Good evening everyone and hello podia!

I tried the new sketch, it's perfect!
the wave is tracked perfectly,
in a short time I will do the test of the two superimposed voltages with connected light load.

I have inserted these lines in the sketch which probably improve
the overall system noise.
with my instruments I do not appreciate the differences,
maybe with your rigol1054 you notice something.


#include <avr/power.h>

setup()
{
 //https://www.gammon.com.au/forum/?id=11497
 //power_adc_disable(); // ADC converter
 power_spi_disable(); // SPI
 //power_usart0_disable();// Serial (USART)
 power_timer0_disable();// Timer 0
 //power_timer1_disable();// Timer 1
 power_timer2_disable();// Timer 2
 power_twi_disable(); // TWI (I2C)
 DIDR0 = DIDR0 | B00111111;           //Digital input disabled on all ADC 0-5 ports
}


let me know otherwise if there are no differences I delete them: D

to see if I understand how the new sketch works I will try to experiment on a sketch with different PWM freq and NPWM
in order to verify how the parameters affect.

thank you soon, A.
