### Is it possible to read code (or EEPROM) memory out of a chip? ### Is it possible to read code (or EEPROM) memory out of a chip?
By design, this is not possible with STC's bootloader protocols. This is considered a security feature by STC. There is no known workaround at this time. See issue #7 for more details and discussion.
