Problem with an interrupt signal only affects how you will know that a conversion is done - it does not affect your ability to talk with the ADC.
"Problem with an interrupt signal only affects how you will know that a conversion is done - it does not affect your ability to talk with the ADC"
i understand this thing.My mean:i use button to allow operate ADC,star convert,,then wait signal INTR from ADC send to CHIp to alert "finish start convert",after chip will read ADC then show in leg7seg...is this right??
my code use for operating ADC
if(button1==1){ CS_1=0; WR_1=0; WR_1=1; while (INTR_1==1);//wait for signal INRT_1...cho den khi co tin hieu ngat tu ADC CS_1=0; RD_1=0; //CS_1=1 not write here khong the dat o day...dan toi ko doc duoc }
