Peter, there should be plenty in Media.fth to get me writing inline words. I'll make notes as I go.
Hi, has anyone managed to load a piece of assembler as a block into cog ram?
I have the following short loop ( a DDS sine generator) and would like to load it as a module into the cog.
long ampl 32767 ampl ! long dangle 5.000.000 dangle ! code sineAsm ( d:ampladr c:dangleadr b:offset a:angle -- ampladr dangleadr offset angle ) BEGIN: rdlong xx,d '\ get amplitude qrotate xx,a '\ calculate sine rdlong xx,c '\ get delta angle add a,xx '\ new angle getqy xx '\ get sine result add xx,b '\ add offset wypin xx,#0 '\ output to pin 0 AGAIN: end : sineAsmTask 0 PIN 1650 mV ampl dangle 32767 0 sineAsm ; ' sineAsmTask 6 RUN
Thanks for some hints!
