Microcontroller › AVR › how to speed up ADC of atmega16l
hi,
i am using ADC of atmega16l. i am communicationg the converted digital data via serial cable, but its bit slow. can any one suggest things and techniques to speed up the ADC???
instead of precaler use timers in auto triggering mode… sorry i don’t know exactaly how to do that….
Prescaler is best way to speed up your ADC. Apart from that auto-triggering can be used. The advantage of auto-triggering is that there is no need to set ADSC bit again and again. Autotirigger mode activate the convsersion automatically. To learn this you can follow the link
there is always a maximum working frequency of the inbuilt adc..It is generally mentioned in the datasheets..!
usig prescalars you can get the frequncy high but inside the maximum frequency..
However, if you increase the frequency , the accuracy of the conversion decreases..so if you really want a fast adc, get an external one
Hi Bilal,
Please post your code also.
