Hardware Overview
How does it work?
IPD Click - 2017 is based on the TPD2017FN, an 8-channel low-side switch featuring MOSFET outputs from Toshiba Semiconductor, designed to be directly driven by CMOS and TTL logic circuitry. It's ideally suited for driving inductive and resistive loads, such as industrial programmable logic controllers for industrial use, motors, relays, lamps in factory automation equipment, and more. A key advantage of the TPD2017FN is its built-in overcurrent and overtemperature protection, enhancing system stability by safeguarding against excessive heat and current. Equipped with the capability to handle back electromotive force from inductive loads without surpassing the component's voltage tolerance, the TPD2017FN is optimized for loads up to 50mH with a current capacity of 0.5A per channel, supported by an external power supply ranging from 8-24V. The channels can be
operated in parallel to increase the current capability of the outputs. As mentioned, this Click board™ incorporates comprehensive protection mechanisms, including overtemperature protection that deactivates all outputs (OUT1-OUT8) if the temperature exceeds 175°C and overcurrent protection that limits voltage and current during load shorts, ensuring the device and its connected peripheral safety. Designed for straightforward integration with CMOS and TTL systems, the IPD Click features input control terminals for each output channel, allowing independent channel control. Inputs IN1 to IN4 interface directly via the mikroBUS™ socket, with additional inputs IN5 to IN8 accessible through an unpopulated header. Each input control pin of the TPD2017FN is equipped with a built-in 300kΩ pull-down resistor to maintain a LOW logic state in an open state. This
Click board™ comes with optional inductive load decoupling diodes unpopulated by default, the CRS20140A from Toshiba Semiconductor, allowing users to add them in the case of higher inductive loads. Also, it is equipped with jumpers for the diode configuration of the used load switch and its power management. These jumpers are pre-configured, enabling immediate use without the need for any adjustments. 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
Arduino UNO is a versatile microcontroller board built around the ATmega328P chip. It offers extensive connectivity options for various projects, featuring 14 digital input/output pins, six of which are PWM-capable, along with six analog inputs. Its core components include a 16MHz ceramic resonator, a USB connection, a power jack, an
ICSP header, and a reset button, providing everything necessary to power and program the board. The Uno is ready to go, whether connected to a computer via USB or powered by an AC-to-DC adapter or battery. As the first USB Arduino board, it serves as the benchmark for the Arduino platform, with "Uno" symbolizing its status as the
first in a series. This name choice, meaning "one" in Italian, commemorates the launch of Arduino Software (IDE) 1.0. Initially introduced alongside version 1.0 of the Arduino Software (IDE), the Uno has since become the foundational model for subsequent Arduino releases, embodying the platform's evolution.

Accessories
Click Shield for Arduino UNO has two proprietary mikroBUS™ sockets, allowing all the Click board™ devices to be interfaced with the Arduino UNO board without effort. The Arduino Uno, a microcontroller board based on the ATmega328P, provides an affordable and flexible way for users to try out new concepts and build prototypes with the ATmega328P microcontroller from various combinations of performance, power consumption, and features. The Arduino Uno has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and reset button. Most of the ATmega328P microcontroller pins are brought to the IO pins on the left and right edge of the board, which are then connected to two existing mikroBUS™ sockets. This Click Shield also has several switches that perform functions such as selecting the logic levels of analog signals on mikroBUS™ sockets and selecting logic voltage levels of the mikroBUS™ sockets themselves. Besides, the user is offered the possibility of using any Click board™ with the help of existing bidirectional level-shifting voltage translators, regardless of whether the Click board™ operates at a 3.3V or 5V logic voltage level. Once you connect the Arduino UNO board with our Click Shield for Arduino UNO, you can access hundreds of Click boards™, working with 3.3V or 5V logic voltage levels.

Application Output
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.

* # Description
* This example demonstrates the use of IPD 2017 Click board by toggling the output state.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and logger.
*
* ## Application Task
* Switches on all output pins state for 2 seconds, then switches them off, and turns them on one by one.
