STEPS FOR ASSEMBLING S5U13781R00C10M DEVELOPMENT PACKAGE
Modification to Stellaris LM4F120 Launchpad Board
1)
On the Stellaris LM4F120 Launchpad board, remove (de-solder) resistors R9 and R10. This
disconnects the short-circuits between GPIO ports PB6/PD0 and PB7/PD1.
Soldering of Header and Receptacles
2)
On the S5U13781R00C100 Main Board, connect pins 3 and 4 of J3 (solder a wire across the two
pins or solder a header with shunt jumper) to set the current of the backlight LED driver to 20mA.
The Newhaven 3.5” display is rated at 20mA typical and the Newhaven 4.3” display is rated at
32mA typical. (Current drive can be increased in steps of 20mA by shorting pins 5-6 and pins 7-
8 of J3.)
3)
On the S5U13781R00C100 Main Board, connect pins 1 and 2 of J1 (solder a wire across the two
pins or solder a header with shunt jumper) to connect power for the Serial Flash.
4)
On the bottom side of the
S5U13781R00C100 Main Board
, install and solder 2x25 headers for
J4 and J5.
5)
On the top side of the
S5U13781M00C100 Board A
, install and solder 2x25 receptacles for P5
and P9.
6)
On the bottom side of the
S5U13781M00C100 Board A
, install and solder 2x10 receptacles for
P1+P3 and P2+P4. (Note that P1 and P3 together make up one 2x10 receptacle and P2 and P4
together make up the other 2x10 receptacle.)
7)
On the bottom side of the
S5U13781M00C100 Board A
, install and solder a 2x25 header for J2.
8)
For a 40-pin (4.3”, WQVGA) LCD module, use
S5U13781M00C100 Board B
and install (on the
top side) 2x25 receptacles for PB1 and PB2. For a 54-pin (3.5”, QVGA) LCD module, use
S5U13781M00C100 Board C
and install (on the top side) 2x25 receptacles for PC1 and PC2 as
well as a 2x3 receptacle for PC3.
9)
On the bottom side of the
S5U13781R00C100 LCD Interface Board
, install and solder a 2x25
header for J9. If using a 54-pin LCD module, a 2x3 header for J10 should also be installed and
soldered on the bottom side of the
S5U13781R00C100 LCD Interface Board
.
