Prototype

sub procedure ADC_Set_Active(dim adc_gs as ^TADC_Get_Sample)

Description Sets active ADC module.
Parameters Parameters:

adc_gs

: ADCx_Get_Sample handler.

Returns

Nothing.

Requires

Routine is available only for MCUs with multiple ADC modules.

Used ADC module must be initialized before using this routine. See ADCx_Init and ADCx_Init_

Advanced routines.

Example

‘ Activate ADC2 module

ADC_Set_Active(@ADC2_Get_Sample)

Notes

None.

Library Example

This code snippet reads analog value from the channel 1 and sends readings as a text over UART1.

Copy Code To Clipboard

program ADC_on_LEDs

dim ADCresult as word

txt as char[6]

main:

PORTB = 0x0000 ‘ clear PORTB

TRISB = 0xFFFF ‘ PORTB is input

ADC1_Init() ‘ Enable ADC module

UART1_Init(9600) ‘ Initialize UART communication

while TRUE

ADCresult = ADC1_Get_Sample(1) ‘ Acquire ADC sample

WordToStr(ADCresult, txt) ‘ convert its value to string

UART1_Write_Text(txt) ‘ and send it to UART terminal

Delay_ms(50)

wend

end.
