Basic Stamp Voltage measurement

JimTheProgrammer

Is their a programatically based method of reading the input voltage to the BOE, such as the batterys that supply the power to the BOE? If not, I assume it requires some sort of circuit and would like to know how this circuit would be constructed.

Thanks,

Jim

Yes it does require a circuit. The same method used by the ANALOGIN command people are currently talking about in the SX forum should also work for the BASIC stamp, though you might have to adapt your own code for it:

Yes, use the RCTIME command.· You'll also need two resistors and a capacitor.· Check the PBASIC reference manual and Tracy Allen's page here:· http://www.emesystems.com/BS2rct.htm#B_voltage·· This method isn't super precise, but is cheap and easy to implement.· If you have one, an ADC and voltage divider could also be used.

Hope this helps!
