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
