Note:
1. Sampling Rate: This parameter refers to the acquisition speed of the ADC chip.
2. Number of Enabled Channels: Configured by the host computer software, check the box under "Sampling Enable", and the customer can independently select the number of channels and channel numbers to enable sampling.
3. Data Communication Rate: This parameter refers to the communication speed between the MCU controller and the host computer.
