* most intialization values are generated using Code Wizard and depend on clock value Wdogtrig() // call often else processor will reset Init_initController() // this must be the first 'init' action/call!ĪDCSRA = 0b10000111 //set ADEN, precale by 128

I don't know how i can make it any easier to run so that it can tolerate more than 4 samples ( #define N 4) #define M_PI 3.1415926fĪDCSRA |= 0b01000000 //start conversion I have made (with the great help of an answer to a recent question) the code almost 18 times smaller than it was originally. I'm forced by the university to design the code through CVAVR, using a DFT. If i set the number of samples any higher than 4, the chip LEDs will just flash continuously and the code won't get past the pin reading phase of the process (tested with lighting up LEDs after each line of code to see where it stops). I'm designing a guitar tuner through CodeVisionAVR and using an ATmega164 microchip for my university project.
