Using Position Manager BiSS-C Library On IDDK
Hardware1

Introduction to IDDKThe DesignDRIVE Kit (IDDK) is a single platform that makes it easy to develop and evaluate design
solutions for many industrial drive and servo topologies. The IDDK offers support for a wide variety of
motor types, sensing technologies, encoder standards, and communications networks, as well as easy
expansion to develop with real-time Ethernet communications and functional safety topologies to enable
more comprehensive, integrated system solutions. Based on the real-time control architecture of TI’s
C2000™ microcontrollers (MCUs), the kit is ideal for the development of industrial inverter and servo
drives used in robotics, computer numerical control machinery (CNC), elevators, materials conveyance,and other industrial manufacturing applications.
The IDDK offers an integrated drive design with a full-power stage to drive a three-phase motor, easing
evaluation of a diverse range of feedback sensing and control topologies. The kit includes a 180-pin
HSEC controlCARD based on the TMS320F28379D C2000 Delfino™ MCU, which integrates dual C28x
real-time processing cores and dual CLA real-time coprocessors, providing 800 MIPS of floating-point
performance with integrated trigonometric and FFT acceleration.
The sophisticated sensing peripherals on the TMS320F28379D MCU, including sigma-delta filter modules
with up to eight input channels, four high-performance 16-bit ADCs, and eight windowed comparators,
enable the IDDK to support shunt, flux gate/ HALL, and sigma-delta current sensing simultaneously. For
position feedback, the IDDK leverages integrated MCU support for resolver and incremental encoderinterfaces. In addition, customers can also explore configuration options that allow the MCU to be placedon either side of the high voltage isolation barrier.
The kit is designed to plug into 110-V/220-V AC mains, delivers up to 8 Amps, and is rated to drive motors
up to one horsepower.
This document covers the kit contents and hardware details, and explains the functions and locations ofvarious connectors present on the board. This document supersedes all documents available for the kit.
For more details, see the DesignDRIVE Development Kit IDDK Hardware Reference Guide (SPRUI23).

3.4

Power Supply
An external power supply is preferred to power the controller during code development so that the board
operates in low voltage. This ensures a safe environment, as there is no high-voltage node present on theboard.
The kit only needs 15 V of power, which can be received through M9 or M3. When the controller
processor is to be on the cold-side, M9 should be used, which is what will be assumed below.
M9 has a power supply jack ([M9]-JP1) and a toggle switch ([M9]-SW1). An external (15-V) power supply
can be fed in through [M9]-JP1, while [M9]-SW1 should be turned away from the Int position when power
is needed.
Settings needed to run when the controller processor is on the cold-side:
1. [Main]-J6, J7, and J8 should be jumpered
2. [Main]-J2 should NOT be jumpered
3. [Main]-R9, R11, R13 should be populated
4. [Main]-R8, R10, R12 should NOT be populated
5. Ground resistors on the secondary side of the board should be configured for the controller to be on
the cold-side. For more details, see the DesignDRIVE Development Kit IDDK - Hardware Reference
Guide (SPRUI23) and the DesignDRIVE Development Kit IDDK - User’s Guide (SPRUI24).
Other options, such as running the PM_bissc project from a controller located on the hot-side, are possible
with different settings. For more details, see the DesignDRIVE Development Kit IDDK - Hardware
Reference Guide (SPRUI23) and the DesignDRIVE Development Kit IDDK - User’s Guide (SPRUI24).

Run the Code
1. Run the code by pressing the Run Buttonin the Debug tab.
2. The project should now run and the values in the watch window should continuously update.
3. Once complete, reset the processor(Run → Reset → CPU Reset), then terminate the debug
session by clicking(Run → Terminate). This halts the program and disconnects Code Composerfrom the MCU.
4. As the encoder sends the position information, observe the same in the watch window as thebiss_data_struct.position variable. The variable biss_data_struct.position reflects the latest position
received by the encoder.
5. If the encoder is not mounted on a spinning motor, the user can manually rotate the encoder shaft andobserve the position changing in the watch window.
6. It is not necessary to terminate the debug session each time the user changes or runs the code.
Instead, use the following procedure. After rebuilding the project, (Run → Reset → CPU Reset),(Run → Restart ) , and enable real-time options. Once complete, disable real-time options and reset
the CPU. Terminate the project if the target device or the configuration is changed (RAM to Flash orFlash to RAM) and prior to shutting down CCS.
7. Customize the project to meet your encoder and application requirements. Change the encoder type inbissc.h. Users can also change the BiSS-C Clock frequency as instructed in the C2000 Position
Manager BISS-C Library User's Guide (SPRUI37).
8. Modify the example code as needed, and perform tests with different cable lengths.
