}上面的例程是 新唐提供 UART0 输出(P06, P07), 一切正常。
但是改成 UART1 之后就不行了。

}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。

Re: 新唐 N76E003 8051 1T 单片机入坑记录
2.0版本相关工具有bug, 下载最新的工具集试一试:
https://www.nuvoton.com/hq/support/tool-and-software/software/development-tool/?__locale=en
http://www.nuvoton.com/resource-files/Nu-Link_Keil_Driver_V2.05.6815.zip

Re: 新唐 N76E003 8051 1T 单片机入坑记录
16Mhz 下明明 9600bps 和 38400bps 的误差率是一致，
但是两个批次的N76E003, 有一个批次上面两个波特率正常，
有一个批次，38400bsp 不正常， 而9600bps 正常.
void MODIFY_HIRC_166(void) // Modify HIRC to 16.6MHz, more detail please see datasheet V1.02
{
UINT8 hircmap0,hircmap1;
UINT16 trimvalue16bit;
/* Check if power on reset, modify HIRC */
if ((PCON&SET_BIT4)==SET_BIT4)
{
hircmap0 = RCTRIM0;
hircmap1 = RCTRIM1;
trimvalue16bit = ((hircmap0<<1)+(hircmap1&0x01));
trimvalue16bit = trimvalue16bit - 15;
hircmap1 = trimvalue16bit&0x01;
hircmap0 = trimvalue16bit>>1;
TA=0XAA;
TA=0X55;
RCTRIM0 = hircmap0;
TA=0XAA;
TA=0X55;
RCTRIM1 = hircmap1;
/* Clear power on flag */
PCON &= CLR_BIT4;
}
}void main (void)
{
UINT8 c;
MODIFY_HIRC_166();
set_CLOEN; //Check HIRC out wavefrom to confirm the HIRC modified
InitialUART0_Timer1(38400);
while(1)
{
if(RI)
{
c = SBUF;
RI = 0;
Send_Data_To_UART0(c);
}
}
}修正到 16.6Mhz, 两个波特率都正常了。

Re: 新唐 N76E003 8051 1T 单片机入坑记录
添加一个管脚中断程序, 用 P1 这组口, 引脚需要上拉， 可以从掉电模式唤醒，电流未测。
源码下载: Pin_Interrupt_20190715.7z
bit PIFlag;//管脚中断标志位
sbit LED=P1^5;

//设置为输入模式
P10_Input_Mode;

set_PIPS0;//选择P1为中断输入源
//Enable_BIT1_HighLevel_Trig; //高电平触发管脚中断
//Enable_BIT1_FallEdge_Trig; //下降沿
//Enable_BIT1_RasingEdge_Trig;//上升沿
Enable_BIT2_LowLevel_Trig;
Enable_BIT1_LowLevel_Trig; //低电平
Enable_BIT0_LowLevel_Trig;
LED=1;//初始化LED端口
Timer0_Delay1ms(20);
set_EPI;//开启管脚中断使能
EA = 1;//开启总中断
while(1)
{
if(PIFlag)//判定是否溢出
{
LED=0;
Timer0_Delay1ms(10);
LED=1;//灯闪烁
PIFlag=0;
ADCCON1 = 0X00;//关闭ADC
clr_BODEN;//关闭欠压检测
set_PD;// 进入掉电模式
}
}
}
//-------管脚中断中断服务程序---------
void PinInterrupt (void) interrupt 7
{
if((PIF & 0x01) == 0x01)//P10位于 0通道
{
PIF=0;//清除外部中断标志
PIFlag=1;
}
