Iot duty cycle

WebFor ESP32, MicroPython allows you to specify PWM frequency from 1KHz to 40 MHz. The duty cycle resolution can be from 1 bit to 16 bits. To avoid any errors in PWM generation, first determine the desired duty cycle resolution. Higher will be the duty cycle resolution, more precisely, output voltage levels could be controlled. Web5 mei 2024 · PSM allows these IoT devices to negotiate an extended sleep period (hours or days) with the network and avoid being paged during that sleep cycle. If there is any traffic that arrives for the device during the sleep period, the traffic is buffered in the network (at least the last 100 bytes) and delivered when the device becomes ACTIVE.
