确定了Hex文件,还有三个参数项要修订,一是“CLKDIV8(Divide clock by 8)”参数项修改为“Unprogrammed”;二是“CKSEL Fuses”参数项修改为“(1111)Ext. Crystal 8.0-MHz”;三是Advanced Properties的Clock Frequency参数项设为16Mhz。最后点击编辑对话框的“确定”按钮,然后就可以仿真了,如图:(双击ATMEGA328P) ...

This function modifies the clock frequency for I2C communication. I2C slave devices have no minimum working clock frequency, however 100KHz is usually the baseline. Syntax Wire.setClock(clockFrequency) Parameters clockFrequency: the value (in Hertz) of desired communication clock. Accepted values are ...
