This commit introduces a new Modbus input register for the system's supply voltage.
- The `modbus-registers.de.md` documentation is updated to include the `SUPPLY_VOLTAGE_MV` register at address `0x00F5` within the system block.
- The `modbus_server.h` header defines the new register.
- The `modbus_server.c` implementation provides a fixed value (12300 mV) for this register.
- The `modbus_tool.py` script is updated to read and display this new supply voltage value in the UI.
This lays the groundwork for integrating actual voltage measurements in the future.
- Implement a simple, curses-based file browser to allow selecting firmware files from the filesystem.
- The selected file path is used for the firmware update process.
- Fix a visual bug where the progress bar would not reach 100% upon completion.
- Remove a leftover function that was causing a NameError.
- Add a new thread to handle the firmware update process, preventing the UI from freezing.
- The UI now displays a progress bar and status messages during the update.
- The tool reads a file and sends it to the slave in chunks.
- Add a dummy for testing purposes.
- Fix Modbus communication issues by reducing the chunk size to a safe value (248 bytes) and sending data in smaller bursts to improve stability.
- Update the README with the new features and instructions.
- Update the TUI to display all new registers from the slave, including digital I/O and system status.
- Add new menu buttons to control digital outputs and set the watchdog timer.
- Add a placeholder button for the firmware update process.
- Fix various bugs, including incorrect argument passing in Modbus calls and a module import error.
- Refactor the curses drawing loop to be state-based, eliminating screen flicker after user input.
- Add a helper function to format uptime from seconds into a human-readable string (d/h/m/s).
- Replace the basic command-line prompt with a full-screen, interactive TUI using the library.
- The new UI provides a real-time, tabular status display and intuitive, button-style menu navigation.
- Implement a consistent blue background theme for better aesthetics.
- Add a detailed with installation and usage instructions.
- Fix several bugs in the Modbus communication logic.
