Introduction: Using the mem32 function, for the problem of low PWM frequency accuracy in MM32 micro python, we can improve the PWM frequency accuracy by readjusting the ARR. Key words: PWM, MM32, micropathon, mem32   § 01 MM32 PWM output Advantages and disadvantages of version 1.1   in Micro Python transplantation ...

I Hardware scheme This design is mainly divided into five functions: temperature measurement, humidity and PM2 5 and CO and send information and alarm. With the ingenious combination of these functions with home, we already know how to realize the five separate functions. Now we need to systematically feed back the five functions through singl ...

The PWM pulse width signal is used to realize the independent key S7 control to control the brightness change of L1 indicator. The frequency of PWM pulse width signal is 100HZL1 is off after the system is powered onThere are four brightness modes when L1 is powered on, namely, complete off, 10% brightness, 50% brightness and 90% brightnessPres ...

engineering structure The codes related to time slice scheduling are located in the scheduler and Task files in the scheduler directory. The original clock of anonymous flight control is provided by the external interrupt realized by the 1ms pulse output by the sensor. In order to make the time slice scheduling algorithm can be used in genera ...
