April 13, 2014 at 6:02 am #11541
I have written a code such that the o/p values of touch screen are converted to digital values and transmitted through UART so that I can easily note down the touch screen digital values of x-y coordinates . When monitoring the digital values of ADC keeps varying a lot!!! Please help.. Any suggestions?
I have connected the pins of touchscreen directly to my controller. Is there any necessity of any external circuit?
Thanks in advance.
