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...
** CS - depends on your SD card shield or module. Pin 4 used here for consistency with other Arduino examples created 28 Mar 2011 by Limor Fried modified 9 Apr 2012 by Tom Igoe */ // include the SD library: #include <SPI.h> #include <SD.h> // set up variables using the SD ut...
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...
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...
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. ...
