Data converions?

edmondfox

I have written a windows interface to send data to the stamp over the serial port, however I can only get the data to be sent as an array of characters, not integers like the stamp expects. Do you have any ideas what I can do on the stamp side to take this data and convert it to the proper form so that stamp can use it to run the motors?

Can you give me an example of the array the Stamp is receiving?

There is a VB program attached to the product page of the RS-232 DCE AppMod that shows how the Stamp can be setup to receive bytes, words, or even strings.· The Stamp just needs to know what's coming so it can get ready.

In the windows program I am sending data to control a stepper motor as an array of characters. An example of what would be sent is "+" then "100" then a space, then "+" then "100" then a space, then "1"(ie. +100 +100 1 but sent in sections as I specified). I decided to send them seperately because I thought it would make it easier. However I would like the stamp to interpret the 100 as the number 100, not as a characters. Will storing them into the onchip memory allow this conversion?

This article explains everything you need to know -- though you'll have to adapt the techniques for your specific application.
