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.
• 3. With separation circuit to prevent damages to I / O port.

Specifications

Note 1: S for digital output port, V and G for voltage at the common collector and ground respectively.

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 Buzzer is commucate with GPIO pin, so in the CooperKit_Buzzer.h file, the port configuration group provides the gpio pin connection Macro to user for port. For example your Button signal pin is connect to GPIOA PIN2, you should modify the Macro as:

//*****************************************************************************
//
//! \addtogroup CooperKit_Buzzer_Config
//! CooperKit Buzzer configurator
//! @{
//
//*****************************************************************************
//
//! Configure the pin connection of CooperKit Buzzer
//
#define CooperKit_Buzzer_PIN     PA2

//
//! Set the effective output level of CooperKit Buzzer to sound
//
#define CooperKit_Buzzer_EFFECTIVE_LEVEL                   \
                         0
//*****************************************************************************
