We want to call theSPI.transfer()function, sending theAMT22_NOPcommand. We will leave CS low. The high byte comes first, so in a single line of code we will call the function, shift it left 8 bits to get that first byte (8 bits) into the top half of the uint16_t variable, an...

To open the example sketches click on “File->Examples", find the "Epson SU SPI...", and then select one of the example sketches. Once the example sketch is loaded, it can be compiled and uploaded to the Arduino. Note that the Upload stage will fail if the Sketch “Board” and “...
IO12(GPIO12)、IO13(GPIO13)在QIO模式下为SPI信号SPIHD和SPIWP复用,为了增加可用GPIO数量,开发板选择采用2线SPI的DIO模式,IO12、IO13并未连接flash,使用自己编译的软件时需要注意配置flash为DIO模式。 外置SPI flash的VDD已链接至3.3V电源系统,使用时不需再配置其他电源,采用普通2线SPI通信方式。
