Just tested and works fine First burn the LarduinoISP.ino to your working Nano Then hook it up like ``` // pin name: Programmer NANO Target LGT8FX8P: // reset: 10: PC6/RESET...

I also used LGT Nano

This is how I wired it up

I can confirm your issue. I tried an Atmega8 on both 8MHz and 16MHz and in both cases the examples compiled fine, but did not work. With the Attiny85 and...

Cool thanks Vahadg I will hook up some stuff this weekend and give your suggestions a try. Declaring TCCR1B twice is not a typo? You did not mean one of...

Are you maybe using a HC-SRO4 library that does not support the modern Attinies and subsequently gets all of its timekeeping wrong?

I am getting the same as you. tested with a AT404 The odd thing is that pulsein gives different feedback when you compile for different clock speeds. E.g. when I...

I have created a small demonstrator program that requires no external parts The RTC is used to toggle a pin, because the RTC has it's own clock. Then micros() and...

I have tested again with an older version of MegaTinycore (2.6.8) and in that version Pulsein works fine. 2.6.9 is not installable, (CRC error), so this regression took place in...
