Re: Is it possible to reset Controllino when external power source is connected?

Hi, my spontaneous idea: wire a branch of the +24V to a digital input port (maybe even an analog one). This input port then changes to High, when the 24V becomes active, and goes Low again, when 24V is off, but power remains by USB. Then define an event "Input switches Low->High" to run your init ro...

Re: 4-20mA analog input

ooppss ... never cared about, never took values; it is working "as is", just a resistor between signal and ground.

Re: 4-20mA analog input

Hi, we've had a similar job a few weeks ago: a laser for distance measurement, operating on 24V, gives 4-20 mA, that the Controllino shall read as analogInput. The manufacturer offers an adaptor cabling with a 250 Ohm shunt between the laser's signal output and ground, to produce 0-5 V analog curren...

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...

How to totally reset a C. Mega?

Hi, we bought 3 Controllino Mega about mid November. Now, as the project is working in the test environment and the machine #1 gets shipped, the preparations for #2 are on. You can imagine my astonishement, when the 3rd Controllino not only gets a different COM-port on the same PC (the other 2 get C...

Re: Powering the Controllino Maxi

Hi,

yes, you can - better: you must, if you want to use Inputs or Outputs on 12V - otherweise you only have the top side 5V pins available for use, and not even all of these with full useability, for instance the I2C may not give enough power for multiple devices ...

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. Buy pcf8574, connect and check with small...

Re: Convert from Mega to Controllino Mega - KeyPad problem

another add-on:

the same behaviour ist on execution of the KeyPad sample sketch ... so I dare to say it is not the software causing the problem ...

Re: Convert from Mega to controllino Mega

next add-on:

some debug printlns later, I see that there is a rogue "key 1 pressed" on start of loop (), but only once.
That guides me into "are the ports/pins the correct ones?"

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.
