Page 3: Introduction
1 Introduction The CYW920819REF-KB-01 platform is designed as a Cypress HID Reference Keyboard, using the CYW920819EVB-02 Evaluation Kit connected to the keyboard hardware as described in this document. It is supported in ModusToolbox™ 2.0 with BTSDK 2.1 (or higher). It can be programmed with BR/EDR and/or LE Bluetooth applications to demonstrate a standard Bluetooth keyboard device. -

2 Hardware Setup This chapter describes setting up the hardware using the CYW9208xxEVB-02 Board (EVB) as a UART-USB adapter and power supply. HID Reference Keyboard User Guide Document Number: 002-29203 Rev. *A... -
Page 5: Power And Ground
Hardware Setup 2.1 Power and Ground Connect VDD to EVB J16-P2 where it is labeled as “3V3”. Connect GND to EVB J11-P6, GND. To make sure that the board is powered, put jumpers between EVB P2-P4 in J7 and J8 as shown below: HID Reference Keyboard User Guide Document Number: 002-29203 Rev. -
Page 6: Reset And Recovery Buttons
Hardware Setup 2.2 Reset and Recovery Buttons Shorting the BT_RST (RST_N) pin in the module to ground will reset CYW20819. Put a push button in between. While shorting CTS to ground, resetting the device will allow the device to bypass Flash boot and enter Auto Baud Recovery mode. - Page 7 Hardware Setup HID Reference Keyboard User Guide Document Number: 002-29203 Rev. *A...

Hardware Setup 2.4 Connecting PUART Remove all jumpers from EVB J10 and connect EVB P31 J10-P6 (TX). HID Reference Keyboard User Guide Document Number: 002-29203 Rev. *A... - Page 10 Hardware Setup When the EVB board is connected to a USB port on a host PC, the system will enumerate two serial ports: one for HCI UART and one for PUART. The HCI UART port is used for programing from ModusToolbox. Use a serial port terminal application to open the PUART port so that the firmware debug output can be shown.

Page 11: Programming
In ModusToolbox IDE, click on the New Application link in the Quick Panel to create a new project. Select the CYW920819REF-KB-01 platform and then select wiced_btsdk. This installs the prerequisite SDK support needed for the keyboard application. This needs to be performed only once. -
Page 12: Testing_Using_Hci Option
Programming Alternatively, after the application and wiced_btsdk have been created in the ModusToolbox IDE, the firmware can be built and downloaded using the command line. Do the following: Open a command prompt (CMD, xterm, etc.) and change directory to the ModusToolbox workspace folder (the mtw folder in the user home directory by default), and execute the following commands: $ cd HID_20819REF_KB/hid/dual_mode_keyboard $ make clean... -
Page 13: Sleep_Allowed Option
Programming 3.4 SLEEP_ALLOWED Option There are four levels of Sleep options, which are configurable in the makefile or via command line override. In makefile, change SLEEP_ALLOWED_DEFAULT=n In Cygwin command line, use SLEEP_ALLOWED=n Where n is: No sleep allowed Sleep is allowed without Deep Sleep: Radio powered down and digital core is mostly powered down except for RAM, registers, and some core logic. -
Page 14: Led Options
Programming PUART output: <<CY DUAL MODE KB start>> SLEEP_ALLOWED=2 OTA_FW_UPGRADE SKIP_PARAM_UPDATE … 3.5 LED Options The LED functionality is enabled by default. It can be disabled by changing the makefile to use LED_SUPPORT_DEFAULT=0, or via a command line override using the LED=0 parameter. The LED function should be turned off for power measurement. There are four LEDs available on the keyboard reference board: WHITE, BLUE, YELLOW, and RED. -
