【arduino】请教买了3.5寸的tft屏，烧示例程序时出现下面的错误

CTE_35inch_480x320.ino:27:17: error: SPI.h: No such file or directory
CTE_35inch_480x320.ino: In function 'void setup()':
CTE_35inch_480x320:55: error: 'SPI' was not declared in this scope
CTE_35inch_480x320:56: error: 'SPI_CLOCK_DIV2' was not declared in this scope
tools已经里面选择了对应的板和串口
请问这是什么原因呢
