Does DAC support implemented?

Hi,
Does DAC support implemented?

There is an analog output available on many PCF8591 boards, that can be enabled in the settings of the plugin. The output can then be controlled by the `analogout,<value>` command, where <value> can be in the range 0..255. Have used that to test the analog output, by connecting it to one of the analog inputs of that board
Haven't found other options yet, but using a R/C combination connected to a GPIO pin and using the 'pwm' command, you can have a, somewhat crude, analog output.

What about this? https://github.com/letscontrolit/ESPEas ... 46_DAC.ino
Someone try?

That plugin is on the PluginPlayground only, and will need some work to be able to run on current mega branch.

I've reserved PluginID P152 for this plugin on the Github issue tracker. Will try to add that, as it doesn't seem too difficult to adapt. We're locking out the ESP8266 though, as the plugin uses an ESP32-only feature DAC1 and DAC2 (and ESP32-S2 uses different GPIO pins than ESP32, and the ESP32-C3 doesn't support DAC output at all...)

I have created Pull Request #4600 to migrate this plugin from the PluginPlayground to the Mega branch. A Github Actions build is running, you can download here, once the build is ready, for testing. You will need a (free) Github account, and logged in, to be able to download.

I found this interesting Instructables article, that compares the DAC output to a simple RC PWM to Analog converter.

Dude, you're awesome

I've initiated a fresh build (with the latest merged code in it) in this GH Actions run. Can you update (you will need a free GH account to download), test and report your findings here?
