Thank you![/quote] <p>Which configuration are you currently using for you SAADC and TIMER setup, and what are your requirements to the sampling frequency of the SAADC?<br />You mention that the sampling frequency is not stable and not high enough, could you elaborate on what you mean by this?</p> [quote user=""]The program crashes before executing the first line in main()[/quote] <p>Please share the error message / output log from the instance where this occurs.<br />Is the build and flashing completing successfully, or are there any warnings?<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
