Re: RevPi Module Verbindung

Hallo renehoesele, danke für die Informationen, die du bereitgestellt hast; das war hilfreich. Offenbar scheint die RS485-Kommunikation auf der PiBridge mit den I/O-Modulen nicht zu funktionieren. Dann kann unglücklicherweise auch kein Firmware-Update funktionieren. Ich werde einen Testaufbau erstel...

Re: DO module: Detecting open load

Hello cerberus78, to round off the topic, please note the following: OpenLoadDetection is only active when the monitored output is low. If voltage is present, monitoring is deactivated. In addition, it is not possible to differentiate precisely between overtemperature, overload and openLoad See here...

Re: Benachrichtigung bei GPIO-Pin Änderung

Hi Rumpelstilzchen, wenn du ein RevPi DIO Modul benutzt, dann sind dort ja die betreffenden MAX31913 verbaut. Das kann man in den Schaltplänen sehen, die sich hier befinden: https://revolutionpi.com/en/tutorials/downloads#schaltplaene Aber ich wüsste jetzt nicht, wie du diese per GPIOs ansteuern kan...

Re: RevPi Core S - Problems reading USB port Serial data

Hey Victor, I have created a test setup and hope it shows how easy you can transfer serial data: 1. Start miniterm python3 -m serial.tools.miniterm /dev/ttyUSB0 2. Set local echo on [STRG] + T, [STRG] + E 3. Monitor Pin 2 of D-SUB-9 plug - Pin 5 is GND USB RS232 Sniff RX Pin.JPEG 4. Type something i...

Re: RevPi Core S and moDIO closing SSH randomly

Okay but the PWR LED thing here made me think, I hadn't considered this detail yesterday. Hm. So if the PWR LED turns red and then green again, this is a sign that the communication between the modules is faulty. The I/O modules then go into the safe state and switch the outputs to logic 0. Can you ...

Re: DO module: Detecting open load

No, unfortunately. You need to have a load to detect an open load and thus some electricity flowing through a cable.
