Using the AARDVARK

The Aardvark I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter through USB
(see

). It allows a developer to interface a Linux or Windows PC to a downstream embedded

system environment and transfer serial messages using the I2C and SPI protocols.

Part Number: TP240141

RoHS Compliant: Yes

Figure 5. Aardvark I2C/SPI Host Adapter

For more information, visit the manufacturer website at:

http://www.totalphase.com/products/aardvark_i2cspi/

Level translation is required due to the different signaling levels (3.3 V for the Aardvark vs. 1.9 V for the
ADC). A level shifter can be obtained from Total Phase or can be built as shown

Figure 6. Level Translator for Aardvark to ADC

1. Download the Aardvark control GUI software

(a) Go to:

http://www.totalphase.com/products/aardvark_i2cspi/

and select the Downloads tab.

(b) Download and install the Control Center Software.

2. Configure and connect the hardware

(a) Put the ADC into Extended Control Mode (ECM) by setting the ECEB jumper to GND.
