Time-of-Flight (ToF) Linux Reference Driver

The driver was developed on tested with the ams OSRAM TMF882X_EVM_DB_DEMO Evaluation kit. This EVM includes a Rasperry PI Zero where the Linux driver is operating.

1. Description

   Contains the release files for adding tmf882x support to the linux kernel

   /arch/arm/boot/dts Contains the device tree overlay for the TMF882X proto- typed on the Raspberry Pi zero. The rpi.env script is a convenience script for setting up build environment variables to point to a remote linux kernel source tree. This prototyped version uses GPIO_20 for INT and GPIO_16 for the "Chip-Enable" line

    -tof8820-overlay.dts
        -normal configuration, CE gpio and INT gpio
        -change the "poll_period" attribute to use polling instead of interrupts
   

2. Compiling
