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.

„ Operation procedure
1. Wiring of a power supply
VCC (Red) =2.5V∼3.6V
AGND (Black) = 0V
DGND (Black) = 0V
IFVDD (Orange) = VCC
JP1-short (default: CAD0pin = “L”), JP2-short
2. A setup of I2C address J1 (short: CAD0pin =”L“, open: CAD0pin = ”H“)
3. Connect I2C I/F (SCL, SDA) to uP.
4. A setup of evaluation mode, jumper
5. Power supply ON
6. Run the control soft
„ Evaluation mode selection
1) Position, Pen Pressure
4 wire touch-panel (X+, X-, Y+, and Y-) is connected to J1 connector.
Jumper setup
JP3 (XPSEL) ---------select XP
JP4 (YPSEL) ---------select YP
JP5 (XNSEL) ---------select XN
JP6 (YNSEL) ---------select YN
„ Power supply injection, Evaluation
1) Digital serial data input
When the control command data indicated by specification from digital I/F (P1 or PORT1) was inputted the AD
conversion is carried out and is outputted from a SDA.
„ 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.

„ 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.

„ 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.
