FlashPro-430 python example running on Raspberry Pi - 64-bit (arm64 build, RPi4 model B) This example is found in /libfpgp430-5.8.0_arm64/Python-demo in the installation directory (linux unzipped package). 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. | Code Block |
