Smart Sine - Software to generate sine table

  October 10, 2012    

There is an updated Python version of this now available, along with source code: https://tahmidmc.blogspot.com/2023/11/smartsinepy-and-example-of-gui.html

Here is the software Smart Sine, that I created and now use to generate sine tables.

It is the improved and more developed version of the software I had previously created with a few more useful features. It is relatively simple to use and gives results quickly as opposed to manually calculating the table.

If the software asks for .NET Framework Installation, you can download it from:


or


Download the software from :

    I'd like to use your program but when I downloaded it and ran it, it seemed to be infested with crapware that I don't want or need. Can you just have a copy of the executable on a virtual server or web space, rather than "free" file storage that is full of ads and add-ons and other junk? I think I'll just write my own program or use a spreadsheet. Nuch better and faster than dealing with this junk, IMHO.

    Congratulations Tahmid, I'm using your software and I'm very satisfied with it. Have you ever been asked to include a starting angle or, at least, to choose between sine or cosine? I know one can achieve this using a index offset, nevertheless, it would be great to have this feature in the software. The software is great, I am a huge fan.

    Hi Tahmid,

    Thanks a lot for the very useful tutorial!
    Is it possible to generate a faster Sin with dsPic33 ? So about 50KHz Sin Frequenz?

      It is possible. You'll need to keep in mind the PWM resolution you get and if that is satisfactory. In most cases, you'll probably be fine.

    Sir,
    I work with a 8 bit microcontroller. now for generating a sine wave , the values that i shall send to the DAC from the microcontroller , varies between '00' hex to 'ff' hex.... so how shall i get the negative part of the sine wave?

    I mean the output of the DAC will be between 0 volt to 5 volt.... I shall get the sine wave pattern but how shall i get the negative part...

    Should i use a negative clamper to get it???

    Hope u shall help me sir..

    Hello,

    Is there any way to download the software without having to use that crap website 4share or similar? there's like 400 ads on the page trying to trick people into downloading other junk software. Perhaps move it to your google drive? I just spent an hour cleaning all unwanted crap off my PC.

      Thanks a lot. and sorry.

    AoA.
    I m confused about how to create 8 bit sine table because I am using atmega8 timer2. Your smart sine generating values are greater than 255 if I increasing peak values greater than 250 v.plz help me I will thank full to you.

    Tahmid, Thanks, I used the sine table generated by your software to produce a waveform generator (square wave, triangle, sawtooth and sine wave) based upon PIC18F248 microcontroller allowing user input via PC/RS232 to select waveform, frequency and amplitude, and then use a MCP4921 DAC to output the desired waveform.

    Dear Tahmid,
    Greetings! Great job indeed!
    I have been also referring to your Sine Wave generation implementation using dsPiC33Fj publication. I have a small query as I too use the similar algorithm for my thesis but with dsPIC33FJ32MC202 very similar to yours controller. I would like to create a V/Hz control to vary my frequency linearly as a ramp function starting from a low volatge. Could you please provide me some valuable inputs or idea ont he same. I am using sine table with 4K values(one period) and 20Khz PWM, 20Mhz- Fosc.
    Thank you in advance. Keep up the good work!

    Can You add the calculation by RMS (each value * 0.707) & calculation by Average (each value * 2PI=0.637)?
