Only one PWM output can be used at the same time. The second one must be switched off: OCR1B or OCR1A set to zerro.

SOURCE CODE ATMega1284P:


/*************************************************************************************

/************************************************************************************* #include #include #include //#define F_CPU 8000000UL #include #include #include uint16_t i; void PWM_Init(); void PWM_Init() PWM_Init(); while(1) //infinite loop _delay_ms(2000); //maximum speed for (i=0;i<1000;i++) //soft stop OCR1A = 0; _delay_ms(2000); } } ***************************************/ 

 

 Second version- the best one
