Dear all, I'm a researcher from University of Coimbra, Portugal and I'm developing a prototype to measure a specific property. However, this property is not covered by any provided sensor board, and I had to make a custom circuit. I'm using the micaz motes from Crossbow, with TinyOS-2.x and 6lowPAN.
My problem now is the connection between the Vout (from my custom circuit) and the micaZ mote. I'm trying to use the prototyping area from a MDA100CB sensor board. I already defined the ADC4 (the free interface 12-F from mda100cb) to connect my circuit and developed a nesC application, too. I developed yet, an application for the custom sensor board, based on the provided for basicsb, mda100, mts300..., chanching only the adc port. When I turn all my devices on, if I measure the the Vout of my circuit with a multimetro it is constant, however if the value is read through the micaz it doesn't make any sense, which leads me to believe that the problem is in the nesC application. So, how should I read (tinyos-2.x) a non used iterface (ADC2..3...4....anyone)? (Until now I have always used the basicsb or mda100, which provide me the DemoSensorC...PhotoC...TempC, etc.) How do I connect a custom circuit to the mda100cb prototyping area? (I think that I just need to connect the Vout to the ADC interface, but I'm not sure) I hope someone can help me. Best Regards, Ricardo Silva
