CYW920829-MOUSE BSP

Overview

The AIROC™ CYW20829 mouse reference solution is an ultra-low power mouse design with multi-host support that demonstrates Bluetooth® LE HID over GATT profile It comes with the right combination of low power and high performance dual core Arm® Cortex® M33 to meet the demands of battery powered mouse.

To use code from the BSP, simply include a reference to cybsp.h.

Features

Kit Features:

  • 32-bit CPU subsystem with Arm® Cortex® M33
  • 256-KB SRAM with power and data retention control
  • Low power 2.1 - 3.0 V operation
  • Bluetooth® LE 5.4 core spec-compliant
  • Battery voltage measurement with 16 bit ADC
  • 5-pin SWD connectors
  • Left, Right, Middle and DPI buttons
  • SPI based optical motion sensor
  • F-switch Quadrature Encoder for scroll wheel

BSP Configuration

The BSP has a few hooks that allow its behavior to be configured. Some of these items are enabled by default while others must be explicitly enabled. Items enabled by default are specified in the CYW920829-MOUSE.mk file. The items that are enabled can be changed by creating a custom BSP or by editing the application makefile.

Components:

  • Device specific category reference (e.g.: CAT1) - This component, enabled by default, pulls in any device specific code for this board.

Defines:

  • CYBSP_WIFI_CAPABLE - This define, disabled by default, causes the BSP to initialize the interface to an onboard wireless chip if it has one.
  • CY_USING_HAL - This define, enabled by default, specifies that the HAL is intended to be used by the application. This will cause the BSP to include the applicable header file and to initialize the system level drivers.
  • CYBSP_CUSTOM_SYSCLK_PM_CALLBACK - This define, disabled by default, causes the BSP to skip registering its default SysClk Power Management callback, if any, and instead to invoke the application-defined function cybsp_register_custom_sysclk_pm_callback to register an application-specific callback.

Clock Configuration

Clock Source Output Frequency
CLK_HF0 CLK_PATH0 48 MHz
CLK_HF1 CLK_PATH0 48 MHz
CLK_HF2 CLK_PATH2 48 MHz
CLK_HF3 CLK_PATH0 24 MHz

Power Configuration

  • System Active Power Mode: ULP
  • System Idle Power Mode: Deep Sleep
  • VDDA Voltage: 3300 mV
  • VDDD Voltage: 3300 mV

See the BSP Setttings for additional board specific configuration settings.

API Reference Manual

The CYW920829-MOUSE Board Support Package provides a set of APIs to configure, initialize and use the board resources.

See the BSP API Reference Manual for the complete list of the provided interfaces.
