/SPI Interface Device -
-The NI USB‑8451 is a host interface for interfacing with integrated circuits (I
²
C), system management bus (SMBus), and serial peripherals Set up and communicate with an inte
rface (SPI) device.
-Featuring a plug-and-play USB connection, the USB‑8451 is a convenient way to communicate with consumer electronics or integrated circuits portable solution.
-It also includes eight general-purpose digital I/O lines that can be used for a variety of applications, such as configuring the address of an I2C device or toggling an LED.
-The USB‑8451 can be mounted closer to the I
²
C/SPI device than the PCI interface, reducing the I
²
C bus length and making the maximum Minimize noise problems.
-In addition, the interface does not require an external power supply to provide +5 V and GND voltages to the power circuit.
-You can download NI Labview and NI DAQmx software for free. They are enough for USB-8451.
