Information on the functions of the STM8S003 MCU, the roles it performs, its firmware, and the operation of its firmware are scant. My questions—these are regarding the original Edge/Edge-V—the that are left unaddressed by this lack of documentation are:
There are 128 Byte in the MCU EEPROM of Edge-V, which is divided into two parts of data, one part is used as system setting data (0x00~0x3F), and the other part is used as user data (0x40~0x7F). Some data in the system settings require a vender password to modify. The user data section needs to verify the user password to access.
The part 1 information is the factory equipment information, and users do not need to change it generally, and this part of information may involve after-sales service. Such as MAC, USID, MCU firmware version number, etc.
The MCU firmware not available for download at present.
