做项目遇到个问题，结果发现是数据类型的问题。非常生气！！！因为这么小的错误耽误了我很长很长时间。故一气之下把这个在MDK里面整合放在这里，以便警示！！！！
给自己的话：基础啊！！功底啊！！
【最常用】！！！！！
/*无符号u*/
u8----uint8_t------unsigned short char
u16---uint16_t-----unsigned short int
u32---uint32_t-----unsigned int
/*有符号s*/
s8-----int8_t-----signed char
s16----int16_t----signed short int
s32----int32_t----signed int
【下为字典，遇到了直接在下面查！！！！！！】
