We want to call the SPI.transfer() function, sending the AMT22_NOP command. 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 variabl...
5. UNOArduSim: The Lightweight Code Tester UNOArduSim, created by Canadian professor Dr. Sven Bilén in the early 2010s, is the minimalist’s choice among the best Arduino simulators. This open-source desktop tool focuses narrowly on Arduino Uno code execution, stripping away circuit visuals f...

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。 GPIO11默认为S...
The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...

当你在那里,也寻找Adafruit_SPIFlash库并安装它类似。 还需要一个库,但是不能通过库管理器安装它。SdFat库的Adafruit分支需要以. zip文件的形式下载,解压缩后用Arduino老的安装库方式安装。 链接:pan.baidu.com/s/1e0F_if 提取码:l6o1 使用Adafruit_ImageReader库 使用这个库(以及上面的独立安装)的语法确实有...
