README: PCB-Based Capacitive Single Touch Sensing with MSP430 Application Report (SLAA363)
Released 6/18/2007
Version 0-01: 1st revision (Sterzik)

This readme.txt file describes the usage of the information contained within the .zip archive
downloaded with the application report mentioned above.

***APPENDIX A***
Appendix A SCH RC&RO 20xx Eval Demo.pdf - Schematic for test hardware described in the application report.
Two systems are implemented in a single schematic: Relaxation Oscillator (RO) & Resistor/Capacitor Charge/Discharge (RC).

RC Software:
msp430x20x1_RC Keys.c - Implements simple 4-button detection. Each key turns on or off the two LEDs in combination.
msp430x20x1_RC_TA_UART Slider.c - Implements a 64 position slider. Position data is output off-chip via Timer_A UART TX.

RO Software:
msp430x20x1_RO Keys.c - Implements simple 4-button detection. Each key turns on or off the two LEDs in combination.
msp430x20x1_RO_TA_UART Slider.c - Implements a 64 position slider. Position data is output off-chip via Timer_A UART TX.

***APPENDIX B***
Appendix B SCH Simple 20xx RC Demo.pdf - Schematic for simple 4-button demo hardware for use with the EZ430 FET. (Also giveaway at 2007 MSP-430 Day)
Measure_VLO_SW.s43 - VLO measurement subroutine for accurate wakeup timing.
msp430_Day_4_Key_Demo ver0-09.c - Source code for simple 4-key demo driving LED at different strengths for each key (include Measure_VLO_SW.s43 source)

(All software is built and tested using IAR Kicstart Version 3.42)
