/* * File: AD.h * Author: mdunne * * Software module to enable the Analog to Digital converter of the Uno32 boards. * All analog pins are are Port V and Port W, with an additional analog input for * the battery voltage (through a 10:1 divider). * * NOTE: Analog pins automatically take over digital I/O regardless of which TRIS * state it is in. There remains an error in the ADC code such that if all 12 * pins are enabled, one of them does not respond. * * AD_TEST (in the .c file) conditionally compiles the test harness for the code. * Make sure it is commented out for module useage. * * Created on November 22, 2011, 8:57 AM */#ifndef AD_H#define AD_H/******************************************************************************* * PUBLIC #DEFINES * ******************************************************************************/#define AD_PORTV3 (1<<0)#define AD_PORTV4 (1<<1)#define AD_PORTV5 (1<<2)#define AD_PORTV6 (1<<3)#define AD_PORTV7 (1<<4)#define AD_PORTV8 (1<<5)#define AD_PORTW3 (1<<6)#define AD_PORTW4 (1<<7)#define AD_PORTW5 (1<<8)#define AD_PORTW6 (1<<9)#define AD_PORTW7 (1<<10)#define AD_PORTW8 (1<<11)#define BAT_VOLTAGE (1<<12)#define ROACH_LIGHT_SENSOR (1<<13)/******************************************************************************* * PUBLIC FUNCTION PROTOTYPES * ******************************************************************************//** * @Function AD_Init * @param None * @return SUCCESS or ERROR * @brief Initializes the A/D subsystem and enable battery voltage monitoring. * @author Max Dunne, 2013.08.10 */char AD_Init(void);/** * @Function AD_AddPins(unsigned int AddPins) * @param RemovePins - use #defined AD_PORTxxx OR'd together for each A/D Pin you wish to remove * @return SUCCESS OR ERROR * @brief Remove pins from the A/D system.
