converting analog to digital Temperature
I am trying to design a circuit using basic stamp to convert analog temperature to digital temp. Does anyone have any similar projects or can guide me in the direction I should take to accomplish this
You need to provide more information. There are all sorts of temperature sensors. Some of them produce a voltage proportional to the temperature (
like the LM34
). Some of them internally convert the temperature to digital and the Stamp reads the digital information from the device (
like the DS1620
). The StampWorks Kit includes a DS1620 and there's a manual and source code available for download off the product's webpage. There's a
Nuts and Volts column
(#2) on temperature measurement. In the same collection, #29 shows how to use the LM34 with an ADC0831 analog to digital converter.
Using a thermistor or an AD590 would allow you to use the Stamp's RCTIME command to do the analog to digital conversion. I have examples for the Stamp posted on my web page at
I'm using the BS2 with the lm34 and the ADC0831. I am having problems with the code for the ADC0831 to display
Here is a pointer to
the parallax textbook.
Re-inventing the wheel is not a waste of time if, when you are done, you understand why it is round.
