Home Support ¿La Tarjeta NI-USB-8451 Soporta Transferencias de 16 Bits?

¿La Tarjeta NI-USB-8451 Soporta Transferencias de 16 Bits?

Hardware: Industrial Communications>>CAN

Problema:

Tengo un dispositivo USB-8451 12C/SPI de National Instruments y necesito hacer transferencias de 16 bits. ¿Es esto posible?

Solución:

El dispositivo USB-8451 sólo soporta transferencias de 8 bits. Usted puede escribir un número de 16 bits, pero habrá un pequeño retraso entre los 2 bytes (aproximadamente 10-20 us). Este retraso tipicamente no representa una limitante en su programa.

La forma de realizar esto es establecer un tamaño del byte de arreglo de 2 cuando vaya a escribir o leer un número de 16 bits. Puede utilizar Type Cast para convertir entre arreglos de 8 bits y 16 bits.
