这次要做的是将之间在 ATmega328P 上测试过的方案在 PIC16F13145 上复现一下，上次的帖子在这里 - https://bbs.21ic.com/icview-3376522-1-1.html

L6234 运行的核心功能来自 PIC MCU 的 GPIO，具体来说，就是每一步有一个管脚输出高，相对应的另一个管脚输出低，我先将基础的 GPIO 程序发到回复中，重要的是要注意的几个细节。

要注意的细节是：
1、PIC MCU 要能正常运行，首要的是“ Configuration Bits”的设置，这个设置最重要的有两项：时钟源的选择（本例中选用内部低速振荡器）、关闭看门狗定时器（默认为开）。
2、每一个管脚在重启后默认的都是模拟模式为开，用户要自己给相应的寄存器清零，确保关闭这项功能。

? 没明白你的意思。

? 没明白你的意思。

我用的工具组合是：

MPLAB X IDE v6.15
XC8 v2.50
PIC16F1xxxx_DFP(1.25.389)

IDE 提示 MCC 不可用，我就手动设置了一下。
