HAM Main Controller:
Description:
The HAM CUBE multi-function controller is an ARM-based embedded HAM product. The main purpose is to build an open architecture that can be used to achieve some HAM daily commonly used functions. It can also complete certain core functions when used alone.

The firmware of "HAM CUBE Multifunctional Controller" that can be used independently is CW trainer firmware (hereinafter referred to as CW trainer). The firmware has the most basic functions of CW listening, transcription, and reporting exercises, which can effectively help CW beginners learn and improve CW's ability to send and receive reports. At the same time, it also has the function of controlling the radio to send CW through the external interface; it has the function of adaptive speed real-time decoding by the opponent key and automatic key code. In the future, the radio interface expansion board will have the ability to adaptively demodulate external CW signals.

The core of the CW trainer is a 32-bit ARM-STM32F103CBT6. The chip has 128k of FLASH space and 20k of RAM space, and the working frequency is 72M. A 1.8-inch 160*128 resolution is installed on the front of the main control board. 16-bit true color TFT-LCD liquid crystal display, as the display device of the main controller. The board is designed with 4 touch buttons, a three-way toggle switch, a system hardware reset button and a power supply repair pad jumper; There are 2 user-programmable LED indicators (D2, D3); the external function interface with up to 24 pins leads out as many MCU pins as possible for external use and function expansion; the reset button is located on the lower left of the front of the device Angle, the main control board can be reset by hardware by pressing the fine needle; the 6P programming interface can be used to connect professional embedded development equipment, and carry out secondary development and programming of the internal MCU.

Features:
As a master:
1. The appearance is small and exquisite, real palm-sized device
2. Integrated 1.8-inch true color TFT LCD screen and user function buttons
3. Abundant on-board resources and external interfaces
4. Function expansion board can be added flexibly to realize other functions
5. Various system functions can be realized by writing different system support firmware

After Entering CW Trainer System Supported Firmware:
1. It can realize self-practice function that runs through all aspects of CW training
2. Abundant transcription training modes with letters, numbers, mixes, call signs, phrases, and custom characters
3. It can be used as a CW key controller, controlling an external shortwave radio station to transmit CW signals
4. With 4pcs custom shortcut keys, you can easily program CW common communication phrases
5. Used with CW decoding expansion board, it can decode external CW audio signal in real time, and the main controller screen displays
