简介:
The STM32F407 is capable of generating sinusoidal waveforms with adjustable frequencies. A DAC, activated by a timer, outputs a sine wave consisting of 32 data points per cycle. Testing has demonstrated that this configuration yields a waveform with remarkably low distortion. Further enhancements in precision could be achieved by increasing the number of data points generated during each cycle.
