Question

warning: #167-D: argument of type "u8 *" is incompatible with parameter of type "char *restrict"

出问题的是这行：sprintf(s,"%02.0f",(float)Sensor_Box.ad7730_1);
看了下sprintf函数的原型是：
int sprintf( char *buffer, const char *format [, argument] … );
请问该怎么修改实参，使其与形参类型一致？

Answer 1

把s类型由(u8* 也可能是 unsinged char*)改成char*
或者简单的改成sprintf((char*)s,"%02.0f",(float)Sensor_Box.ad7730_1);
