Introduction to the tools

ChipType: the chip type, selected according to the type of product used WorkMode: Software mode, currently available in Develop mode and Factory mode, as follows: Develop mode uses the firmware absolute path and only supports single-chip product burning. Factory mode uses a relative path, and it is recommended that the firmware to be burned be placed with the. EXE file is automatically saved locally when it is closed after configuration. When Factory mode is turned on, the interface is locked and you need to click the LockSettings button to enable editing. Prevent misoperation of the mouse.
