FAQ
I have an application where an ADuC831 is being used to sample a frequency input on Pin 1 (T2) input, and the rest of ADC pins are being used to sample analog voltages.
I noticed that when the timer input is exactly 8Khz, the remaining analog inputs…
用 ADUC831进行AD采样,定时器0定时50ms,每定时20次,也就是1S数码管显示一个采样值,同样的程序在STC89C52可以实现,在ADUC831就不可以,什么原因呢?将AD采样程序注释掉,单独利用定时中断控制数码管和LED灯又可以实现,放在一起就不可以~
