标题: 利用工具Configuration Wizard简化C8051F的开发
Configuration Wizard 2可以为Silicon Laboratories MCU自动生成初始化代码，简化了C8051F的开发，特别适合C8051F的初学者，你不需要再去寄那么多的寄存器名字.
Configuration Wizard 2目前支持的MCU有： Support for F00x, F01x, F02x, F04x, F06x, F12x, F13x, F2xx, F30x, F31x, F32x, F33x, F34A/B, F34x, F35x, F36x, F41x, F50x, F51x, F52xA, F53xA, F54x, F55x, F56x, F57x, F58x, F59x, F70x, F71x, F80x, F81x, F82x, F83x, F90x, F91x, F92x, F93x, F98x, F99x, T60x, T61x, T63x and Si10xx MCUs
可以从SILABS网站下载到最新版的Configuration Wizard 2

下面我以一个简单的例子来说明Configuration Wizard的使用方法。
试验目的：
利用C8051F340的UART1输出“hello!my friend!”
第一步:打开Configuration Wizard 2程序，选择“C8051F340”，如下图

然后按“OK”后，自动生成C8051F340的程序框架，如下图

第二步：设置生成C代码，在菜单“Options”中设置，如下图

第三步，配置开发板上的外围设备（如UART，SPI，Timer。。。）都可以在菜单“Peripherals”中完成，如图

1，配置Port I/O,菜单“Peripherals”-“Port I/O”。此处UART1使用了P0.2和P0.3,所以配置如下：

2，时钟配置，菜单“Peripherals”-“Oscillators”，使用外部时钟22118400Hz

3，关闭WDT功能，菜单“Peripherals”-“PCA”

4，UART设置，菜单“Peripherals”-“UART”，波特率设置为9600bps。

第四步，生成代码如下：
/////////////////////////////////////
//  Generated Initialization File  //
/////////////////////////////////////
#include "C8051F340.h"
// Peripheral specific initialization functions,
// Called from the Init_Device() function
void PCA_Init()
{
PCA0MD &= ~0x40;
PCA0MD = 0x00;
}
void UART_Init()
{
SBRLL1 = 0x80;
SBRLH1 = 0xFB;
SCON1    = 0x10;
SBCON1 = 0x43;
}
void Port_IO_Init()
{
// P0.0  -  Skipped,    Open-Drain, Digital
// P0.1  -  Skipped,    Open-Drain, Digital
// P0.2  -  TX1 (UART1), Open-Drain, Digital
// P0.3  -  RX1 (UART1), Open-Drain, Digital
// P0.4  -  Unassigned,  Open-Drain, Digital
// P0.5  -  Unassigned,  Open-Drain, Digital
// P0.6  -  Skipped,    Open-Drain, Analog
// P0.7  -  Skipped,    Open-Drain, Analog
// P1.0  -  Unassigned,  Open-Drain, Digital
// P1.1  -  Unassigned,  Open-Drain, Digital
// P1.2  -  Unassigned,  Open-Drain, Digital
// P1.3  -  Unassigned,  Open-Drain, Digital
// P1.4  -  Unassigned,  Open-Drain, Digital
// P1.5  -  Unassigned,  Open-Drain, Digital
// P1.6  -  Unassigned,  Open-Drain, Digital
// P1.7  -  Unassigned,  Open-Drain, Digital
// P2.0  -  Unassigned,  Open-Drain, Digital
// P2.1  -  Unassigned,  Open-Drain, Digital
// P2.2  -  Unassigned,  Open-Drain, Digital
// P2.3  -  Unassigned,  Open-Drain, Digital
// P2.4  -  Unassigned,  Open-Drain, Digital
// P2.5  -  Unassigned,  Open-Drain, Digital
// P2.6  -  Unassigned,  Open-Drain, Digital
// P2.7  -  Unassigned,  Open-Drain, Digital
// P3.0  -  Unassigned,  Open-Drain, Digital
// P3.1  -  Unassigned,  Open-Drain, Digital
// P3.2  -  Unassigned,  Open-Drain, Digital
// P3.3  -  Unassigned,  Open-Drain, Digital
// P3.4  -  Unassigned,  Open-Drain, Digital
// P3.5  -  Unassigned,  Open-Drain, Digital
// P3.6  -  Unassigned,  Open-Drain, Digital
// P3.7  -  Unassigned,  Open-Drain, Digital
P0MDIN = 0x3F;
P0SKIP = 0xC3;
XBR1    = 0x40;
XBR2    = 0x01;
}
void Oscillator_Init()
{
int i = 0;
OSCXCN = 0x67;
for (i = 0; i < 3000; i++);  // Wait 1ms for initialization
while ((OSCXCN & 0x80) == 0);
CLKSEL = 0x01;
}
// Initialization function for device,
// Call Init_Device() from your main program
void Init_Device(void)
{
PCA_Init();
UART_Init();
Port_IO_Init();
Oscillator_Init();
}
第五步，添加main函数和串口输入函数
void uart1SendChar(unsigned char ch)
{
SBUF1 = ch;
while(SCON1&0x02==0)
;
SCON1 = SCON1&0xfd;
}

void main(void)
{
Init_Device();
while(1)
{
uart1SendChar('h');
uart1SendChar('e');
uart1SendChar('l');
uart1SendChar('l');
uart1SendChar('o');
uart1SendChar('!');
uart1SendChar('m');
uart1SendChar('y');
uart1SendChar(' ');
uart1SendChar('f');
uart1SendChar('r');
uart1SendChar('i');
uart1SendChar('e');
uart1SendChar('n');
uart1SendChar('d');
uart1SendChar('!');
}
}
第六步，keil编译完成后，下载程序，连接串口到PC，就可以看到输出。
