TinyDuino Processors & TinyShields / Push Button Issue
« on: July 17, 2017, 09:26:45 PM »
I am feeling incredibly stupid and after all the things I have made on my own, I cannot seem to get a simple push button to work correctly on the TinyScreen+. I have it connect to a proto board in which I am running a 10K resistor from 5v output to digital pin 5 and pin 5 also to my button. The other button lead to my ground. I have tested it with my multimeter and everything looks a go.

I've set pinMode(5, INPUT); and when I do a digitalRead(5), I get 0 no matter if the button is pressed or not. I have set the pin to HIGH and to LOW. Neither changes the results. I've read so many push button arduino tutorials and debugs, but I can't figure it. I have even used a different Tinyscreen+ just in case something may be wrong with the first's pin 5. What am I not seeing?

TinyDuino Processors & TinyShields / IDE Uploader Issues
« on: July 10, 2017, 10:45:18 PM »
I recently updated my board files including the one for the TinyScreen+in the Arduino IDE 1.6.8. Now I cannot get anything to properly upload to my TinyScreen+. I get a missing sam.h file message.

Arduino: 1.6.8 (Windows 10), Board: "TinyScreen+, Default"

In file included from sketch\Repulsor.ino.cpp:1:0:

C:\Users\Chris\AppData\Local\Arduino15\packages\TinyCircuits\hardware\samd\1.0.5\cores\arduino/Arduino.h:47:17: fatal error: sam.h: No such file or directory

 #include "sam.h"


compilation terminated.

exit status 1
Error compiling for board TinyScreen+.

What am I missing or doing wrong?

General Discussion / Wifi/Bluetooth

First and foremost, been a long time user and fan of Tinyduino as you guys have seen from my posts here. When a tiny form factor is desired, I look to you guys first. Recently, I dipped my toes into the darkside (Pi) due to the release of the Zero W. For $10, being able to get a processor, I/O pins, Wifi, USB, and Bluetooth, it is difficult not to least look at it. I was wondering if TinyCircuits had any plans to look at designing some more cost efficient boards in the area of Wifi and Bluetooth? Trying to add those in to a Tinyduino project quickly adds to the overall cost which makes me pause now with small size projects that may need multiple types of functionality.

TinyDuino Processors & TinyShields / Tinyscreen+, SD Card issue
« on: October 19, 2016, 06:51:01 PM »
I am using a tinyscreen+ with the IMU 9dof and SD card reader stacked together. Tried both the SD card info and the datalogger example (after setting the pin to 10). I am not getting any output at all. The serial baud rate is set to 9600. I send over a string to start, but getting no output back. Is there something additional needed to make the example work with the Tinyscreen+ over the traditional Tinyduino?

Tiny Arcade & Pocket Arcade / Shipping Status

How is the shipping of units for the Kickstarter progressing? See all the forum threads here, as a backer, I am super anxious to play too.

User Projects / Code Examples / Tiny Game Player
« on: December 07, 2015, 09:17:39 AM »
Thought I would share my old project revisited recently. When the TinyScreen came out, I got the Game Kit. It was a fun assembly that the kids liked, but left open it kinda got put aside. I finally got a chance to make a case for it. Made a small snap together case for it with Gamepad style top buttons. Added a keychain attachment to it as well so I can clip it to my coat or backpack. It was 3D printed on a small consumer printer. Still, it did the trick for me. Now I got a small bit of entertainment with me and a talking piece.

TinyDuino Processors & TinyShields / Tinyscreen
« on: December 19, 2014, 08:15:44 AM »
I know there is some details on the new Tinyscreen resolution and screen dimensions. Is there any information on the overall shield dimensions for it? Is it equivalent to the LED shields? I have a few screens coming from the Kickstarter campaign and itching with anticipation. I have a few standard casings I have 3D printed for projects and was wondering if I need to make any mods. Thanks in advance for any info.

TinyDuino Processors & TinyShields / On/Off Switch
« on: May 15, 2014, 11:08:57 AM »
I feel like I am a complete newbie here in asking, but what is the best way to add an on/off switch to the TinyDuino Processing Board? To maintain battery life, I would like to be able to turn it off when not in use. I have a nice enclosure for it, so I do not wish to have to have to pull open the enclosure and remove the battery each time.

TinyDuino Processors & TinyShields / Compass Shield Quandary
« on: April 16, 2014, 09:28:05 AM »
What is the expected output from the compass shield? I have connected the shield to the TinyDuino and ran the example sketch. Sure enough I am getting x, y, and z outputs on the serial monitor. Though now, it gets interesting...

1) If you rotate the instrument in place, the x, y, z numbers do change which is good. However, the values are not relative to each other. For example, the sum of their squares are not equal whether it is at 0 or 90 degrees. So is the sensor not calibrated in respect to each axis?

2) Using an LED shield for output to the compass, I get different values dependent on whether or not I am plugged into the usb shield with the serial monitor going or separate from the shield. Definitely makes debugging interesting.

3)Also noticed that on a few occasions, a small movement of the sensor causes the x to read -4096 which is worrisome. It does not seem related to actual magnetic field strength or orientation. This makes me think, I may have a faulty chip or it is not mounted correctly.
