MIKROE TMPM4K Clicker 4 Development Kits
Introduction
Clicker 4 for TMPM4K is a compact development board designed as a complete solution, you can use it to quickly build your own gadgets with unique functionalities. Featuring a TMPM4KNFYAFG MCU, four mikroBUS sockets for Click boards connectivity, power management, and more, it represents a perfect solution for the rapid development of many different types of applications. At its core, there is a TMPM4KNFYAFG MCU, a powerful micro controller by Toshiba, based on the high-performance Arm® Cortex®-M4 32-bit processor core operating at up to 160 MHz frequency. It provides sufficient processing power for the most demanding tasks, allowing Clicker 4 to adapt to any specific application requirements.Besides two 1×20 pin headers, four improved mikroBUS sockets represent the most distinctive connectivity feature, allowing access to a huge base of Click boards , growing on a daily basis. Each section of Clicker 4 is clearly marked, offering an intuitive and clean interface. This makes working with the development board much simpler and thus, faster. The usability of Clicker 4 doesn’t end with its ability to accelerate the prototyping and application development stages: it is designed as a complete solution which can be implemented directly into any project, with no additional hardware modifications required. Four mounting holes [4.2mm/0.165”] at all four corners allow simple installation by using mounting screws. For most applications, a nice stylish casing is all that is needed to turn the Clicker 4 development board into a fully functional, custom design.
Key Microcontroller Features
At its core, Clicker 4 for TMPM4K uses the TMPM4KNFYAFG MCU.
TMPM4KNFYAFG is the 32-bit ARM® Cortex®-M4 core. This MCU is produced by Toshiba, featuring a dedicated floating point unit (FPU), memory protection unit (MPU), and advanced features ideal for motors and industrial equipment applications. Among many peripherals available on the host MCU, key features include:
- 256kB Code Flash
- 32kB Data Flash
- 24kB of SRAM
- Operating frequency up to 160 MHz
- Advanced programmable motor control circuit (A-PMD)
- Advanced vector engine plus (A-VE+)
- Advanced Encoder input circuit (32-bit) (A-ENC32)
For the complete list of MCU features, please refer to the TMPM4KNFYAFG datasheet.
MCU Programming
Programming with on-board debug unit
- Clicker 4 for TMPM4K uses Toshiba’s TMPM067FWQG as the on-board Debug Unit. It is compliant with an on-board emulator standard called CMSIS-DAP.
- CMSIS-DAP is the interface firmware for a Debug Unit that connects the Debug Port to USB. Debuggers, which execute on a host computer, connect via USB to the Debug Unit and to the Device that runs the application software. The Debug Unit connects via JTAG or SW to the target Device. Once Clicker 4 is powered up, and PWR/DBG connector is connected to the PC, it takes a few seconds for the on-board Debug Unit to initialize. After the on-board CMSIS-DAP is initialized, two LEDs RUN and COM blink one time.
Programming with an external programmer
The microcontroller can be programmed with an external programmer and supported software. The external programmer is connected to the development board via a 2×5 JTAG/SWD connector soldered on the J2 connector pads.
Note: Before usage, please check if the programmer pinout and the 2 x 5 pin header pinout are compatible. Based on the used programmer/debugger tool pinout, a corresponding adapter might be needed.
MCU reset
- Clicker 4 for TMPM4K development board is equipped with the reset button labeled as RST (1), located on the front of the board. It is used to generate a LOW logic level on the MCU reset pin.
- The RST pin of the host MCU is also routed to the pin 40 of the 1 x 20 pin header (2), allowing an external signal to reset the MCU.
Buttons and LEDs
- The board also contains six buttons and LEDs, located on the front side. Buttons (1) can be used to apply the desired logic state to pins of the MCU they are routed to. Pressing any of the six buttons can change the logic state of the microcontroller pins from logic high (1) to logic low (0).
- CLICKER 4 for TMPM4K U S E R M A N U A L LEDs (2) can be used to visually indicate a logic state of the specific pin. The maximum current through a single LED is limited with the 4.7k resistor. Each LED is connected to a MCU pin, and an active LED indicates that a logic high (1) is present.
Power Supply
After a valid power supply source is connected (1 – 2 – 3 – 4), Clicker 4 for TMPM4K can be powered ON. A LED indicator labeled as PWR (5) indicates that the board is powered ON.The power supply unit (PSU) provides clean and regulated power, necessary for proper operation of the Clicker 4 for TMPM4K development board. It is equipped with four different power supply inputs, offering all the flexibility that Clicker 4 for TMPM4K needs, and a reliable and safe battery charging circuit, which allows a single-cell Li-Po/Li-Ion battery to be charged.As explained, the advanced design of the PSU allows four types of power sources to be used, offering unprecedented flexibility: when powered by a Li-Po/Li-ION battery, it offers an ultimate degree of autonomy. Power is not an issue even if it is powered over the USB cable. It can be powered over the USB-C connector, using power supply delivered by the USB HOST (i.e. personal computer), USB wall adapter, or a battery power bank. There are five power supply connectors available, each with its unique purpose:
- CN1, CN2: USB-C connector (1)
- J1: Standard 2.5mm pitch XH battery connector (2)
- TB1, TB2: A place for a standard 2.54mm terminal block (3,4)
Connectivity
Clicker 4 offers a variety of connectivity options including USB-UART, four standardized mikroBUS™ sockets, and two 1×20 pin headers which are used to directly access the host MCU pins. Clicker 4 supports USB to serial UART interface, allowing the development of a wide range of various USB-based applications.
A lot of the host MCU pins are routed to two 1×20 pin
headers, making them available for further connectivity. In addition to MCU
pins, some additional peripheral pins are also routed to this header.
Click boards
