showing a pronounced bounce it could be that the signal is varying just enough to be seen as fluctuating from low to high causing the Netduino to trigger the interrupt multiple times. Hope that helps
