EVALUATION TOOLS

Breakout Board, ADIS16IMU5/PCBZ

The ADIS16IMU5/PCBZ breakout board provides a ribbon cable

interface for a simple connection to an embedded processor devel-

opment system. Figure 76 shows the electrical schematic, and

Figure 78 shows a top view for this breakout board. J2 mates

directly to the electrical connector on the ADIS16575/ADIS16576/

ADIS16577, and J1 easily mates to a 1 mm ribbon cable system.

EVAL-ADIS-FX3 PC-Based Evaluation

The ADIS16IMU5/PCBZ provides a simple way to connect the

ADIS16575/ADIS16576/ADIS16577 to the EVAL-ADIS-FX3 evalua-

tion system, which provides a PC-based method for evaluating

essential function and performance. For more information, visit the

EVAL-ADIS-FX3 Wiki Guide.

SPI OPERATION

Validating SPI Communications

The ADIS16575/ADIS16576/ADIS16577 provide multiple mecha-

nisms to validate and verify SPI transactions, ensuring reliable

communication.

SPI Error Bit

The DIAG_STAT register includes an SPI communication error bit

(Bit 3). This bit is set to 1 when an SPI communication error is

detected, such as an incorrect number of clock cycles (see Table

15). Regularly checking this bit can help identify communication

issues.

Burst Read Checksum

When performing a burst read operation, a 16-bit checksum is

included at the end of the data stream. This checksum allows the

host system to verify the integrity of the received data. To validate

this checksum, take the following steps:

►

Calculate the checksum of the received data (excluding

FIFO_CNT).

►

Compare this checksum with the checksum value received in

burst read mode.

►

If these checksums match, the data transfer was likely success-

ful.
