摘要：是采样速率低于5Msps (每秒百万次采样)的中等至高分辨率应用的常见结构。SAR ADC的分辨率一般为8位至16位，具有低功耗、小尺寸等特点。这些特点使该类型ADC具有很宽的应用范围，例如便携/电池供电仪表、笔输入量化器、工业控制和数据/信号采集等。顾名思义，SAR ADC实质上是实现一种二进制搜...

摘要：stm32的swd接口的烧写协议是否公开的呢？需要用一台好的示波器来抓才能有足够的存储深度，保证你能够过滤掉那个该死的50clock。按照Arm的手册，每次转换发送方都需要一个TNR---但是我观察JLINK的波形却没有那个该死的TNR。手册中说异步SWD需要，同步不需要----或者相反，但是我没有...
