The collaboration between Zerynth and Mikroelektronika continues to churn out ideas and libraries. In this post we introduce you to the library for the BarGraph Click board.

Overview of the BarGraph Click

As you can see on the official page, BarGraph Click™ is a compact and easy solution for adding ten-segment light bar display to your design.

It features JSB-R102510Z light bar display as well as two 74HC595 shift registers. The 74HC595 IC contains an 8-bit serial in, parallel/serial-out shift register as well as 8-bit storage register. BarGraph Click communicates with the target board microcontroller via mikroBUS™ SPI (MOSI, MISO, SCK, CS), RST and PWM lines. Provided SMD jumper allows user to select whether the board will be powered with 3.3V or 5V power supply.

BarGraph Click is an excellent choice for VU meter design. The library  developed by the Mikroelektronika team also allows you to control LED light intensity over the set_intensity() method, using PWM.

Getting started with the BarGraph Click and Zerynth

To install the library just search “BarGraph” in the Zerynth Package Manager and click on the “Install” icon in the package view. If you have problems, please read this guide about how to search, add and update Zerynth libraries.
