Adafruit STMPE610 + ILI9341 touch not working

I cannot find much information on this older module.

The TFT works great with the enhanced ILI9341 library

I hooked the touch CS to pin 8 of the Teensy 3.2 as the touchpaint example explained to do. The board hangs after the 'touch chip not found message'.

Is pin 26 the correct pin for TP_CS on the Adafruit module?

Or is this module actually an I2C chip? The chip has 811CN435 on it.

Is the TP_IRQ required? The example says it is optional...perhaps the irq line need a pullup or pulldown?

TIA
