Released:

A CircuitPython driver for Cirque Pinnacle (1CA027) touch controller used in Cirque Trackpads implementing the Adafruit_BusDevice library.

Project description

Introduction

A CircuitPython driver library that implements the Adafruit_BusDevice libraryfor interfacing with the Cirque Pinnacle (1CA027) touch controller used in Cirque Circle Trackpads.

Supported Features

• Use SPI or I2C bus protocols to interface with the Pinnacle touch controller ASIC (ApplicationSpecific Integrated Circuit).
• Relative mode data reporting (AKA Mouse mode) with optional tap detection.
• Absolute mode data reporting (x, y, & z axis positions).
• AnyMeas mode data reporting. This mode exposes the ADC (Analog to Digital Converter) values and isnot well documented in the numerous datasheets provided by the Cirque corporation about thePinnacle (1CA027), thus this is a rather experimental mode.
• Hardware input buttons’ states included in data reports. There are 3 button input lines onthe Cirque circle trackpads – see Pinout section.
• Configure measurements for finger or stylus (or automatically detirmine either) touchevents. The Cirque circle trackpads are natively capable of measuring only 1 touchpoint per event.
• Download/upload the underlying compensation matrix for ADC measurements.
• Adjust the ADC matrix gain (sensitivity).

Tip

The SPI protocol is the preferred method for interfacing with more than 1 Cirque circletrackpad from the same MCU (microcontroller). The Cirque Pinnacle does not allowchanging the I2C slave device address (via software); this means only 1 Cirque circle trackpadcan be accessed over the I2C bus in the lifecycle of an application. That said, you could changethe I2C address from 0x2A to 0x2C by soldering a 470K ohm resistor at the junctionlabeled “ADR” (see picture in Pinout section), although this is untested.

Unsupported Features

• The legacy PS2 interface is pretty limited and not accessible by some CircuitPython MCUs.Therefore, it has been neglected in this library.
• Cirque’s circle trackpads ship with the newer non-AG (Advanced Gestures) variant of thePinnacle touch controller ASIC. Thus, this library focuses on the the non-AG variant’sfunctionality via testing, and it does not provide access to the older AG variant’s features(register addresses slightly differ which breaks compatibility).

Pinout

The above picture is an example of the Cirque GlidePoint circle trackpad. This pictureis chosen as the test pads (larger copper circular pads) are clearly labeled. The test padsare extended to the 12-pin FFC/FPC cable connector (the white block near thebottom). The following table shows how the pins are connected in the examples (tested on an ItsyBitys M4)

Tip

Of course, you can capture button data manually (if your application utilizes morethan 3 buttons), but if you connect the pins B1, B2, B3 to momentary push buttons that(when pressed) provide a path to ground, the Pinnacle touch controller will report all 3buttons’ states for each touch (or even button only) events.
