Description
The ZMID520x Evaluation Kit enables evaluation of the IDT
ZMID520x Family of Inductive Position Sensor ICs via IDT's
ZMID520x Application Modules (available separately). It can be
used for the sensor calibration for the following ICs:
 ZMID5201: analog interface
 ZMID5202: PWM interface
 ZMID5203: SENT interface
The main purpose of the ZMID520x Evaluation Kit is communica-
tion between the user's computer and the ZMID520x. The user's
computer sends commands and data via its USB port to the ZMID
Communication Board (ZMID-COMBOARD).
The microcontroller on the ZMID-COMBOARD interprets these
commands and relays them to the ZMID520x located on the
ZMID520x Application Module using the one-wire interface (OWI)
communication interface.
The microcontroller also forwards data bytes from the ZMID520x
back to the computer via the USB connection. These bytes can be
sensor readings, ZMID520x internal registers values, or ZMID520x
EEPROM contents.
The ZMID520x EVKIT Application Software is a graphical user
interface (GUI) that is provided online for the kit. It supports all
ZMID520x configurations and enables the user to understand the
functionality of the ZMID520x as well as perform measurements.
