Overview

This is the 2/3 chapter of IGEP PARIS Expansion Tutorial Guide.

We will learn some basic tasks.



What can I do

You must logged in the board.

How to use TFT and Touchscreen

200px
IGEP PARIS Expansion supports SEIKO 7” LCD screen. Use J200, J203 and J204 connectors to attach screen. See image for more details.

By default, Seiko screen is supported in IGEP PARIS. However open igep.ini, you can do this checking following kernel cmdline parameter: 

omapdss.def_disp=lcd-70


How to use EEPROM

IGEP PARIS Expansion includes a serial EEPROM, provides 1KB of user data storage. EEPROM is connected through I2C2 of OMAP3 processor at address 0x50.

The following example writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 3: 

$ i2cset -f -y 3 0x51 0x10 0x22
$ i2cget -f -y 3 0x51 0x10

How to use serial console

Paris db9.jpg
Connect a DB9 cable between IGEP PARIS and Host PC. Open the serial on your PC using your preferred serial communications program (minicom) and configure the port as follows:
  • 115200
  • 8N1
  • no flow control (either software or hardware)

Open the serial port and the debug shell prompt should appear.

A detailed guide on how to connect via serial debug port can be found by following this link: Using serial debug port to communicate

How to use SW101 button

IGEP PARIS has a button configured like GPIO. You can test it using the following program: 

$ evtest /dev/input/event0

Now press the button and see program traces.


You have successfully completed this chapter of the guide.
