wayland/mcp9808-thermometer/get-resolution

Get resolution mode of device. MCP9808 has four resolution modes (resolution and sample time in parentheses): 00h ( 0.5°C , 30 ms); 01h (0.25°C, 65 ms); 02h (0.125°C, 130 ms); 03h (0.0625°C, 250 ms).

RESOLUTIONbyte
Resolution mode. Should be one of the following four values: Mode Resolution Sample time 00h 0.5°C 30 ms 01h 0.25°C 65 ms 02h 0.125°C 130 ms 03h 0.0625°C 250 ms
To use the node in your project you should have the wayland/mcp9808-thermometer library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
