In-Depth Information
SCI: The serial communications interface is a two-wire asynchronous serial port,
commonly known as UART. The SCI contains a 16-level receive and transmit
FIFO for reducing interrupt servicing overhead.
I2C: The inter-integrated circuit (I2C) module provides an interface between a
DSC and other devices compliant with Philips Semiconductors Inter-IC bus (I2C-
bus) specification version 2.1 and connected by way of an I2C-bus. External
components attached to this 2-wire serial bus can transmit/receive up to 8-bit data
to/from the DSC through the I2C module. On the 2833x/2823x, the I2C contains
a 16-level receive and transmit FIFO for reducing interrupt servicing overhead.
More details about TMS320F28335 can be found in (TI 2007).
1.3.7.2 TMS320F28335 ControlCARD
Texas Instruments offer a controlCARD 2 that is equipped with a TMS320F28335 to be used
for initial software development and short run builds for system prototypes, test stands, and
many other projects that require easy access to high-performance controllers (TI 2002). The
controlCARDs are complete board-level modules that utilise an industry-standard DIMM form
factor to provide a low-profile single-board controller solution. All of the C2000 controlCARDs
use the same 100-pin connector footprint to provide the analog and digital I/Os on-board
controller and are completely interchangeable. Each controlCARD provides an isolated RS-
232 interface for communications. The host system needs to provide only 5 V power to the
controlCARD.
1.3.7.3 TMS320F28335 Experimenter Kit
Texas Instruments also offer an experimenter kit 3 that is equipped with a TMS320F28335
DSC. It is an ideal product to be used for initial device exploration and testing. The kit has
a docking station with access to all controlCARD signals, breadboard areas, RS-232, JTAG
connector, and on board USB JTAG emulation. Each kit contains a 28335 controlCARD and
is complete with Code Composer Studio TM IDE v3.3 C28x TM Free 32 K Byte Version. C2000
applications software with example codes and full hardware details are also available. Note
that no separate JTAG emulator is required, as the docking station features on-board USB
JTAG emulation.
1.3.8 Test Equipment
In order to test the working condition and performance of inverters, many instruments
are needed. In addition to conventional multi-meters and oscilloscopes, etc, power analy-
sers/meters are often needed.
