ESP8266_PWM VS esp-idf-lib

Compare ESP8266_PWM vs esp-idf-lib and see what are their differences.

ESP8266_PWM

This library enables you to use Interrupt from Hardware Timers on an ESP8266-based board to create and output PWM to pins. It now supports 16 ISR-based synchronized PWM channels, while consuming only 1 Hardware Timer. PWM interval can be very long (uint32_t millisecs). The most important feature is they're ISR-based PWM channels. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware PWM channels, using interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's necessary if you need to measure some data requiring better accuracy (by khoih-prog)

    Biggest issue I can think of is trying to do PWM _and_ WiFi work simultaneously on an esp8266. If you have, say, an esp8266 serving up a small webpage for control and don't want to add an external PWM board then you might notice intermittent issues. This is more obvious if you're controlling something like a lighting ballast that's PWM controlled.

    Of course now that I'm looking around I see https://github.com/khoih-prog/ESP8266_PWM which seems promising (subdivides the second of two available hardware timers to allow PWM that isn't sensitive to other running code). So there's multiple workarounds (libraries, breakout boards) besides upgrading to an esp32.
