I'm working on the LPC1837 micro controller. i have a query regrading the ADC conversion of the ADC0 channel 0.
ADC0 channel 0 has be connected to the port 4 and pin 3 of the micro controller. as per the data sheet , i have matched it.
Question: I'm feeding the fixed voltage of 12.5 v to the ADC 0 channel 0. but when i'm output value is varies from 0 to max and again decrease from Max to 0.
i'm facing the issue only in the channel.
where as the output for the other channel are obtain are correct.
