Figure 25 illustrates the default jumper positions as mounted when the board is delivered from

Embedded Artists. Default jumpers are marked with red color.

Figure 25 – OEM Base Board Default Jumper Positions

Note that the default position for the six I2S jumpers is not what is needed for the LPC3250

OEM board. Also, JP34 is in wrong position. Before working with I2S audio and the LCD

interface change the jumper settings. Jumpers needed to change are marked with green – this

is the position they should have.

Some signals are used on different interfaces that cannot be active simultaneous. See table in next

section for information about pin usage.

to pos 2-3

Change JP22, JP23, JP24, JP25,
