我可能语文不是太好啥叫咋保存按键值？

ID:161164 · 发表于 2022-1-10 18:18

110行改：RunMode = IapReadByte(IAP_ADDRESS);

212行加：IapEraseSector(IAP_ADDRESS);
213行加：IapProgramByte(IAP_ADDRESS, RunMode);

可能我说法不太准确，这是个调速流水灯程序，我想保存每次调好灯速度与模式，困扰了好几天，无从下手了

ID:879080 · 发表于 2022-1-10 19:49

希望能掉电保存每次调好的模式与速度，求大师们指点。非常感谢您的参与。

看你的诉求不难，

ID:977804 · 发表于 2022-1-10 23:14

简单点，分3步。一，先做出按键能控制流水灯的速度，二，用内部eeprom读写，三，综合利用，读写第一步的按键值

ID:624769 · 发表于 2022-1-11 00:13

   IAP_TRIG = 0x46;                //Send trigger command1 (0x5a)
   IAP_TRIG = 0xb9;                   //Send trigger command2 (0xa5)

单片机型号？
0x46 是 89系列但是寄存器是  ISP_TRIG
0x5A 是 1T系列指令，寄存器是  IAP_TRIG  所以你注释和内容不同，到底是什么型号的单片机？

我这个也是stc12c2052，逻辑是：按键值加一，擦除2000h区，写入2000h区。每次上电读取2000h的值附给显示的值你搜一下我发的帖：关键字 stc12c2052的eeprom

STC12C2052AD 的 IAP启动指令是

ISP_TRIG = 0x46;
ISP_TRIG = 0xB9;

而不是你代码中的： IAP_TRIG你应该确认一下寄存器地址

多的不说了，如果如你所说： STC12C2052AD 的话：
用的是ISP 指令， ISP_TRIG = 0x46; ISP_TRIG = 0xB9;
但是，ISP 寄存器，是不同于 IAP寄存器的，
看下图修改你的 sfr 定义

ID:136485 · 发表于 2022-1-11 16:19

STC的芯片先擦除，接着写入，最后你要在什么时候读出就行
value=0x01;
IapEraseSector(IAP_ADDRESS);
_nop_();
_nop_();
IapProgramByte(0x0010, value);
这是擦除和写入，我的读出是放在上电的时候

建议楼主先分解问题，就是把程序简单化，例如一个按键，保存这个按下的反应值，例如按一下加一，否则这么长的程序哪有时间看？
