Thanks for the quick answer. Nano is 5v. Looks like I need the level shifter. Have checked the net as I have a cheap 4 chn module. It is not recommended for SPI. People recommend TxB0108. I remember Jorgen has raised the question about the ST7789 driver in FC8 forum. If this Estardyn module has the ...

Hi Question about the module: Estardyn 2.0 Inch TFT LCD Display with Rotary Encoder EC11. ---------------------------------------- Cannot find some documentation about this module on net. AI says that module should use the ST7789_driver. Not sure if I have to use (for Nano) the level shifter (5v to ...

I do not play this metaphorical 'ton of meat' Australian raffles (for local footy club?). I am locked to the holiday home project 2.5 hours drive away from Adelaide now. And I am too old, anyway... About the 'ton" vs "tonne" prononciation. Is it true, that ton pronounces as sun (imper...

OK. Good luck with your visit to Au.
Yes, it is cold at morning in June, but summer is back at midday.

Thanks
Do you plan to visit Adelaide?

Hi chipfryer27
Can you please say a few words about yours multiprogrammer?
What brand is it?
What MC it does?
Thanks

This discussion is important.
I did not use the external 1s clock (pulse) before.
I am working right now on KiCad PCB for my project with the freq timer.
Will update the situation a bit later.
Thanks all for help.

Sure. Will do.

Hi Martin
I like the idea of external 1Hz pulse.
Looks like this is the key to a good freq meter with Arduino.
Will test it with Mega shortly.
Thanks.

I need to measure the freq fr 40kHz to 200kHz.
Thanks for suggesting to use the RTC 1s reference signal.
Will try it.
Thanks again.
