为什么PIC12F675没有睡觉？

问答对人有帮助，内容完整，我也想知道答案 0 我正在尝试为电池操作的设备建立电源控制器。我选择PIC12F675。这个想法是将PIC置于睡眠模式。用秒表计时每秒唤醒它。检查引脚状态，决定是否接通或断开。决策代码工作正常。但是PIC不睡觉。它看起来像PIC跳过睡眠（）宏。在问这个问题之前，我做了一个深入的研究并测试了我发现的所有东西。下面是配置：所有引脚都是IO。无外部晶体，无复位。没有浮针。我没有观察到任何睡眠情况，也重置条件。问题是我做错了什么PIC12F675没有睡觉？编程平台：MPLABX+XC8（最新版本免费）+PICIT3[&字体]配置。以上来自于百度翻译以下为原文 I'm trying to build a power controller for a battery operated device. I choose PIC12F675. The idea is putting pic in sleep mode. Wake it up with Watchdod timer approx each second. Check pin states, decide whether to switch on or off. The decision code is working as expected. But PIC does not sleep. It looks like PIC skips SLEEP() macro. Before asking this question i've made a deep research and tested everything I found. So here are the configuration: ---------- Vdd \|1 8\| GND/VSS Dock test pin(out) GP5 \|2 7\| GP0 (in) Batt Measure Power Fet Drive(out)GP4 \|3 6\| GP1 (in) Batt Measure reference voltage Charge Status (in) GP3 \|4 5\| GP2 (in) Dock sense ---------- All pins are io. No external crystal, no reset. No floating pin. I do not observe any sleep condition, also reset condition. The question is what am i doing wrong that the PIC12F675 is not sleeping?

答案对人有帮助，有参考价值 0 我在Meal.C文件上做了排版错误。其实PIC睡觉，但我不能意识到它正在睡觉。因为它的睡眠时间是18Ms，这条线应该是：以上来自于百度翻译以下为原文 I made a typographic error on main.c file. Actually pic sleeps but I cannot realize that it was sleeping. Because it was sleeping for 18ms. This line: OPTION_REGbits.PS = 0x110; //postscaler 1:64 ^ Should be: OPTION_REGbits.PS = 0b110; //postscaler 1:64 ^
