Graphical User Interface for Serial Communication

Description

SerialUI provides a graphical interface to send and receive text from the serial port, including a serial plotter for displaying numerical data. It offers features beyond the Arduino IDE Serial Plotter.

From an ESP32 we can retrieve about 400kBytes/s. For simple simulated data more than 20k samples/second can be retrieved and plotted.

BLESerialUI is equivalent to SerialUI but uses the Nordic Serial UART on a BLE connection (Experimental)

Installation Requirements

One liner Windows: - pip3 install pyqt5 pyqtgraph numpy pyserial markdown wmi bleak qasync

One liner Linux: - pip3 install pyqt5 pyqtgraph numpy pyserial markdown pyudev bleak qasync

• pyqt5 or pyqt6 user interface
• pyqtgraph display
• numpy data gathering and manipulation
• pyserial serial interface
• markdown help file
• wmi on Windows for USB device notifications
• pyudev on Linux for USB device notifications
• qasync and bleak for bluetooth communication

Installation of PyQt5/6 has its own dependencies. If it fails, read the suggested solution in the error messages.

The main programs are SerialUI.py and BLESerialUI.py. The use files in the assets and helper folders.
