argument of type "unsigned char const *" is incompatible with parameter of type "unsigned char *"

IAR编译器
我在.H文件中写了const  unsigned char  default_mode[3]={0x00 , 0x00 , 0x00};
用void write_BL6523_reg(unsigned char reg,unsigned char dat[3])；函数调用。write_BL6523_reg(MODE, default_mode);
但是报错argument of type "unsigned char const *" is incompatible with parameter of type "unsigned char *"

你default_mode是const unsigned char  ，函数里面 unsigned char  不能这要调用的，会报错，
你把函数入口参数该为const或者把default_mode声明前面的const不要就可以编译通过了

lycreturn

强制转换一下  write_BL6523_reg(MODE, (unsigned  char *)default_mode);
