Does the NI-USB-8451 Support 16 Bit Transfers? Hardware: Industrial Communications>>CAN
Problem: I have a National Instruments USB-8451 I2C/SPI device and need to do 16 bit transfers. Is this possible? Solution: The USB-8451 only supports 8 bit transfers. You can still write a 16 bit number, but there will be a small delay between the 2 bytes (approximately 10-20 us). This is a small delay and is typically not a limiting factor in your program. The approach you would take when writing or reading a 16 bit number is to write or read a byte array of length 2. You can use a Type Cast to convert back and forth between arrays of 8 bit integers and arrays of 16 bit integers. Related Links: Products and Services: NI USB-8451 Attachments:
