PIC16F系列MCU用printf函数调试程序时能否打印浮点类型，如果能需要怎样配置？
例如 printf("a = %f\r\n",a); a是浮点型，当是%f编译就会出错，改为%d就能正常编译，
报错信息：:0:: error: (1347) can't find 0x22F words (0x22f withtotal) for psect "text20" in class "CODE" (largest unused contiguous range 0x208)
Non line specific message::: advisory: (1493) updated 32-bit floating-point routines might trigger "can't find space" messages appearing after updating to this release; consider using the smaller 24-bit floating-point types |
