Microcontroller › 8051 › random ADC0808 output values. › i already check your example

i already check your example codes…

 

 

same here.. i notice that if the input value of ADC in each channel is less that 4v the value is correct and then if more between 4v and 5v the value is in random…

 

i want someone who could explain that to us why is the weird thing happening when we use ADC0808..

 

weeks later i made a project using adc0804 but it is working fine but when i use adc0808 im stuck because of that random values..

 

i tried many example code from defferent forums but all the results are the same.. always random values..
