Hello, I am using a MCB1700 with LPC1768 currently. After downloading the blinky code and disabling the potentiometer by removing the jumper AD0.2 and after giving my analog input from my measurement system to pin P0.25, the adc output displayed on the LCD display(hexadecimal and bar graph output) is fluctuating over a considerably wide range.The same works without any fluctuations when the analog input for potentiometer is given by connecting the jumper at ADO.2.
So,my query is how to interface my multiple analog inputs to this board without much fluctuations in measurement and eliminating the external noises.
Thanks.
