Status:
Pulse Click is a compact add-on board that provides a pulse generator with an adjustable frequency. This board features the NE555, a precision timer from Texas Instruments. It can produce highly accurate time delays, while its frequency can be configured in just two steps. As a resulting output, this Pulse Click can be configured to have these delays as a digital output frequency or as an interrupt. This Click board™ makes the perfect solution for generating a pulse with precise frequency control for equipment testing and similar purposes.
Pulse Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Availability date:
Pulse Click is based on the NE555, a precision timer from Texas Instruments. The NE555 is a well-known piece of silicon and features timing from milliseconds to hours, astable or monostable operation, adjustable duty cycle, and more. The Pulse Click features several potentiometers and a switch for adjusting the desired frequency. The frequency selector switch has four positions, starting from the six-o-clock position and moving clockwise in quarters, thus selecting one position from 0 up to 100Hz, 1 up to 1KHz, 2 up to 10KHz, and 3 up to 100KHz. After choosing the appropriate position, you can move to onboard A and B side potentiometers to fine-tune the desired frequency. Over those four potentiometers, you can go in fine steps from its start point up to final value.
The output of this Click board™ can be configured as an interrupt on the INT pin of the mikroBUS™ socket or as a digital output over an OUT pin. The user must select the proper OUTPUT FUNCTION jumper as an OUT or INT, where OUT as a general-purpose analog/digital output is set by default. In addition, this board features a pulse LED indicator and an HD1 2-pin header if the user wants to use the output of this board in some other way than via the mikroBUS™ pin.
This Click board™ can work on 3.3V and 5V but the output voltage must be set over the OUTPUT LEVEL jumper between those two voltages, as the 3.3V is set by default. For this purpose, the Pulse Click caries an SN74LVC1T45, a single-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs from Texas Instruments. However, the 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.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all Mikroe compilers.
This Click board™ is supported with mikroSDK - Mikroe Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
