ADIS16135 SPI Interface Configuration

Question

How do I configure the ADUC7026 to communicate with the SPI on the ADIS16135?

NevadaMark · Accepted Answer

Embedded processors typically support SPI communications with multi-purpose SPI ports that have some configurable parameters. These parameters could include serial protocol (SPI, I2C, etc), data length, clock polarity, clock phase, bit order, serial clock rate, etc. While it is important to check the sensor's datasheet for product-specifc settings, Table 7 in the ADIS16135 Datasheet (page 8) offers a summary of typical configuration parametes to look for, which are typically found in serial port control registers. Table 7's contents are provide here, for convenience.
