Re: How to totally reset a C. Mega?

Hi, I must admit, I totally forgot this topic - I have sent the Controllino back and received another one, which is working correctly. But you're right - the double usage of the same COM port is a bit strange; from another PC with meanwhile dozens of USB-serial-devices I'm used to growing COM port n...

Re: Convert from Mega to Controllino Mega - KeyPad problem

next steps are done: 1st - changed the connectors from the above mentioned "Ax" into Dx" (X1/12..17, X2/12..13) and everything works well. 2nd - so far so good - but why use so many ports? try i2c also for keypad, as we already do have a 20*4 LCD on the bus.

Re: Convert from Mega to controllino Mega

add-on: maybe this can help for analysis

since it's getting a bit darker out here and I had not yet the lights switched on, I just saw by fortune that the A8..A11 LEDs come alight _very_ dimly, when I press keys on the KeyPad.
