上面这个是工程 N76E003_BSP_Keil_C51_V1.0.5\Sample_Code\ADC_Bandgap\ADC_Bandgap.uvproj 的代码,
用于测量单片机的工作电压,
运行结果
结果显示单片机工作电压 3112mV
BG ROMMAP = 1210.500000, VDD voltage = 3112.497000
换一个电源,测算出来 4722 mV
BG ROMMAP = 1210.500000, VDD voltage = 4722.103000
说明:
N76E003 ADC的第8通道是用来测试内部的带隙电压的,
由于内部带隙电压很稳定,
不会随芯片的工作电压的改变而变化,
所以可以通过测量带隙电压,
然后通过ADC的值便可反推出VCC的电压,
从而用户可以实现自己的低压检测功能。Bandgap voltage reference,常常有人简单地称它为Bandgap。
是利用一个与温度成正比的电压与二极管压降之和,二者温度系数相互抵消,
实现与温度无关的电压基准。因为其基准电压与硅的带隙电压差不多,
因而称为带隙基准。实际上利用的不是带隙电压。
现在有些Bandgap结构输出电压与带隙电压也不一致。

_sdcc_external_startup (void)

mov 0xC7, #0xAA ; [0xC7] = 0xAA
mov 0xC7, #0x55 ; [0xC7] = 0x55 {'U'}

以下为是写时效保护寄存器的正确和错误范例:

MOV TA,#55H ;3 clock cycles

MOV TA,#0AAH ;3 clock cycles

NOP ;1 clock cycle
ANL BODCON0,#data ;4 clock cyclesExample 3,
MOV TA,#0AAH ;3 clock cycles
MOV TA,#55H ;3 clock cycles
MOV WDCON,#data1 ;3 clock cycles
ORL BODCON0,#data2 ;4 clock cyclesExample 4,
MOV TA,#0AAH ;3 clock cycles
NOP ;1 clock cycle
MOV TA,#55H ;3 clock cycles
ANL BODCON0,#data ;4 clock cycles在第一个例子中,写保护位在三个时钟周期窗口关闭之前完成。然而,在例2中,BODCON0的写入并
没有在时效访问窗口打开时完成,操作完这些指令后,BODCON0的值不会有变化。示例3中,WDCON
写入成功,但对BODCON0访问超过三个机器周期窗口,因此BODCON0值不会改变。例4,第二次写
55H对应第一个AAH写入时间超过了3个机器周期,时效访问窗口打开失败,所以后面的写入全部无效。

_sdcc_external_startup会在启动后调用,里面可以做一些初始化的操作,其中的汇编是直接从keil n76e003 bsp的启动文件里面扣出来的,作用是关闭POR功能
翻了一下手册, 涨知识了:
重要说明:
由于N76E003 POR侦测电压落在1.3V 至 1.5 V范围IE之间,当N76E003进入掉电模式后,再次唤醒
时,N76E003的内核电压可能低于1.5 V,此时可能会触发POR 动作,造成芯片复位。为避免这种现
象,建议当每次电源上电正常运行程序之后,关闭POR模块。解决方法:
由于POR是用于判断VDD上电状态,当上电状态结束后由LVR来判断电源状态,故建议当稳定上电后,
关闭POR,下面说明如何关闭POR功能。
寄存器PORDIS(FDH)可以用于关闭POR功能。关闭POR
对PORDIS寄存器先写入5AH,再写入A5H可以关闭POR功能请严格按照如下步骤关闭POR功能:
sfr PORDIS = 0XFD; TA =0XAA; TA= 0X55; PORDIS = 0X5A; TA=0XAA; TA=0X55; PORDIS = 0XA5;

SDCC其实蛮好用的,编译速度很快,特别是linux环境下,windows下面速度也挺快。用好SDCC需要一些技巧,比如你得比较熟悉makefile,以及SDCC里面的一些小坑。我个人做的很多项目都是使用SDCC,除了51单片机外,SDCC也支持STM8的。下面我分享一个新塘单片机的工程文件给大家参考一下

下面说一说eclipse对比keil的优势,其实最主要的是编辑代码的增强,keil特别是C51版本的,基本还停留在上世纪的编辑风格,和windows自带的记事本强不了多少。eclipse具有代码提示、关键词特殊颜色、全局修改变量等等功能,也可以直接搭配git
SDCC时至今日还在活跃的更新,说明还是有一部分人在用的。SDCC里面的一个大坑是关于中断函数,据我个人测试中断函数必须在main函数之前被声明或者直接编写,不然就无法进中断,切记。SDCC编译固件时如果工程里面有较多的无用代码,它也会直接编译到hex里面的,这个问题困扰了我好久,一直没有得到解决。所以如果空间紧张,建议注释掉一些无关的代码,避免代码空间膨胀

关于中断这个当初我也是被坑了好久,后来才发现这个其所在sdcc的手册内是有描诉的,看他的意思除了能放在main对应的那个c文件内,在main的头文件包含也是可以的,不过后面那个场景我没试过。
SDCC allows interrupt service routines to be coded in C, with some extended keywords.
void timer_isr (void) __interrupt (1) __using (1)
{
...
}
The optional number following the __interrupt keyword is the interrupt number this routine will service. When
present, the compiler will insert a call to this routine in the interrupt vector table for the interrupt number specified.
If you have multiple source files in your project, interrupt service routines can be present in any of them, but a
prototype of the isr MUST be present or included in the file that contains the function main. The optional (8051
specific) keyword __using can be used to tell the compiler to use the specified register bank when generating code
for this function.
