Recently I saw a new book about UCOSII online. What I want to ask is, do you use it in your work? My conclusion is that it is not used at all in work. Why? Just imagine, a thing that can be executed i...
It is probably that a PWM wave of a certain frequency is generated by a clock. Using FPGA can get a more perfect waveform, but if only a CLK wave is provided, F5529LP can do it completely. [cpp] view ...
