So I was trying this code I got right off a book but changing the pin
where I should have the PWM signal output... but it is not working...
any guesses why?... PD: I can't do debugging because I have a strange
error on executing the ELF file.
Wrote this code on and did the programming on atmel studio 7 with the
atmel - ice.
#include "sam.h"
unsigned char* ARRAY_PORT_PINCFG0 = (unsigned char*)®_PORT_PINCFG0;
unsigned char* ARRAY_PORT_PMUX0 = (unsigned char*)®_PORT_PMUX0;
int main(void)
{
REG_GCLK_CLKCTRL = 0x401A; //TCC0 para PWM en GCLK0
REG_PM_APBCMASK |= 0x00000100; //Enable TCC0, es la funcion F para el pin PA17
REG_TCC0_CTRLA = 1; //Reset al registro
while(REG_TCC0_CTRLA & 1){} //Esperar hasta sincronizar
REG_TCC0_WAVE = 2; // Modo PWM normal
REG_TCC0_PER = 16666-1;
REG_TCC0_CC0 = 5555-1;
REG_TCC0_CTRLA |= 2;
ARRAY_PORT_PINCFG0[17] |= 1; //Activa el multiplexor a perifericos
ARRAY_PORT_PMUX0[8] = (0x5<<4);
while (1)
{
}
