This example is found in API-DLL\FP-GP-ARM-Demo-Py in the installation directory.

  • If running 64-bit Python (default installation), use the x64 ARM-win setup (X-ProARM-xvxx-Setup_x64)

  • If running 32-bit Python, use the x86 ARM-win setup (X-ProARM-xvxx-Setup_x86)

  • For Linux the default Python installation will work with the amd64 or armhf builds.

Any application using the library will call most of the following functions. First, any one adapter is found, and initialized. Assuming at least one adapter was found (F_OpenInstancesAndFPAs returns > 0), the config and code files are loaded to select the MCU and data to be programmed. Finally, the procedure F_AutoProgram will run the full programming sequence of Erase, Blank Check, Write, Verify, and optionally Lock the MCU.

Running the aforementioned code snippet with Python 3.8.3 produces the following result:
