TinyDuino Processors & TinyShields / Re: TinyScreen+ Screen Orientation (Portrait)

« on: April 22, 2018, 05:48:52 PM »

This may be obvious, but I solved a similar problem by rotating the image in the source file before I converted it to .tsv.



Hi, I also want to display .tsv files in a portrait mode. Can someone advise on how to do this? Thanks!

General Discussion / Charging Tinyscreen+ and Battery

« on: January 25, 2018, 01:51:30 AM »

Hey Folks - So far, I have always recharged the Tinyscreen+ battery via my Mac's USB port.  Is it possible to use a wall wart with a microUSB plug instead?  I wondered if I could use the charger that I use with my Pi.  It puts out 5v at 1600 mA.  I believe the TS+ says it wants 200 mA.   Will that work?   Thanks.

TinyDuino Processors & TinyShields / Re: tsv on tinyscreen using 'TS audiovideosimple'

« on: December 20, 2017, 08:05:48 PM »

I have a stable image on the screen now.  But it's not moving.  Just playing a single frame.   

If anybody could help me get the last few feet on this, I'd really appreciate it.

Thanks.

TinyDuino Processors & TinyShields / tsv on tinyscreen using 'TS audiovideosimple'

« on: December 18, 2017, 08:24:31 PM »

In another topic I described the roadblock I hit attempting to use the sketch 'Tinyscreen Video Player' (a Tinycircuits sketch dated 2015).

I've had a bit more success using a new sketch, called Tinyscreen AudioVideoSimple (a Tinycircuits sketch dated June 2017).  This time, I get an image, but it has some issues.  It is 'multiplexed' (?) (ie, appears multiplied 3 or 4 times on the screen and is not playing at the expected framerate, and possibly not in the expected color space.   

The multiplexing is the biggest problem for me.  If I could get it to display the full frame, I could possibly solve the color issues and maybe the frame rate by preparing the video differently before using the TSV converter.

Can anyone advise me how to refine the playback?

Dec 19th:

I made some progress with this by tweaking values in display.bitDepth and writebufferDMA.  I got the image to stabilize and display the correct colors, but there was still some flickering and I'm not sure whether it was playing multiple frames or just stuck on one.   

If anyone can clue me in to what these values are really doing, and which ones I should focus on, that would be a big help.

Unfortunately, I've had so many problems with the Mac's USB serial port issue that I'm not really moving forward anymore.   Will probably try running the IDE on my raspberry Pi instead... see if that works any better.

PS: I think I have probably posted this in the wrong category.  If anyone knows how to move this message to the right place, feel free.

General Discussion / Re: Movie player with Tinyscreen+

« on: December 18, 2017, 03:09:01 PM »

Hey Ben - How did you get this working?  I have been trying for 4 days to play a movie (at any speed) on Tinyscreen+.    Any clues would be great.  Thanks.

TinyDuino Processors & TinyShields / show tsv clip on tinyscreen+

« on: December 18, 2017, 02:04:29 PM »

I want to show a .tsv movie on tinyscreen+, playing off an attached microSD card.  I'm following the steps in this Tiny Circuits article: "Putting Images on Your Tinyscreen" https://tinycircuits.com/blogs/learn/120988679-putting-images-on-your-tinyscreen.

———————

1) I'm running the desktop IDE on a Mac. 
2) In IDE Tools menu, Tinyscreen+ is selected as Board, and the Port selected is dev/cu/usbmodem. 
3) The devices, plus the recommended battery, are attached to my Macbook Pro via USB.
4) Using an adapter, I put the microSD card in Macbook and copied "color.tsv" (test file from the article) to it.  Moved microSD card to the card reader attached to TS+.
5) Turned on TS+ stack.  Amber light goes on, then turns off after a while (does this mean battery is charged?).
6) Downloaded Tinyscreen Video Player.ino from the article.  (This is dated May 9, 2015.  Is there a newer one?  (There are several on GitHub but can't tell if any are newer or better.)
7) Opened  Tinyscreen Video Player.ino in IDE. Pressed Upload button.  Got the following error message:

--------

Arduino: 1.8.5 (Mac OS X), Board: "TinyScreen+, Default"

/Users/tsanders/Downloads/20171218/TinyScreen_Video_Player/TinyScreen_Video_Player.ino: In function 'void loop()':
TinyScreen_Video_Player:38: error: 'class SdFile' has no member named 'getFilename'
     if(fileInfo.isFile() && fileInfo.getFilename(filename)){

                                      ^
exit status 1
'class SdFile' has no member named 'getFilename'

---------------

I am a complete newbie, so if this requires a change to the sketch, please be very specific.   Thank you.

---------------

Ultimately, I want to be able to just switch on the TS+ stack, and have my tsv movie play from the SD card.

Any guidance would be appreciated.   Thanks!
