This application note describes a method for developing block-oriented I/O device drivers
for applications that use the DSP/BIOS real-time kernel and includes examples that run
with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and
TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has
now been superceded with an updated version that supports not only block oriented
devices, but also devices such as UARTs, PCI and USB buses and Multimedia cards.
Documentation on the updated driver model as well as example drivers and source code
can be found in the Device Driver Developer s Kit product now available for download
from the TI Developer s Village.
The MATLAB coding style, project options and synthesis directives can have a significant effect on the final results. Knowledge about how a particular algorithm should be implemented in hardware can be reflected in the MATLAB code to improve the results. In doing so, the MATLAB loses a bit of its abstraction but the lower-level MATLAB will infer the desired architecture into the device.
TION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
WARNING!
Although the AD7008 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
This C++ code example provides a method for transferring objects or chunks of
data from one device to another via the Bluetooth OBEX protocol. These chunks
are typically files or other blocks of binary data. This example demonstrates
how to run OBEX on top of the Bluetooth RFCOMM protocol, but OBEX can also be
used with other transport media, such as IrDA and USB.
The development of a data acquisition card based on USB bus is introduced in this article.It first describes the configuration and principle of this card in the part of hardware design,and then the application program and device driver in the part of software design.Data acquisition program in firmware is also discussed.Finally,this data acquisition card is tested and evaluated in a program developed by Lab Windows CVI,which shows that this car is stable and reliable
The TMS320C64x™ DSPs (including the TMS320DM642 device) are the highest-performance fixed-point
DSP generation in the TMS320C6000™ DSP platform. The TMS320DM642 (DM642) device is based on
the second-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW)
architecture (VelociTI.2™ ) developed by Texas Instruments (TI), making these DSPs an excellent choice
for digital media applications. The C64x™ is a code-compatible member of the C6000™ DSP platform.
This the second tutorial of the Writing Device Drivers series. There seems to be a lot of interest in the topic, so this article will pick up where the first left off. The main focus of these articles will be to build up little by little the knowledge needed to write device drivers. In this article, we will be building on the same example source code used in part one. In this article, we will expand on that code to include Read functionality, Handle Input/Ouput Controls also known as IOCTLs, and learn a bit more about IRPs.
build a modbus client/server for use on the Protocessor (from FieldServer Technologies)
Tools Required:
1. Microchip MCC18 compiler.
2. ICD2 debugger (or other device to program your PIC)
3. Protocessor hardware.
DirectFB is a thin library that provides hardware graphics acceleration, input device handling and abstraction, integrated windowing system with support for translucent windows and multiple display layers on top of the Linux Framebuffer Device.
usb bulk 傳輸例程。
* The bulkusb driver is a generic function driver, based on the Windows Driver Model (WDM).
* Supports Plug and Play(PnP), Power Management(PM), Windows Management Instrumentation (WMI) and the Selective Suspend (SS) features.
* This sample is based off the selSusp DDK sample. Please refer the selSusp sample and the DDK docs to understand the handling of PnP, PM, WMI and SS features and implementations.
*
The USB device used for this sample is a generic Intel I82930 USB evaluation board programmed with a simple loopback test using a 64 KB circular buffer. None of the code in the sample is specific to this controller chip.
