Recently in the study of STM32 PWM output, because the hands do not have an oscilloscope, so in accordance with the Wildfire tutorial using software simulation, using MDK5 Logic Analyzer to observe the waveform, the front all the way smoothly, in the logic Analyzer to open the Add Signal, the problem occurred--unknown signal! The signal cannot be added in. In the Baidu Library to see a MDK460 related problems of the solution, so I hold a try attitude, tried a try, the result is very good, so thought and share with you.
1. Error hints
2, the solution, according to the following control to modify the relevant parameters can be
Before modifying, the default parameters are modified, the parameters
I hope to be able to help the people who encounter this problem, hoping to pass the Great God Light spray.
Do stm32 software simulation in Keil, view output PWM waveform, specify IO port signal in Logic Analyzer, "Unknow signal" appears
