This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory.
最后，将clock引脚置为高电平以储存全部数据，并立即置为低电平以禁止进一步的数据传输。最后，将latch引脚置为高电平，以并行方式送出所有已传输的数据。2. 实验所需材料 Uno R3开发板USB数据线面包板及连接线74HC595芯片220Ω限流电阻8个LED发光二极管8个 3. 实验步骤 搭建电路，依据原理图进行连接。将8个LED发光...
