kinetis入门之——UART
0赞1、点“文件->新建->bareboard project”出现下面对话框:
为工程起个名字(该示例为k10_uart_pe),点“下一步”,出现:
选择你所用的芯片型号即可。点“下一步”,出现:
“Connetion to be used”中先选我们先前建好的“USBDM K10X256”,点“下一步”,一直点“下一步”直到出现:
选“Processor Export”,点“下一步”,出现:
选实际用到的芯片(我用的是144-pins LQFP),点“完成”,出现:
等待上面对话框消失,一个工程就建好了。
双击窗口左边的“Communication->Serial_LDD”添加一个“Serial_LDD Bean”,如下图:
出现:
选“Distinct mode”,点“确定”,出现:
上述串口配置完之后还需配置一下时钟,出现乱码等情况是由时钟不准引起的,用外部4MHz晶体谐振器就不会有乱码了。方法如下:
选择“ProcessorExport.pe->Cpus”下面的CPU型号,如下图
配置成下面的样子:
按上图配置,点“项目”->“Generate Processor Export Code”如下图:
下面是参考代码:
ProcessorExpert.c
/* Including needed modules to compile this module/procedure */
#include "Cpu.h"
#include "Events.h"
#include "AS1.h"
/* Including shared modules, which are used for whole project */
#include "PE_Types.h"
#include "PE_Error.h"
#include "PE_Const.h"
#include "IO_Map.h"
/* User includes (#include below this line is not maintained by Processor Expert) */
volatile bool DataReceivedFlg = FALSE;
char OutData[] = "Hello world";
char InpData[10];
LDD_TError Error;
LDD_TDeviceData *MySerialPtr;
void main(void)
{
/* Write your local variable definition here */
/*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
PE_low_level_init();
/*** End of Processor Expert internal initialization. ***/
/* Write your code here */
/* For example: for(;;) { } */
MySerialPtr = AS1_Init(NULL); /* Initialization of AS1 component */
for(;;)
{
Error = AS1_SendBlock(MySerialPtr, OutData, sizeof(OutData)); /* Send block of characters */
}
/*** Don't write any code pass this line, or it will be deleted during code generation. ***/
/*** Processor Expert end of main routine. DON'T MODIFY THIS CODE!!! ***/
for(;;){}
/*** Processor Expert end of main routine. DON'T WRITE CODE BELOW!!! ***/
} /*** End of main routine. DO NOT MODIFY THIS TEXT!!! ***/
/* END ProcessorExpert */
