Page 15: Microtouch™ Ex Usb Controller Communications
3M™ MicroTouch™ EX USB Controller Communications This chapter discusses the fundamentals of communicating with the 3M™ MicroTouch™ EX USB controller. The firmware commands, which are usually issued by a driver or utility program on the host system, control the operation of the touch controller, however developers can enter these commands directly. -
Page 16: Communicating With The Controller
You should be aware of the results before executing any firmware commands. To optimize the performance of the 3M™ MicroTouch™ EX USB touch controller and simplify the development of custom drivers, 3M Touch Systems recommends you use the commands listed in this chapter for current development. Using these commands ensures compatibility with all 3M™... -
