基于AT32F415开发的USB便携式移动电压源 本设计支持USB PD3.0，BC1.2协议， 可通过PD/BC1.2协议使支持PD/BC1.2协议的USB电源适配器输出5V，9V，12V，15V，20V 电源给系统供电； 宽范围的输出电压，从2.7V ~ 20V可调，3A的带载能力； 输入电压电流，输出电压电流实时监测，通过320X240的TFT屏或者上位机反馈给用户； 可通过一个多
适用于嵌入式单片机的差分升级库，通用所有单片机，如stm32、华大、复旦微、瑞萨等。适合嵌入式的差分升级又叫增量升级，顾名思义就是通过差分算法将源版本与目标版本之间差异的部分提取出来制作成差分包，然后在设备通过还原算法将差异部分在源版本上进行还原从而升级成目标版本的过程。 差分升级方案不仅可以节省MCU内部的资源空间、还可以节省下载流程及下载和升级过程中的功耗。技术支持vx 18219255930
