Hi, I have got an atlas scientific ph stamp and a generic ph probe and was wondering if anyone has used one of these with the netduino before and how I would go about taking ph readings with it? http://www.atlas-sci...Arduino-ph.html Cheers andy

Do you own already a Netduino? Or the problem is to be sure the stamp is working correctly with a Netduino, so you'll going to buy one? I think should be working. The only doubt is about the serial speed: 38400bps. If you own the Netduino, the simplest thing is to try right now. Cheers

Hi Yes I already have both the stamp, a probe and a netduino, just not sure being very new to all this what I need to do next. I am happy connecting it up but am not sure how to write a script from scratch to read and interpret a serial device. Also can I'm not sure if or how I would go about making temperature referenced ph readings. I've got my ds18b20 working, but I am pretty sure with ph you have to compensate for temperature? Can the netduino deal with a baud speed of 38400bps? Also how can I multiplex the serial pins, I have some serial registers 74hc59n, but not sure how to connect them up. I am using pin 3 for my sparkfun serial graphics lcd and pins 0 and 1 for my ds18b20 (I also want to add more ds18b20s eventually). Thanks for your help, Andy

Please provide me with a code to link a pH stamp and a PIC 16F877A
