hello all, recently i am working on a project that is variable frequency drive. i am using pic microcontroller for the programming purpose.in the programming section, i have one sine look up table and have to generate various such tables during run time(each table corresponds to a particular frequency).
now i want a logic that can generate various look-up tables for me from one table during run time. for sample purpose, i am posting to tables here, one for 50hz output frequency and other for 10hz output frequency. if anyone can help, kindly reply.
fiftyyy=[0, 2, 3, 5, 7, 8, 10, 11, 13, 15, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 31, 32, 33, 33, 33, 34, 34, 34, 34, 34, 34, 34, 33, 33, 33, 32, 31, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 20, 19, 17, 16, 15, 13, 11, 10, 8, 7, 5, 3, 2];


ten=[0, 9, 17, 26, 34, 42, 51, 59, 67, 74, 82, 89, 97, 104, 110, 117, 123, 129, 135, 140, 145, 149, 153, 157, 161, 164, 167, 169, 171, 172, 173, 174, 174, 174, 173, 172, 171, 169, 167, 164, 161, 157, 153, 149, 145, 140, 135, 129, 123, 117, 110, 104, 97, 89, 82, 74, 67, 59, 51, 42, 34, 26, 17, 9];


i have fifty such tables but i just can use one table as static memory of the program, all other tables have t0 be generated during run time. kindly help if u can.
