如何将字符发送出模拟器

嗨，大家好：
 
 
我有几个关于STM8的问题。我在STVD中使用Cosmic编译器并尝试使用IDE附带的模拟器。我能够运行一些简单的程序，但我想做的是将字符从模拟器导出到主机。
 
到目前为止，我追求了一些途径。一个途径是使用printf打印到控制台。以下是我用的代码......
 
#include''stdio.h''
#include''iostm8a.h''
 
#define TRDE 0x80 /​​ *发送就绪位* /
 
#define rim（）_asm（''rim''）
 
/ *输出一个字符输出
 * COSMIC Software版权所有（c）1998
 * /
 
/ *输出一个字符
 * /
char putchar（char c）
{
 char VCAST_OUTCH = c;
 if（c ==' n'）
 {
 / *把' r'放到硬件这里* /
 while（！（USART_SR＆amp; TRDE））; / *等待READY * /
 
 USART_DR =' r'; /* 发送 */
 }
 / *把c放到这里硬件* /
 while（！（USART_SR＆amp; TRDE））; / *等待READY * /
 
 USART_DR =' r'; /* 发送 */
 
 返回（c）;
}
 
主要（）
 {
 
 USART_BRR1 = 0xc9; / *波特率参数* /
 USART_CR1 = 0x00; / *字长* *参数
 USART_CR2 = 0x2c; / *中断参数* /
 轮缘（）; / *授权中断* /
 printf（''hello world''）;
 printf（''再来一次！''）;
 }
 
我可能没有完整的代码，因为我不知道如何将这些字符发送到控制台。如果是这种情况，有人可以告诉我吗？
 
研究这个论坛，我也意识到在发布说明中，ST报告说STM8模拟器没有实现外围设备，所以另一方面，可能没有任何方法可以进入该控制台窗口。
 
因此，我尝试将发送到putchar的字符存储到要通过调试器（gdb）保存在主机上的文件中。我的想法是做类似的事情：
 
fopen number myfile.txt
watch putchar（）：char_being_written {将char放入文件的操作}
走
fclose file_number
 
我试图fopen 1 out.txt，但是GDB只报告了'''fopen error''而没有太多细节。我也不确定访问将char值写入文件的操作 - 在其他环境中，你显然可以做fwrite，但在这里似乎并非如此。
 
有人可以给我一些指示吗？
 
谢谢！

Hi everyone:


I have a few questions about STM8. I am using the Cosmic compiler within STVD and trying to use the simulator that comes with the IDE. I am able to run some simple programs, however what I would like to do is to export characters out of the simulator to the host.  

I pursued a few avenues so far. One avenue was to use printf to print to the console. The following is the code I used...  

#include ''stdio.h''  
#include ''iostm8a.h''  

#define TRDE 0x80 /* transmit ready bit */  

#define rim() _asm(''rim'')  

/* PUT A CHARACTER TO OUTPUT  
* Copyright (c) 1998 by COSMIC Software  
*/  

/* output a character  
*/  
char putchar(char c)  
{  
char VCAST_OUTCH = c;  
if (c == 'n')  
{  
/* put 'r' to hardware here */  
while (!(USART_SR & TRDE)); /* wait for READY */  

USART_DR = 'r'; /* send it */  
}  
/* put c to hardware here */  
while (!(USART_SR & TRDE)); /* wait for READY */  

USART_DR = 'r'; /* send it */  

return (c);  
}  

main()  
{  

USART_BRR1 = 0xc9; /* parameter for baud rate */  
USART_CR1 = 0x00; /* parameter for word length */  
USART_CR2 = 0x2c; /* parameters for interrupt */  
rim(); /* authorize interrupts */  
printf(''hello world'');  
printf(''hi again!'');  
}  

I might not have a complete code since I don`t know how to send these characters to the console. If this is the case, could someone kindly let me know?  

Researching on this forum, I also realized that in the release note, ST reports that the STM8 simulator does not implement peripherals, so on the other hand, there might not be any way to get to that console window.  

So, I tried to store characters sent to putchar to a file to be saved on the host through the debugger (gdb). My idea is to do something similar to this:  

fopen number myfile.txt  
watch putchar():char_being_written { operation to put the char in the file }  
go  
fclose file_number  

I tried to do fopen 1 out.txt, but GDB just reported `''fopen error'' without much details. I am also unsure of the operation to access to write the char values to file - in other environments, you can apparently do fwrite, but it does not seem to be the case here.  

Could someone give me a few pointers?  

Thanks!

嗨，
 
 
在库stdio中定义的printf（）函数调用putchar（）函数在控制台上发送数据。在你的情况下你已经个性化了putchar（）函数来向COM发送字符（超级终端）
要读取数据，您需要个性化getchar（）函数。
您可以参考STM8S FWLibrary中的USART_Printf示例。

Hi,


The printf() function as it defined in the library stdio call the putchar() function to send data on the console, In your case you have personalized the putchar() function to send characters to the COM (HyperTerminal)  
To read data you need to personalize the getchar() function.  
You can refer to the USART_Printf example in the STM8S FWLibrary.
