LUT tables don't have to be the full waveform, either. I generated a sine wave form a half a sine LUT with no issues, just read it forwards and backwards. This works better for some waveforms than others, obviously.
I was using flowcode as I'm not a programmer, and my 16f88's were not very happy about what I was trying to do. I had meant to try generating waveforms from a 90 degrees of a cycle: Read table, read table backwards, read table but subtract from max value( say 1), and then invert that.
What are people here using to program their PIC's, and what's a good resource for it?
Also, I had a freind play a note on the Saxaphone and I generated a wavetable from a cycle of that. I think I've the file, but I've no longer access to Matlab. If I can find the LUT or something else with a wavread function. Might be fun to do some of guitar, piano, trumpet, maybe a pair of 5ths etc. etc.
What would two notes a semitone apart sound like as an LFO?
