hai everyone….I am learning embedded C programming using 8051. i am interested in doing a project on Resistive Touch Screen interface to 8051 to control the dc motor. Can anyone give some suggestions?

I suggest you to use a microcontroller with in-built ADC like ATMega16, since 8051 has no ADC. you can get the code for it here only

resistive touch screen have 4 wire interface and it gives analog output. so you need to have ADC with mux to interface it with 89C51
