MODDMA DAC
I am use lpc1768 with moddma to create a sine wave. I am using the example from the own library. I have configured the maximum refresh rate to 1 MHz as the user manual says it is the maximum. It is working well but I can see that from the swap from buffer0 to buffer1 is creating a crossover, provably generated by the time in switching buffers, not creating a perfect sine wave.
How could I fix this?
