zero crossing sketch about openmicroinverter HOT 2 CLOSED

About the pulse: are BHI and AHI of U1 both connected to +5V? If pins 9 and 10 of the Arduino produce pulse, the full bridge should switch.

The ZCD sketch is only a demonstrator for a zcd comparator. There is no PWM output produced in this sketch, no syncing of the outputwave either. I use the sign of the input wave in the zcd to prevent from glitches.
I already proved a synced output wave myself, but I need to make the sketch ready for publication. I hope I'll find some time soon. In the end I do not use my zcd for syncing. I use phase sensitive detection on the adc input.

My sketches are meant as thoughts to create all the building blocks that are needed to build a functional inverter with Arduino.

Thank you for your interest.

Yes this project is very interesting, i found a grid tie in the net 3 years ago by tim nolan but it is not worth to try since components availability is through online and expensive that's why i am very excited when i see this repository. Components are available., and also i can make changes about the sensor since the library is open source also. It makes my job easier now.
