Using the ADC SPI Interface Software

Once the software is installed and the USB cable is connected, three primary modes of operating the
software are available: SPI Register Writes, SPI Register Write Using a Script File, and ADC Frequently
Used Registers.
3.2.1 SPI Register Writes
The most basic mode of operation allows full control of writing to individual register addresses. In the top
left corner of the interface screen, select the ADS5545/46/47/25/27/60/62 from the ADC SPI Protocol
drop-down list. Next, type the Address Bytes(s) in hexadecimal (hex) and Data Byte(s) in hex which can
be found in the device data sheet. When you are ready to send this command to the ADC, press "Enter"
on your keyboard, or press "Send Data". The graph indicator is updated with the patterns sent to the ADC.
The default inputs to both the Address Byte(s) and Data Byte(s) fields are hex inputs as designated by the
small "x" in the control. Users can change the default input style by clicking on the "x" to binary, decimal,
octal, or hex. Multiple register writes can be written simply by changing the contents of the Address
Byte(s) and Data Byte(s) field, and pressing Enter again.
