对于工程师博客来说，经常都需要在博客中插入代码。如何让插入的代码看上去友好又整洁呢？ChinaAET的博客代码插入功能能为您解决这个问题。

发布博客的时候点击编辑框上部的这个按钮，剩下的工作根据指示完成就可以啦。

举例插入bluehacker的《Freescale MCF52211 UART演示程序》一文中的代码，如下所示，看上去是不是非常顺眼呢？

#include "support_common.h" /* include peripheral declarations and more */ #if (CONSOLE_IO_SUPPORT || ENABLE_UART_SUPPORT) /* Standard IO is only possible if Console or UART support is enabled. */ #include #endif void uart0_init(unsigned long baudrate) { register uint16 div; MCF_GPIO_PUAPAR =0x05; /* * Reset Transmitter */ MCF_UART0_UCR =MCF_UART_UCR_RESET_TX; /* * Reset Receiver */ MCF_UART0_UCR = MCF_UART_UCR_RESET_RX; /* * Reset Mode Register */ MCF_UART0_UCR = MCF_UART_UCR_RESET_MR; /* * No parity, 8bit data */ MCF_UART0_UMR1=(0 | MCF_UART_UMR_PM_NONE | MCF_UART_UMR_BC_8 ); /* * 1bit stop */ MCF_UART0_UMR2=(0 | MCF_UART_UMR_CM_NORMAL | MCF_UART_UMR_SB_STOP_BITS_1); /* * Set Rx and Tx baud by SYSTEM CLOCK */ MCF_UART0_UCSR = (0 | MCF_UART_UCSR_RCS_SYS_CLK | MCF_UART_UCSR_TCS_SYS_CLK); /* * Mask all UART interrupts */ MCF_UART0_UIMR = 0; /* set baud rate */ div=(uint16)(60000000L/(32*baudrate)); MCF_UART0_UBG1=(unsigned char)(div>>8); MCF_UART0_UBG2=(unsigned char)(div&0x00ff); /* Enable Tx/Rx*/ MCF_UART0_UCR = (0 | MCF_UART_UCR_TX_ENABLED | MCF_UART_UCR_RX_ENABLED); } void uart0_putchar(unsigned char c) { /* Wait until space is available in the FIFO */ while (!(MCF_UART0_USR & MCF_UART_USR_TXRDY)) { }; /* Send the character */ MCF_UART0_UTB = c; } unsigned char uart0_getchar() { /* Wait until character has been received */ while (!(MCF_UART0_USR & MCF_UART_USR_RXRDY)) { }; return MCF_UART0_URB; } void uart0_putstr(unsigned char *str) { while(*str!=0) { uart0_putchar(*str++); } } int main(void) { int counter = 0; unsigned char c="0"; #if (CONSOLE_IO_SUPPORT || ENABLE_UART_SUPPORT) printf("Hello World in C from MCF52211 derivative on MCF52211 board\n\r"); fflush(stdout); #endif uart0_init(9600); uart0_putstr((unsigned char*)("MCF52211 Uart0 test start\n")); for(;;) { c=uart0_getchar(); uart0_putchar(c); counter++; } }
