Hi
In one of our application I have to read the internal register values of the sensors. I am using NI 8451 card.
Pin Details of the sensors are-
My question is NI 8451 is having separate pins for SDO & SDI But sensor is having one pin for SDIO. How to connect them ,I have to read the register values & some registers are read/writable.??
Please reply as soon as possible, it is very urgent

Maybe the SDIO name has confused the issue. On the 5020 SDIO just means Serial Data Input/Output. The communication protocol used on the 5020 is I2C. So you should be using pin 29 and 30 on the 8451 as the proper connections for I2C to read/write the 5020 registers.

R,
I am wrong. The 5020 is indeed SPI. I am sorry.

Hi
Thanks for reply.
I am using SPI communication not I2C.And i have to interface 6 sensors (slave devices) with the NI USB 8451 device.
