Look Up Table in 28335
Hello, i need to do a look up table to save a non-sinusoidal wave, i dont know how start, is there a manual or post to folow...
Try the following software examples http://focus.ti.com/docs/toolsw/folders/print/sprc083.html on look-up table implementations.
Hello Arefeen, i have been the examples,,,and I understand them.. thanks...
this use a table SINTB360.ASM, so if I replace the values of my wave in this table i can get my LUT...
my question is... if these procedure the correct solution??
Hello ...there are multiple ways to generate a waveform including lookup table method. The examples work fine to generate a sine wave. If you have a nonsinusoidal but a repeatable waveform (basically has a fixed frequency) then this lookup table method should work for you as well ..... simply replace the sine table with your table representing the nonsinusoidal waveform. The quality of your nonsinusoidal waveform will depend largely on the type of nonsinusoidal waveform, the size of table etc.
thanks Arefeen.. I'm goin to try... i would like to know how place the LUT in the Program memory:
the manual said: edit Linker command file: SINTBL >PROG PAGE 0 how do this??in what adress?
