KL25Z TSI (touch sensor interface) pin name to channel mapping

Page last updated 03 Aug 2014, by Bjoern Hartmann. 0 replies

The TSI library used in the KL25Z code template in the online IDE uses channel names instead of pin names to configure the touch sensor. Here is a correspondence table between pin names and channel numbers taken from the data sheet at http://cache.freescale.com/files/32bit/doc/data_sheet/KL25P80M48SF0.pdf?fasp=1

  • PTA0 - TSI0_CH1
  • PTA1 - TSI0_CH2
  • PTA2 - TSI0_CH3
  • PTA3 - TSI0_CH4
  • PTA4 - TSI0_CH5
  • PTB0 - TSI0_CH0
  • PTB1 - TSI0_CH6
  • PTB2 - TSI0_CH7
  • PTB3 - TSI0_CH8
  • PTB16 - TSI0_CH9
  • PTB17 - TSI0_CH10
  • PTB18 - TSI0_CH11
  • PTB19 - TSI0_CH12
  • PTC0 - TSI0_CH13
  • PTC1 - TSI0_CH14
  • PTC2 - TSI0_CH15
