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。

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。
