Midi control for microscopes using pymmcore

pymmcore-midi

MIDI Device control for microscopes using pymmcore

Installation

pip install pymmcore-midi

Usage

Create a pymmcore_midi.DeviceMap object (can be done from a YAML/JSON file), then connect it to a pymmcore-plus CMMCorePlus object.

device_name: X-TOUCH MINI
mappings:
  - [button, 8, Camera, AllowMultiROI]
  - [button, 9, Camera, Binning]
  - [knob, 2, Camera, Gain]
  - [knob, 9, Camera, CCDTemperature]
  # can also use this form
  - message_type: control_change
    control_id: 1
    device_label: Camera
    property_name: Exposure
  - message_type: button
    control_id: 10
    core_method: snap
  - message_type: knob
    control_id: 17
    core_method: setAutoFocusOffset

core = CMMCorePlus()
core.loadSystemConfiguration()

dev_map = DeviceMap.from_file(f)
dev_map.connect_to_core(core)

Now when you move a knob or press a button on your MIDI device, the corresponding property/method will be updated/called on the CMMCorePlus object. :tada:

Debugging/Development

Use the environment variable PYMMCORE_MIDI_DEBUG=1 to print out the MIDI messages that are being received from your device. (This is useful to determine the appropriate message type and control ID for your device map.)
