ADC

This library provides the functions for initializing the adc and to get the raw adc values. In case of AVR/PIC/ARM or other high end controllers the inbuilt adc is used. In case of 8051/8052 as it doesn't have an inbuilt adc, ADC0809(8-bit) adc is used.

ADC_Init

{{#Widget:LibTable}}

Defination	void ADC_Init()
Input Arguments	none
Return Value	none
Description	This function initializes the ADC module.
Usage	void main() { ADC_INit(); }

ADC_GetAdcValue

{{#Widget:LibTable}}

Defination	uint16_t ADC_GetAdcValue(uint8_t channel)
Input Arguments	uint8_t(channel number).
Return Value	uint16_t(10 bit ADC result)
Description	This function does the ADC conversion for the Selected Channel and returns the converted 10bit result. The adc value per bit depends on the resolution of the ADC. For AVR/PIC(10-bit adc) the adc value per lsb will be 5/1023=0048v
Usage	uint16_t adc_result; adc_result = ADC_GetAdcValue(0); //Adc value for channel 0
