hi sir iam using 89c51 with C51 compiler i want display voltage on & four 7segment leds.I converted anlog voltage to digital using ADC.now i want display voltage on & 7-segment leds like 0.001v 0.002v . . . 5.000v iam using only one port P1 conacted to the 7-segmentLEDs and i conacted 4 transisters to the port-P2 like P2.1 p2.2 p2.3 p2.4. how to selact the transister according to voltage pleace give one C program on this logic Thanks. chandu
"thank u for u r reply" Unless you have some physical disability that impairs your use of the keyboard, please make the effort to type "you", "your", etc, in full.
sorry sir you are saying that we have to put continous loop for display if i change input voltage then what happends to the display value. regards nari
"if i change input voltage then what happends to the display value." Surely, you want the displayed value to change?! So, each time you update a digit, be sure to write the current value for that digit!
