• Interfacing with a 24LC32 32K Serial EEPROM (I2C Protocol) - BS2

  A separate discussion deals with interfacing the 24LC32 with a PC's parallel port. This permits the designer to program a look up table or to upload data from a data logger. The uploaded data may then be analyzed using spreadsheet or other PC analysis tools.

• The PICAXE - A low cost alternative or adjunct to the Stamp

  

  The PICAXE-18X ($7.95) provides 2048 bytes of program memory, 256 bytes of EEPROM, a polled interrupt and much more and is comparable to the $49.00 Basic Stamp 2.

  The development software and documentation is free from Rev Ed. Programed using a Serial Port or USB to RS232 Converter. No special programmer is required.

  Use of a PICAXE-08M as a slave for PWM applications.
