Topic: Analog VU Meter - I2C OLED SH1106 - OLEDMeter Animation (Read 14709 times) previous topic - next topic

stievenart

I always wanted to do an animation of an Analog VU Meter on newer LCD or in this case OLED. I think the results came out well for a monochromatic display. I normally use a smaller SSD1306 display but it was too small for the details. All I need now is second display for both R & L channels.



I drew the background mask pixel by pixel using MSPaint. I then used Image2GLCD to convert the background mask to 128x64 and inserted it into the sketch. Free download at: http://www.ablab.in/image2glcd-software/

Nice! Have you seen the difference between an i2c oled display and SPI? This is a video I made of the difference after making two different boards: https://www.youtube.com/watch?v=SvOX-xs9v8M
Your meter could possibly be more responsive.

Nice job!

Thanks for the "nice" comments. I think the response time is better than real analog VU meters. Art imitating life has already been achieved. Please feel free to bring an SPI OLED video to the conversation.

Hello. Excuse my English, I'm doing the same project as OLED meter stievenart even with the same hardware, the problem I have with the software I used OLED meter .ino from Stievenart libraries but could you show error.Prosím someone was repeated I advise beginners and power do not understand, or if I sent the entire code Stievenart much I needed it or somehow advise I would be very grateful to you, please and thank you. :smiley-confuse:

Hello Choze,

Please send your question in your native language and I will have it interpreted.

Hello Stievenart,
I would like to ask you for complete source code of bitmap oled meter. It would help me much. Thank you.

Awful lot of lines of just 0's there. Can't you add a simple test and if the index to the array is <= 90  or >= 312 (whatever the 0x20 0x0F is at) then output a 0? Would save a lot of bytes.

Hi Crossroads,

You are correct, we could both easily add a loop to write up bunch of 0's... I just want newer users to understand you can use any image and "cut and paste" it into any .ino file. Besides, the code works great with them in it... you should try it. :D

Hello Stievenart,

OLED Meter not working,please complete source-code,hank you  Stievenart,
The code is complete... you need to load the libraries to make this work. This is not a beginner animation and you should try some basic Arduino codes first. Arduino is a learning tool and I am not going to hold your hand.

~Stievenart

I HAVE ATTACHED THE WHOLE CODE A SECOND TIME BELOW!

stievenart,


CHEERS!  :)  :)  :)  :)  :)

was searching the net for addtl info on VU meter with Oleds, when I stumbled upon your project. saved me LOTS of time coding  :smiley-wink:

done mine though with SSD1306, some minor changes on code, and viola!. will definitely "try" another VU image background

sorry for the dark image, did NOT want to use flash on phone, else I get incomplete LCD info. I hope attached image comes out right!

now on to some more tweaking! plan on adding this to an existing arduino VU meter (WS2812B) project, if addtl memory permits :)

 Ive done the said hardware with an Arduino nano clone, a 128x64 Oled (clone?) of ebay. careful with this one, some Oled displays have "NO ACKNOWLEDGE". ask me how I know  :smiley-confuse: but there are some fixxes to that.

define a single Digital pin as output, and use that PIN to power the display. problem fixxed! although u8glib has this done already.



Best Regards,
Ralph

VERY NICE RALPH! I was hoping someone would confirm the code. I have gotten a lot of traffic on this project. Thanks for posting a picture the OLEDMeter in action.

BTW, feel free to post your .ino with the u8glib version. I haven't tried u8glib yet and I am sure someone might need help with it...  :D
