自制完全成功!!!!ADC0809时钟直接使用AT89C51的ALE信号2MHz P1口段码,P2.0-3位码(P2.0为最右边数码管的位码)

P0口数据输入 通道0输入,ADC0809中ST和ALE---P3.0,EOC---P3.2,CLK---ALE.OE---P3.1*/-made entirely successful! ! Connection between ADC 0809 clock direct access to the ALE signal AT89C51 2MHz P1 mouth of the code, P2.0-3-bit code (P2.0 most of the right side of the digital-code) P0 export data input channel 0 input, Connection between ADC 0809 ST and China --- P3.0 ALE, the EOC --- P3.2. CLK --- --- ALE.OE P3.1 * /
