from-file ：一个文件名，作为原始比对文件的文件名；to-file ：一个文件名，作为目的比对文件的文件名；注意，from-file 或 to-file 可以 - 取代，那个 - 代表“Standard input”之意。-b ：忽略一行当中，仅有多个空白的差异（例如 "about me" 与 "about me" 视为相同 -B ：忽略空白行的差...

The fprintf() function formats and writes output to astream. It converts each entry in theargument list, if any, and writes to the stream according to the corresponding format specification in theformat-string. The fprintf() function cannot be used with a file that is opened usingtype=reco...
To use printf() in our program, we need to include stdio.h header file using the #include <stdio.h> statement. The return 0; statement inside the main() function is the "Exit status" of the program. It's optional. Example 2: Integer Output #include <stdio.h> int main() { int ...
int fprintf ( FILE * stream, const char * format, ... ); int sprintf ( char * str, const char * format, ... ); fprintf 是将格式化后的字串输出到 FILE * 指定的 stream 中. sprintf 将格式化后的字串输出到 由 str 指向的缓冲中,会自动在字串结尾输出 NULL 字符.若成功,两函数均返回输出...

主要是调用printf，编译相关库故程序就会很大，导致溢出。你可以看看这篇博客，应该可以解决你的问题，解决STM8空间太小，使用不了printf串口打印。
