[ASAHI KASEI] [AKD4183] AKD4183 AK4183 Rev.A Evaluation Board Abstract AKD4183 is the board for evaluation of the touch screen controller AK4183 which adopted the TMSOP small package suitable for the cellular phone, the handheld game machine, etc. Since AKD4183 has a touch-panel I/F and a digital I/O power supply input terminal, it is easily connectable with a target system of low power/voltage drive.

Parallel Port Driver install Attached software is the application software which checks the function of the AK4183. Windows(R) Win98, Win2K, and WinXP are supported. However, to make it operate on Win2K and XP, it is necessary to install driver in advance. Please follow a procedure with reference to DriverSetupe.pdf. Installation of a driver is unnecessary to use it by the Windows 98 system. <KM085700> 2006/9 -1- [ASAHI KASEI] [AKD4183] Run the software (AK4183_070.exe) First match Port Address of your PC environment. Measurements are started when the start button is clicked after select Channel Selection, MODE, and Power Down 0. A result will be displayed on AD OUT Section. When carrying out position detection, the position where pen clicked on the touch panel is measured. Operation can set up two control commands. Continuation operation can be performed. Each data (mean, max, and min) is also displayed at the same time. PENIRQN can be seen by the break of a command. <KM085700> 2006/9 -2- [ASAHI KASEI] [AKD4183] Trouble Shooting 1. Application error is occurred and doesn’t start up If the operating system is Window2000/X, Please install AKMport driver in advance of run the AK4183_070.exe. 2. MEAN value in AD OUT section does not change when click start button (cannot write control command to AK4183) Please set the port address to your PC platform environment. 3. The mean, max, min value doesn't change wherever the pen pushes down on the panel. There is a possibility of the trouble of the contact of the relay connector (plat 8pin-8-wire female dip converter) that connects the touch panel. Please open JP3, 4, 5, and 6 on the evaluation board, measure panel seat resistance (XP-XN, YP-YN), and check the resistance. Generally, the panel seat resistance is hundreds of Ω. There is a possibility that the touch panel is not correctly connected if the resistance is over thousands of kΩ. Please connect the relay connector and check the resistance value again. <KM085700> 2006/9 -3- [ASAHI KASEI] [AKD4183] Revision History Date (YY/MM/DD) 06/09/22 Manual Revision KM085700 Board Revision 0 Reason Contents First edition IMPORTANT NOTICE • These products and their specifications are subject to change without notice.
