National Instruments’ new USB-8451 interface, together with LabView software, eases creation of programs to test, validate and program devices such as such as analog-to-digital converters (ADCs) and EEPROMs.

National Instruments has released a new USB device for use with inter-integrated circuit (I2C) and serial peripheral interface (SPI) communication-devices. The new, NI USB-8451 interface together with its LabView software can be used to create programs to test, validate and program devices such as such as analog-to-digital converters (ADCs) and EEPROMs. Because the module operates on the USB bus, it offers plug-and-play setup, facilitating use in close proximity to the system components.
USB-8451’s interface includes driver software for developing applications without requiring in-depth knowledge of I2C and SPI communications. Besides providing I2C and SPI communication, the new USB-8451 also includes eight digital lines for general-purpose I/O connections and is capable of full-speed USB use. USB-8451 interface can communicate with devices including LCDs, ADCs, and sensors.
