本文件是通过IAR for ARM软件调试通过的PWM 音乐输出程序代码(This document is the debug output PWM music program code by IAR for ARM software)

此资料包括LTC68xx驱动库、arduino开发BMS资料及其他资料介绍，此开发资料主要用于BMS系统开发，主要是LTC6811的使用（带C库文件及芯片datasheet），只验证了LTC6811库驱动(This information includes LTC68xx driver library, Arduino development BMS data and other information. This development information is mainly used for BMS system development, mainly for the use of LTC6811 (with C library files and chip data sheet), which only verifies the LTC6811 library driver.)
