加载extEEPROM编译错误 about arduino-for-keil HOT 11 CLOSED

对比两个库唯一区别是外部调用的声明这个地方
//extern"C"{
#include "Arduino.h"
//}
#include "Wire.h"

@whqsz 新的extEEPROM库已上传，而且增加了示例

去除 extEEPROM.h 的 "extern"C"{}" 即可

感谢你的回复，问题已经解决。
目前对DigitalFilter.h调用上还是弄不明白，最好提交一份demo参考，让我们新手少走弯路。
谢谢！

好的，我稍后会更新例程

@whqsz 数字滤波器例程已更新

遇到一个问题，当单片机不外接8M晶振系统默认运行速度很慢，项目核心库中暂时没找到启用内部64M频率的函数，但我只找到这个函数来设置内部晶振。我希望能尽量使用本项目自身封装函数。感谢！

使用内部时钟源属于特殊需求，通用性不强，所以我没有在项目里封装，用标准库就可以了

from arduino-for-keil.

在配置完时钟源后，调用Delay_Init()，让Systick自适应

from arduino-for-keil.

这两次更新 timer.c
只要在main中加上定时器中断 程序运行卡在setup过不去 进程追踪停止while(System_ms < Stop_TimePoint);这行
/**

• @brief 毫秒级延时
• @param ms: 要延时的毫秒数
• @RetVal 无
  */
  void delay_ms(uint32_t ms)
  {
  uint32_t Stop_TimePoint = System_ms + ms;
  while(System_ms < Stop_TimePoint); 停在这里
  }

项目只用到Wire库

#include "FileGroup.h"
...
...
int main(void)
{
SetSysClockTo64Mhz();
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
GPIO_JTAG_Disable();
//SysClock_Init(F_CPU_64MHz);
Delay_Init();
//ADCx_Init(ADC1);0
TimerSet(TIM2, 1000, Onems); //1毫秒定时器 这里
TIM_Cmd(TIM2, ENABLE); 这里

setup();
for (;;)loop();

@whqsz 加我Q吧

是不是在中断里调用delay了
