The application I have in mind is providing a voltage output in order to simulate a sensor. I have data sets, and I need to incorporate them into the microcontroller so that it can provide the simulated sensor voltages. What kind of memory do I need for this? Is this where EEPROM comes in? Or is there another type of memory for this? -- Jason Hsu http://www.jasonhsu.com/swrwatt.html http://www.jasonhsu.com/swrwatt-c.txt http://www.jasonhsu.com/swrwatt-asm.txt -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
