ADC
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
| Definition | void ADC_Init() |
| Input Arguments | none |
| Return Value | none |
| Description | This function initializes the ADC module. |
| Usage | void main()
{ ADC_Init(); } |
ADC_GetAdcValue
| Definition | uint16_t ADC_GetAdcValue(uint8_t var_adcChannel_u8) |
| 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 |
