Hi
I want to increase the ADC sampling rate. I have tried the below mentioned ADC Prescaler code in wiring.c file. but it was not shown any improvement in ADC sampling rate.
Please suggest.

Actual
"#elif (F_CPU >= 16000000L) // 16 MHz / 128 = 125 kHz
ADC0.CTRLC |= ADC_PRESC_DIV128_gc; "

Modified to
"#elif (F_CPU >= 16000000L) // 16 MHz / 16= 1MHz
ADC0.CTRLC |= ADC_PRESC_DIV16_gc; "
