Returns

A dictionary mapping serial port names to serial numbers

See also find.

picodaq.device.find(serno: str) → str

Find a picoDAQ by serial number

Parameters

Dictionary with information

If no port is specified, the first device found on the system is queried. If no device is found, an exception is raised.

The result is a dictionary defining the following keys:

firmware: the firmware version of the device hardware: the hardware version of the device serialno: the serial number of the device analog_in_count: the number of analog input channels analog_out_count: the number of analog output channels digital_in_count: the number of digital input lines digital_out_count: the number of digital output lines max_sampling_rate_Hz: the maximum sampling rate, in hertz analog_in_range_V: the input voltage range analog_out_range_V: the input voltage range

Voltage ranges are returned as a tuple expressing the minimum and maximum values in volts.
