D@n Posted September 4, 2017 Share Posted September 4, 2017 FPGA's can do some really neat things when it comes to PWM generation that micro-controllers can't do. Specifically, because they can operate at such high speeds, they can toggle the analog output line in unique fashions, and at *much* higher frequencies, than most PWM controllers. This blog article describes a simple "no-cost" change to creating better quality PWM. By "no cost" I mean that for certain interval lengths, this audio controller requires no additional flip flops, LUTs, multiplies, etc. I'm sharing it here because I've used it with the PMod AMP2 with great success.
