Hi all,
im trying to build a multi channel servo controller ill be using a PI 3B + with the i2c servo board ( 16 channels per board), what i would like to do is:
Set a time period
Realtime record servo positions ( analog controllers!) record to influxdb
edit a graph to adjust the position of individual servos
save then playback
its the graph thing im struggling on how to deal with. is the a node that might exist?
I used to do this with midi years ago and used some audio software to adjust the midi values.
Basically an animatronics copycat system.
I did years ago with the chart node to setup my room thermostats. The flow is old and filled with a ton of legacy code from my early Node-RED years. Certainly not a task Node-Red is good for. If I would do it again I still would use the dashboard but with one custom ui node.
Must be honest that I see potential in the proposal from @vikingsraven, because there are a lot of use cases.
Would be nice if somebody could implement a UI widget for this. I'm too busy with other nodes at the moment. The link from @TotallyInformation is a great starting point, but of course extra features would be nice: e.g. have a selection rectangle to (re)move multiple datapoints simultaneously, and so on...
Every time you are stuck, don't hesitate to ask your question here. We will assist you. Always nice to see folks that are interested to start building something like this...
Good luck!
