i bought an controllino Maxi and tried to generate a flipflop signal, working in 24V mode.
1) I hadn’t expected such a long jitter period, around ~9ms. My target was to change the flipflop signal every 2ms. Is there another possibility to achieve this without using the raw ATmega signal at 5V? Thats what i wanted to avoid by using the controllino.
2) Secondly, the voltage at the low level is still around 11V – shouldn’t that be much lower? The datasheet says it should be 0-4,8V. (Checking the pinout on top, the ATmega is generating a proper 5V/0V flipflop)
please note that the screw terminal digital outputs of CONTROLLINO MAXI are High Side switches. They are only connecting/disconnecting the terminal to/from supply voltage. Not ground. I think that this is the reason for your troubles.
