For developers working with JieLi microcontrollers, understanding the JL Forced Upgrade Tool 4.0's DIP switch is essential. This manual breakdown covers how to configure communication with a PC (Bit 7), set the default state of the DP/DM pins (Bit 5), and leverage the same pins for multiple protocols.

A versatile tool for development and production on the JieLi platform.
