PWM On The Lattice ICEStick

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

Swapping bits improves performance of FPGA-PWM counter

When you need some analog outputs and you have an FPGA in your system, you probably choose to use a PWM module and a simple lowpass filter such as those in Figure 1. The output of the FPGA is ...
