Hardware Overview
How does it work?
16x12 G Click carries a 16x12 LED display and the IS31FL3733 matrix driver. The click is designed to run on either a 3.3V or 5V power supply. It communicates with the target microcontroller over the I2C interface and the following pins on the mikroBUS™ line: INT, RST, and CS. Each LED can be controlled individually for on/off control
and light intensity. The IS31FL3733 is a general purpose 12×16 LED matrix driver with a 1/12 cycle rate. Each of the 192 LEDs can be dimmed individually with 8-bit PWM data, which allows 256 steps of linear dimming. The driver has selectable 3 Auto Breath Modes for each LED ( ABM-1, ABM-2, and ABM-3). This Click board™ can operate with
either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
Nucleo 32 with STM32F031K6 MCU board provides an affordable and flexible platform for experimenting with STM32 microcontrollers in 32-pin packages. Featuring Arduino™ Nano connectivity, it allows easy expansion with specialized shields, while being mbed-enabled for seamless integration with online resources. The
board includes an on-board ST-LINK/V2-1 debugger/programmer, supporting USB reenumeration with three interfaces: Virtual Com port, mass storage, and debug port. It offers a flexible power supply through either USB VBUS or an external source. Additionally, it includes three LEDs (LD1 for USB communication, LD2 for power,
and LD3 as a user LED) and a reset push button. The STM32 Nucleo-32 board is supported by various Integrated Development Environments (IDEs) such as IAR™, Keil®, and GCC-based IDEs like AC6 SW4STM32, making it a versatile tool for developers.
