Hi, I might have found a bug in the siemens gpio nodes from the iot2050 in node-red, more clearly the input node. If I use the CLI command “mraa-gpio get 1 (before deploying), the iot2050 reacts normally and I get the expected response (when not pushing the push button). But if I deploy the node, the digital input gets immediately pulled up. When I use the CLI command “iot2050setup” and configure the pin to the pull-down mode, the problem seems to be solved until I restart the iot2050. See link:demo. In the attachment you can find the schematic and how the push-button and multi-meter are connected to the iot2050. When I test this setup on a raspberry pi with the pi gpio nodes I don’t have any problem and the system works as expected. IOT2050 image: IOT2050_Example_Image_V1.0.2.img Nodes are on the latest updates. Has anyone experienced the same problem so far? Kind regards, AttachmentPictures.zip (372 Downloads) |

Hi, Yes indeed. The moment i deploy the siemens input node, it will pull the input high. Even when i have set it to pull-down in the iot2050setup. Kind regards |

Not a solution yet, but I created an issue to not lose this requirement: https://github.com/siemens/meta-iot2050/issues/135 |
