| This topic uses the DSP graph processing technology and sensor signal implementation hypothesized level instruction graph the display control to explore feasibility of hypothesized platform application, endeavour to eliminate the response lag and error which because the machinery horizontal lightpost creates, It is a great improve precision on enhances help the ship-based helicopter falls the equipment, and advantageous to the enhancement ship-based helicopter security.Having studied the matching colors of digital figure, color space and digital figure, the principle of matching colors according to VGA on this basis, combine the test and provide some value of matching standard of GSB G51001-94(the edition of 2000) on the PDD in CCS2.2, integration development environment provide by TI for its DSP .and use C language work out the left-pointer graphical display program, output the figure on the PDD through the interface of VGA.When design of left-pointer and right-pointer figure display synchronously program in rolling indictor by C language,study something on double thread,and accomplish output rolling indictor figure timesharing through the interface of VGA and CVBS in single thread. Finally , complete servo control glide and rolling indictor figure through ZC-TD-30S digital angle transducer ,which output digital signals by sensor that fix the on turntable. |
