- GUI and command-line operation
- Erase, read, program and compare functions
- Automatically adds the required checksum to the firmware image
- Safe to use: does not allow to lock you out of ISP by default
- Info functions: reading of Part ID, UID, boot code version, etc
- Wait function: polls the LPC81x until the ISP becomes available
- Option to automatically run the firmware after flashing
A Windows executable is in lpc81x-isp-windows.zip so Windows users don't need to install Python and respetive modules.
Alternatively, install Python from https://www.python.org/.
This tool is compatible with Python 3.6+
The tool requires the following 3rd party python modules:
- pyserial
- intelhex
- tk (optional)
tk is required for GUI (graphical user interface] usage; but not necessary for command line usage.
This tool is designed for command-line usage in a makefile, but also has a simplistic GUI.
For programming a HEX file via GUI just launch the application without any command line arguments.
For programming a HEX file from the command line, use the following example:
lpc81x_isp.py --wait --flash <firmware.hex> --run --port <usb-to-serial>
If the LPC MCU is not in ISP mode yet, the tool will wait and periodically probe the chip. After flashing the firmware, it will execute it.
Run lcp81x_isp.py --help to see all available command line arguments.
How to build the Windows executable using pyinstaller:
pip install pyinstaller
pyinstaller lpc81x_isp.spec
How to build the Windows executable using py2exe:
python setup.py py2exe
Output is in the dist/ directory
