Can you actually make money working at McDonalds? A friend of mine worked for Roy Rogers one summer and they would have him work for a couple of hours and if things slacked up, he had the choice of clocking out and hanging around to clock back in if they picked up or just going home. After taxes he would make enough each day to pay for a burger... after the employee discount! I don't know how much a Spectrum Digital board costs, or even which board we are talking about. But if there aren't any open source DSP boards like this there should be. The Beagle Board is an excellent example of what open source hardware can be. For $150 you get a board with all sorts of software and support. Rick

Please help me out if you know, how to flash a DSP via parallel port or serial port and its connections. swager

Please help me out >if you know, how to flash a DSP via parallel port or serial port and its >connections. 3.2.10 Boot ROM The Boot ROM is factory-programmed with boot-loading software. The Boot ROM program executes after device reset and checks several GPIO pins to determine which boot mode to enter. For example, the user can select to execute code already present in the internal Flash or download new software to internal RAM through one of several serial ports. Other boot modes exist as well. The Boot ROM also contains standard tables, such as SIN/COS waveforms, for use in math-related algorithms. Table 3--4 shows the details of how various boot modes may be invoked. See the TMS320x281x DSP Boot ROM Reference Guide (literature number SPRU095), for more information. SPRU095 looks pretty straightforward. The SPI loader might be the easiest. -- Rich Webb Norfolk, VA |
