Is it possible to interface a Picaxe processor with a Basic Stamp?
The Picaxe uses between 3v and 6v as power source, How can I connect the Picaxe with a 0 - 3 v output with the Sasic Stamp which have a 0 - 5v input?
Since the Picaxe can be run at 5V, and you want to interface it with a stamp running at 5V why not just run the Picaxe @5V? If you cannot do this, then a comparison of voltage levels is required, taking a look at http://www.interfacebus.com/voltage_threshold.html·the stamp is 5V TTL, so its output should be 3.3V or .35V and its input must be >2V or <.8V. If the Picaxe is using CMOS levels, then you may be able to directly interface the two, but you need to make sure the output high of the stamp does not exceed 3.3V.
Ok the gritty details, for single direction signals, Picaxe to Stamp should be ok feeding it straight in, for Stamp to the picaxe, use a voltage divider to drop the voltage levels to the Picaxe. If its a bidirectional signal you should use this circuit http://www.interfacebus.com/Design_Translation.html#i
