Touch Sensing Software
1
Install a TWRPI
Touch Module
• Identify an open touch sense or touch
pad TWRPI socket on a compatible
Tower controller module. Touch sense
sockets consist of two parallel shielded
male connectors. Touch pad sockets
consist of a single shielded male
connector.
• Carefully insert the TWRPI module into
the appropriate TWRPI socket. The
TWRPI module and socket are keyed to
only fit in the correct socket type in the
proper orientation.
• Check
freescale.com/touchsensing
and the appropriate page for the
Tower controller module on
freescale.com/Tower
for the latest
software for the TWRPI touch modules.
