14 / 60 page ![]() 2001 Microchip Technology Inc. DS30374D-page 9 PICDEM 2 USER’S GUIDE 12 Chapter 3. Tutorials The tut.asm tutorial program is pre-programmed into the sample device. This program is listed on the included 3.5” program disk for user reference. I.e., if the sample device has been reprogrammed with another sample program, the tutorial may be reassembled and reprogrammed into the device. The tutorial program functions as follows. Pressing the switch S2 causes the LEDs to binary count up to FFh (255 decimal). Past FFh (all LEDs on), the count rolls over to zero (all LEDs off). The program may be reset by pressing the switch S1. For detailed information on the PICDEM 2 hardware, please refer to Appendix A.
