The problem was “between keyboard and chair” 😉

I forgot to install “Controllino” Libs, not just the board – silly me.

Now I’ve got the following installed:

• Boards: Arduino AVR Boards (1.8.3), Controllino (3.1.0)
• Libs: Controllino (3.0.5)

But now I do get the following error:

Compilation error: Error: 2 UNKNOWN: exec: "/bin/avr-g++": file does not exist

The compiler seems to live in the following directory:

C:\Users\USERNAME\AppData\Local\Arduino15\packages\arduino\tools\avr-gcc\7.3.0-atmel3.6.1-arduino7\bin

Which files to patch so I can get it to use this path?

May I feed 5.000V via X1 into the MAXI Automation to overwrite the internal power supply?

[Friedl_AP]

For what it’s worth, as software the Blinking_LEDs was loaded during the tests.

When only the USB cable is connected, the +5V (X1) vs. GND (X1) measures about 4.17V.

When I switch on the 24V Supply, the +5V (X1) vs. GND (X1) measures about 4.86V.

Multimeter used: Keysight 34461A (calibration date: 23.03.2020)

Dear Jarda!

I’ve now tried the following:

1. Switched ADC to external reference as first command of setup()
2. After loading the code I switched on a lab supply (4.500 V) connected to GND/VREF on X2
3. AI12 is driven by another lab supply with 4.500 V (GND=screw terminal of Controllino, measured versus GND of Controllino)
4. ADC value: 602 (expected (1024/2-1)=511)
5. reduce VREF till ADC value gives 1023
6. VREF measured: 2.653 V (expected 4.500V/2 = 2.25V)

The internal reference is off and connecting an external reference does not really work either.

Code:

#include <Controllino.h>

Servus! Grüße in die Heimat!

It is not possible to change the visibility of the “Profile Text”.

Okay, then why did you remove the label on the MAXI Automation without removing the LED?

The two green LEDs is not in the manual, can you please update the manual? The front face of the MAXI Automation is missing from the manual as well.

Greetings from Graz!
