Standalone proportional-integral-derivative regulator with the ability to be controlled via Wi-Fi (acts like UDP server).
The app relies on the official ESP-IDF framework. Instruction set of the regulator itself can be find in commandmanager.h file or in pid-controller-gui repository. Supports both IPv4 and IPv6 networks.
udp_server_task serves main UDP server and constantly listening for incoming messages. They are then passed to commandmanager module (process_request() function) and the prepared reply is sending back to the client.
_stream_task is an internal task only active when stream of process variable and controller output values is requested.
pid component performing the main PID algorithm.
Refer to ESP-IDF documentation for help on compile & run processes. Generally, to build, flash and run built-in UART monitor you should invoke:
$ make -j8 flash monitorAlternatively, you can apply tasks of VSCode editor that have been used during development by me. They are placed in .vscode/tasks.json file.
The app can be easily paired with pid-controller-gui PC utility out-of-the-box.
- Better port to more advanced PID engine such as MiniPID and use more classy architecture for managing PID configuration both in commandmanager and in dedicated task
