STC51和STM32下载器,这次缩小体积加入小体积聚合物锂电池,加入硬件手动冷启动下载开关,希望做到全部STC单片机的程序下载,整合了STM32单片机TTL一键自动下载电路.
因为是之前的电路再整合,电路工作原理就不再说明了,下面把STC51下载器和STM32一键下载器链接贴出来:

STM32一键下载器: https://maker.lceda.cn/p/583703056a/ch340c-stm32f103c8t7
下面主要讲解一下,锂电池充电电路和升压电路:
红圈1 TP4057锂电池充电电路,这个芯片带反接保护
红圈2 PS7516锂电池升压电路,输出电压设定不要高于5V
红圈3 插在USB充电时自动关闭锂电池升压电路
红圈4 这是用开关控制锂电池升压,作用是用于在不充电时关闭5V升压来节省锂电池的电量.
下载器中加入了几个拨动开关, SW1是STC51脱机下载器的升级开关,
SW2是STC51下载器给外部单片机自动下载和手动下载切换开关.
SW3是脱机下载触发开关.
SW4是用于选择给外部STC51单片机是5V供电还是3V供电切换开关.
SW5是给STC51单片机手动冷启动下载开关.
