TMS320x281x, 280x Enhanced Controller Area Network (eCAN) Reference Guide (literature number SPRU074) describes the eCAN that uses established protocol to communicate serially with other controllers in electrically noisy environments. With 32 fully configurable mailboxes and time-stamping feature, the eCAN module provides a versatile and robust serial communication interface. The eCAN module implemented in the C28x DSP is compatible with the CAN 2.0B standard (active).

TMS320x281x, 280x Peripheral Reference Guide (literature number SPRU566) describes the peripheral reference guides of the 28x digital signal processors (DSPs).

TMS320x281x, 280x Serial Communication Interface (SCI) Reference Guide (literature number SPRU051) describes the SCI that is a two-wire asynchronous serial port, commonly known as a UART. The SCI modules support digital communications between the CPU and other asynchronous peripherals that use the standard non-return-to-zero (NRZ) format.

TMS320x281x, 280x Serial Peripheral Interface (SPI) Reference Guide (literature number SPRU059) describes the SPI – a high-speed synchronous serial input/output (I/O) port that allows a serial bit stream of programmed length (one to sixteen bits) to be shifted into and out of the device at a programmed bit-transfer rate. The SPI is used for communications between the DSP controller and external peripherals or another controller.

3.3V DSP for Digital Motor Control Application Report (literature number SPRA550). New generations of motor control digital signal processors (DSPs) lower their supply voltages from 5 V to 3.3 V to offer higher performance at lower cost. Replacing traditional 5-V digital control circuitry by 3.3-V designs introduce no additional system cost and no significant complication in interfacing with TTL and CMOS compatible components, as well as with mixed voltage ICs such as power transistor gate drivers. Just like 5-V based designs, good engineering practice should be exercised to minimize noise and EMI effects by proper component layout and PCB design when 3.3-V DSP, ADC, and digital circuitry are used in a mixed signal environment, with high and low voltage analog and switching signals, such as a motor control system. In addition, software techniques such as Random PWM method can be used by special features of the Texas Instruments (TI) TMS320x24xx DSP controllers to significantly reduce noise effects caused by EMI radiation.

This application report reviews designs of 3.3-V DSP versus 5-V DSP for low HP motor control applications. The application report first describes a scenario of a 3.3-V-only motor controller indicating that for most applications, no significant issue of interfacing between 3.3 V and 5 V exists. Cost-effective 3.3-V – 5-V interfacing techniques are then discussed for the situations where such interfacing is needed. On-chip 3.3-V ADC versus 5-V ADC is also discussed. Sensitivity and noise effects in 3.3-V and 5-V ADC conversions are addressed. Guidelines for component layout and printed circuit board (PCB) design that can reduce system'snoise and EMI effects are summarized in the last section.

The TMS320C28x Instruction Set Simulator Technical Overview (literature number SPRU608) describes the simulator, available within the Code Composer Studio for TMS320C2000 IDE, that simulates the instruction set of the C28x core.

TMS320C28x DSP/BIOS Application Programming Interface (API) Reference Guide (literature number SPRU625) describes development using DSP/BIOS.

TMS320C28x Assembly Language Tools User's Guide (literature number SPRU513) describes the assembly language tools (assembler and other tools used to develop assembly language code), assembler directives, macros, common object file format, and symbolic debugging directives for the TMS320C28x™ device.

TMS320C28x Optimizing C Compiler User's Guide (literature number SPRU514) describes the TMS320C28x™ C/C++ compiler. This compiler accepts ANSI standard C/C++ source code and produces TMS320™ DSP assembly language source code for the TMS320C28x device.

A series of DSP textbooks is published by Prentice-Hall and John Wiley & Sons to support digital signal processing research and education. The TMS320™ DSP newsletter, Details on Signal Processing, is published quarterly and distributed to update TMS320™ DSP customers on product information.
