LM3915 Calculator

LM3915 Calculator is a small Windows application specialized in calculating the ideal resistor values for the LM3915 LED bar graph display using a set of straightforward actions.

You can store LM3915 Calculator on USB flash drives and run it on a target computer by simply opening the executable file. You can open the utility without administrative privileges.

It does not leave entries in your Windows registry and store configuration files in your system, so you can get rid of it using a simple deletion task.

There’s no support for a help manual but the dedicated parameters look easy to decode so you can venture into tweaking them on your own. A few details about the tool’s capabilities are shown directly in the primary panel. A graphical representation of the circuit is displayed in the GUI.

LM3915 Calculator gives you the possibility to calculate the ideal resistor values by providing information about the sensitivity (reference voltage) and LED current. What’s more, the application is able to perform reverse calculations and find out the actual LED current and reference voltage.

Tests have shown that the program carries out calculations very quickly and lets you copy the results to the clipboard. It runs on low memory resources so you can use it without having to worry that it burdens the computer’s performance.

LM3915 Calculator provides a simple and efficient solution for helping you perform calculations related to the ideal resistor values, and is suitable especially for engineers who work with an integrated circuit and need to visualize the value of an electronic signal. The only problem is that the application hasn’t been updated for a while so it may cause compatibility issues especially on newer operating systems like Windows 8.
