This application report presents a method for utilizing the on-chip pulse width modulated (PWM) signal generators on the TMS320F280x™ family of digital signal controllers as a digital-to-analog converter (DAC). The method involves analog low-pass filtering the PWM signal to remove high frequency components leaving only the low-frequency content. Theoretical and experimental results are presented
TI’s Impedance Track (IT)™ fuel gauge is designed for accurately reporting battery remaining capacity and run time. It is `necessary to configure and use the gauge correctly to achieve this. The bq27410 differs from the traditional IT-based gauges which require battery chemistry information and a learning cycle to achieve high accuracy. The bq27410 does not require battery chemistry selection o
On the Texas Instruments (TI) (tm) TMS320C54x the I/O port addresses are hard-coded in the opcodes for the PORTW (I/O port write) and PORTR (I/O port read) instructions. This document discusses how the tables of data can be transferred using sequential I/O port addresses.The fact that the I/O port addresses in the PORTR and PORTW instruction are hard-coded makes reading or writing a table of
This application report demonstrates the procedure used to program the TMS320VC5503/C5506/C5507/C5509/C5509A inter-integrated circuit (I2C) peripheral module. Basic operations of the I2C including reading and writing and the initialization of the I2C bus are covered. These operations are illustrated using the I2C routines provided in the chip support library (CSL). For more information see the
This application note provides information concerning the various revisions of the TI CDC2509/10 family of devices. In addition, it will assist designers with new and existing designs. Phase error inf
This report provides a summary of using the INA19xA-Q1 device when the common mode voltage is close to zero volts. In this low common-mode voltage region, the output voltage has a large error. The exa
The Charge-Coupled Device (CCD) sensor is widely used in many video applications such as scanners digital cameras video camcorders etc. In these video systems a processor or hardware circuit processes the CCD raw data before displaying or implementing other image processing algorithms. The process of producing color data from the CCD raw data is called color reproduction.In this applicatio
The Texas Instruments SN74SSTV16857 and SN74SSTV16859 registers support the low-power mode of the DDR-DIMM. This application report explains the low-power mode and the features of the registers that support the low-power mode. Also the considerations that the system designer must be aware of when implementing the low-power state of a registered memory module are explained. The sequence that must
This document contains an example that shows the code required to set up serial port interrupts on a 'C5x DSP. This technique can be applied to any other interrupt. Several code examples are given.
