Featrues

• 1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
• 2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.

Specifications

Note 1: S for digital output port, V and G for voltage at the common collector and ground respectively. Generally speaking, digital output is VCC; when the button is pressed down, the digital output is 0V.

How to port

This demo is based on CoX M051 library, if you want to port to other CoX library, Just do the simple step below.
The Tilt driver is commucate with GPIO pin, so in the CooperKit_Hall.h file, the port configuration group provides the gpio pin connection Macro to user for port. For example your Hall signal pin is connect to GPIOA PIN2, you should modify the Macro as:

//*****************************************************************************
//
//! \addtogroup CooperKit_Hall_Config
//! CooperKit Hall configurator
//! @{
//
//*****************************************************************************

//
//! Configure the pin connection of CooperKit Hall
//
#define CooperKit_Hall_PIN         PA2

//*****************************************************************************
//
//! @}
//
