基础板是Arduino UNO Ver3 Board,Ethernet Shield作为SD和WebServer扩展板,vs1003作为解码器,端口A0-A4用作数字IO模拟SPI来驱动VS1003。 以前用PIC32做了一个月才做出来,今天用Arduino UNO一天就能够给弄出来了。 不过Arduino UNO的芯片Atmega 328最多最多跑到20MHZ,数组申请过了512都hold不住(BootLoader和Text一...
the SI4732-A10 provides the same address when the SEN pin is connected to the +VCC. Also, this library provides the functiongetDeviceI2CAddressto detect the I²C bus address automatically. This way, you don't need to worry about this setup if you use this function. SeegetDeviceI2CAddres...
我已经掌握了使用ArduinoIDE的基本功能,但是我决定想要一个更强大的编辑器,所以我转而使用Visual代码。它工作良好,草图打开,编译,并上传到董事会,没有任何问题。(奇怪的是,对于D7在pins_arduino.h中的定义,它也将uint8_t标记为未定义, 浏览5提问于2020-02-29得票数4...
