请问SWIN对STM8S微控制器进行编程的最小电路是多少？

我不确定你想要什么。我的猜测是：
1）编程器端的最小电路，即ST-LINK或ST-LINK / V2的替代品？我不知道。
2）SWIM引脚板上的最小电路？ AFAIK没有必要 - 有一个连接器很好，但如果你想节省成本，你可以只在测试钩上放置测试钩
3）整板的最小电路只是为了能够通过SWIM编程STM8？ AFAIK，两个或三个陶瓷电容应该做 - 一个用于osciallator，另一个用于电源。
你可能想看看相当极简主义（如果省略扩展板）STM8S001参考设计 - 只需3个电容和一些引脚头：

I'm not sure what you want to ask for. My guesses are:
1) The minimal circuit on the programmer side, i.e. a replacement for the ST-LINK or ST-LINK/V2? I don't know.
2) The minimal circuit on the board at the SWIM pins? AFAIK none is required - having a connector is nice, but if you want to save on board costs, you could just put test hooks on the pins
3) The minimal circuit for the whole board just to be able to get the STM8 programmable via SWIM? AFAIK, two or three ceramic capacitors should do - one for the osciallator, the others on the power supply.
You might want to have a look at the rather minimalist (if you leave out the extension board) STM8S001 reference design - just 3 capacitors and some pin headers:

通过ST-LINK编程设备的最小电路包括4条线。这是信号：GND，NRST，VDD，SWIM。但供电环境取决于设备的型号。
