I’ve been trying to do some simple loops with the lpc1768. Due to form factor, I’m using the mbed board.
The issue is extremely poor performance; trying to drive the dac I’m getting about 1 cycle every two seconds, generating a sine wave. I took everything out of my code save the loop in main (just to test) and
cannot explain this terrible performance. On a different form factor lpc1768 using keil, the performance is great, and I can do 8k sine waves.
Does anyone have any feedback about this? I’d like to dump the mbed.h and compile just my keil code, but I get a lot of duplicate defines, (__ARM, for example) that don’t exist in my code.
Has anyone else had these performance issues?
