Hi Jan Cumps,

I don't use the C language often, ut I tried to make a small program, which can read and write legs with parameters.

Usually it works well, but sometimes i get this error:

Segmentation fault

or the other error:

ERROR: Set Chip Settings (42, 0, 0)INFO: Initialization finished...
ERROR: SPI transfer finished unexpectedly (60 fb)

What make I wrong? Ot what can be the reason?

It comes just sometimes... and after 10-15 sec works well again.

Thanks for the help!

Hi!

Very good tutorial!

I don't unterstand something. If there isn't power supply, I get back, that the inpt legs are in HIGH.

Is there some way to check the state of power supply?

I would like to check, is the GPIO cable connected or not.

Really good tutorial!

Fun fact: the GPIO pins are industrial range. In my case 24 V

Do you get to set the threshold level, or is it a kind of pseudo-CMOS thing with the switching level halfway to the supply voltage you're using?
