View Full Version : Home built stamp question

08-03-2005, 02:37 AM
If I get the SX28AC chip from a local suplier and build the basic stamp module with the schematic supplied by parallax will I be able to program it with the Basic stamp editor?
Please help.

You will need to make sure that the SX 28 has our firmware installed or else it won't work. If the SX 28 has our firmware, you will be able to program it using the BASIC Stamp editor, provided the rest of your circuit is correctly built.

This means that any "plain vanilla" sx28AC chip from a vendor will NOT work. It MUST be a "special" sx28AC chip (called an "interpreter chip") purchased from Parallax, or from a reseller who originally bought it from Parallax.

The PBasic IDE environment depends on the BS2 (whatever flavor) having a run-time environment pre-burnt into a PIC or SX processor on the module. This run-time environment then loads your compiled PBasic 'tokens' (each PBasic keyword becomes an integer, basically) into the on-module EEPROM. The on-module PIC then reads the EEPROM and 'runs' (interprets and executes) your program.

The run-time environment on the PIC is Parallax proprietary, and without it, you won't have a BS2.
