WORD ADC (  BYTE  channel  )

execute A/D conversion for specific input channel Reads the voltage from the specified input source and does a standard conversion. A reading of 0x0000 implies +0V while 0x03ff implies +5V Parameters: channel  0-7 the A/D channel we want to measure (corresponds to a pin number) Returns: conversion result as a 16Bit value Definition at line 29 of file adc.c.

void ADC_init (  void   )

initialize A/D hardware The A/D converter of the T89C51CC02 is initialized to use P1.0 and P1.1 as analogue inputs. A standard conversion (see T89C51CC02 datasheet) is used. Definition at line 13 of file adc.c. Referenced by main().
