Quick start guide for touch-screen controllers

This application note demonstrates how to quickly develop code for the MAX11800–MAX11803 and MAX11811 resistive touch-screen controllers and operate them in direct or autonomous mode. Software is provided to help compute data conversion based on the register settings.

The MAX11800–MAX11803 and MAX11811 touch-screen controllers can quickly be made operational in either direct or autonomous mode. This application note breaks down the procedure of communication into two steps. First, users must set all the configuration registers. The second step requires sending a set of commands that produces the desired data (X, Y, Z1, Z2).
