With some assistance from TinyCircuits, I was able to find the correct Header that will mate with the boards. The ones I ordered from Mouser ( the stocking ones ) are incorrect. I ordered them from DigiKey. Part number H5205CT-ND. They also have the mate for it, but i didn't order any.

I was watching the commercial and noticed that was TinyCircuits microcontroller. I'm not sure how it saved the mainframe, but that's what imagination is for :)

General Discussion / TinyPod - TinyScreen+ as a Music Playing Interface
« Last post by MilLs Dj on September 29, 2018, 02:03:25 PM »
Hi all,

I'm becoming a fan of these tinycircuits, but I am a novice when it comes to writing my own code. I received the Tiny Saber kit as a gift and loved it. I purchased the tinyscreen+ in to tinker with what I can get from it. I saw the smartwatch and video player builds for the tinyscreen, but I wanted to put both the saber and screen inside an old Nintendo Gameboy for music making purposes.

The main goal is to have the TinyScreen have its own music selection screen, reading the .mp3 or .wav files from the Micro SD card. And when the song is playing, have a screen that displays:

-track playing (Name, Duration)
-Song time code (00:00:00)
-progress bar of song playing (time left in song and time point in song)
-Pause option (ability to continue playing song selected if returned to the music selection screen)
-exit song playing screen to get next song ready to play (song plays next immediately after or through cross fade)

The visuals below show what I'm looking for. They follow the pixelXpixel (96x64) tinyscreen+ display.

---Music Selection Menu---

Basically the same as the video player menu, Name of files from SD card shows with an arrow that can scroll down between them.

-Upper Left Button- move arrow up

-Bottom Left Button- move arrow down

-Upper Right Arrow- Select song, start playing song, move to Track Playing Screen. If the song that is playing is the file selected, song restarts.

-Bottom Right Arrow- when pressed, the file that the arrow is currently gets highlighted a color (TBD color, yellow, whatever...) to show that that is the next song to play IF the arced arrow is shown in the Track Playing Screen.

If a song is playing and there is inactivity for 10-15 seconds on the Music Selection Screen, it moves to the Track Playing Screen.


---Track Playing Screen---

-Upper left Button- the top left Square ( Stop ) alters via upper left button press to go to next song after the current song is finished and stop playing after song ends (return to menu selection screen). When the arced arrow is shown ( play next song on SD Card at the end of current playing track) at the bottom, the next song that will play is shown.

-Bottom Left Button- when pressed, goes back to menu selection screen, the music still plays though, like an ipod does

-Upper Right Button- cycles, when pressed, between crossfade audio tracks at the last 3 seconds into the first 3 second of the next song and "hard play" which is one after another, no overlap ( normal ).

-Bottom Right Button- pause and play, when pressed pauses, pressed again continues playing

-Progress bar.. you know what this does

I know this is possible with the TinyScreen, given the video player, smart watch, and Tiny Tetris builds, but I'm not sure where to start coding wise. Anyone lend a hand? This is my end goal, but any process of getting the Tinyscreen and microSD Shield to play my music between 2 screens ill be happy.

Thanks!

General Discussion / linux code upload and modemmanager
« Last post by littlejohn on September 28, 2018, 05:18:03 PM »
Another issue I had, just FYI:

I had alot of trouble uploading code to tinyscreen+ on Linux. Half the time it would fail or tell me the port was busy. This is due to ModemManager scoping out any serial ports to see if they are GSM modems. You can fix this by putting a udev rule something like this in /etc/udev/rules.d/77-arduino.rules

# stop modemmanager from checking every serial port for a modem.. it locks up the port
# for a few seconds and interferes with uploading.
#
# arduino
ATTRS{idVendor}=="2a03", ENV{ID_MM_DEVICE_IGNORE}="1"
# tinyscreen / atmel
ATTRS{idVendor}=="03eb", ENV{ID_MM_DEVICE_IGNORE}="1"

...as described here:

TinyDuino / Windows 7 not identifying tinyduno when plugged in
« Last post by dana8080 on September 28, 2018, 05:00:40 PM »
Hiiii,
I have been following your guide on how to upload video to the Tiny duino, when I get to the part where I need to go into device manager and check the "unknown device" area, I cant because there isnt an unknown device plugged in as far as windows in concerned.
I have tried:
Updating all drivers from Windows
Updating all drivers from my computer manufacturer (lenovo)
restarting
different USB ports
plugging-re plugging the tinyduino shield 110x

I am now trying to reboot the sheild but your documentation says "hold down button closest to the usb port and turn the switch back on", but there are 2 buttons the same distance from the usb and it doent seem to matter what combination i press, nothing happens, I just get the standard video the thing came with.

When its plugged in and the slide is off, it blinks orange, when its on its solid green.

Please help, is there a reset pin or gnd pin on this thing?

It is connected:  screen -> Usb -> tinyduino

Thank you

General Discussion / Stacking Connector
« Last post by whmckinley on September 22, 2018, 01:24:17 AM »
I am building a expansion module for a TinyScreen+ for use in a Refrigerator Thermostat project. I tried the HIRose stackable connector DF12-32DS-0.5V(86) , for the expansion male connector. It does not seat fully into the TinyScreen+ female connector, OR ANY Tiny Circuits Female stackable connector.

Trying to find a source, part# for a correctly mating connector.

I don't believe there is anything in the TSV file that specifies duration. I'm guessing that setting a duration would mean it just includes a copy of that image enough times to make it last for that duration which would make the file size larger.

I don't have experience with switching bitmaps on a button push like you're trying to do. However, I believe the quick switching between images is something controlled within the TSV Converter. There should be a "Duration" option that controls this. Now I know this doesn't necessarily solve your problem, which brings me to this next question: are you only going to be working with still images on this project? If so, you may be able to create "sprites" to act as these images for easier switching upon a button push. There may also be another option with the code found within the "TSV Converter Tutorial," however, I haven't explored that much myself.

Let me know what you think!

TinyDuino / TinyScreen+ Physical dimensions
« Last post by whmckinley on September 20, 2018, 01:32:00 AM »
I have been building a Thermostat project for the refrigerator in my RV. The circuit is built and tested as functional. It is comprised of a TS+ with a custom expansion board which contains the added circuitry and switches. I am beginning to layout a cnc milled enclosure. From a previous topic, TS+ eagle files, and the data sheet for the display module, I was able to get the required thicknesses and basic measurements. but am still missing a few key measurements.

I am looking for the measured placement of the display module on the TS+ board. The TS+ board is 25.0 x 25.8, the OLED itself is 25.70 22.20, the OLED viewable area is 20.14 x 13.42. Primary question, what are the X,Y coordinates of the bottom left corner of the Viewable Area in relation the TS+ Circuit board 0,0 coordinates.

I would appreciate any assistance.
