I am using ST micro's STM32F103 chip with their AN2812 development code. It uses a PWM output, resulting in low-quality sound. Can I just use a scaled version of the PWM to drive a DAC? (i.e. is the output linear, or is there shaping to make the PWM output work?) Any feedback, links or pointers would be greatly appreciated.
