TinyDuino / WiFi TinyShield, ATWINC1500-MR210B, Firmware Updater

« Last post by tom on November 18, 2018, 08:15:43 PM »

Hello,

I am trying Tinyduino + WiFi TinyShield, ATWINC1500-MR210B + WiFi101 ver 0.15.2 with Mac OS X.
When I run CheckWifi101FirmwareVersion, I got this output.

WiFi101 firmware check.

WiFi101 shield: DETECTED
Firmware version installed: 19.4.4
Latest firmware version available : 19.5.4

Check result: NOT PASSED
 - The firmware version on the shield do not match the
   version required by the library, you may experience
   issues or failures.

As instructed, I added this;

Code: [Select]

WiFi.setPins(8, 2, A3, -1);

Then, I tried FirmwareUpdater. I didn't see any output from the serial port. And then, I closed the serial monitor, and opened WiFi101 Firmware Updater.

I selected /dev/cu.usbserial-DM01MY0V which is the one I am using for the software downloading, and clicked 'Test connection' button, but I got Connection error. dialog with "Programmer not responding".


I am not sure if I need to add WiFi.setPins and where to add, but I tried both, with and without WiFi.setPins right after the Serial.begin.


I have an issue for HTTP communication. After rebooting, the first access and the second access work, but the third access don't work for my server. It works for www.arduino.cc, so there may be another issue, but I am wondering if updating the firmware solves this issue.

Hope someone can have the answer.

TinyDuino / Video Player with Tinyscreen & MicroSD TinyShield

« Last post by Newbie1234 on November 15, 2018, 11:08:55 AM »

Hi, I am trying to make a video player with the Tinycircuit.

The parts I have are:
TinyDuino Processor
OLED TinyScreen
TinyShield USB
TinyShield MicroSD
MicroSD Card and Reader

I tested out my TinyShield MicroSD and it's working fine, I am able to read files and open them.
Color.tsv is displayed as shown in the link.
https://tinycircuits.com/blogs/learn/120988679-putting-images-on-your-tinyscreen

However, when I tried to make my own tsv file using this tutorial https://tinycircuits.com/blogs/learn/tsv-video-converter-tutorial to convert mp4 to tsv files and load it into the  TinyShield MicroSD card, the tsv files when played is always glitching and flickering as shown in the attached photo.

Is there a limit to the video in terms of size/ frame rate pixels etc? How to I rectify this issue?

Hope someone can provide guidance!

Tiny Arcade / Re: How big is the TinyArcade screen size (In pixels)

« Last post by mjculross on November 12, 2018, 12:59:10 AM »

The TinyArcade uses the TinyDisplay, which is 96 pixels wide by 64 pixels tall, & is capable of displaying 16-bit color.

User Projects / Code Examples / Simple implementation of TinySNAKE & TinySimon

« Last post by mjculross on November 07, 2018, 09:11:05 PM »

I recently ordered & received a PocketArcade kit.  After downloading & installing the ZIP collection of games, I was inspired to try my hand at implementing my own simple versions of TinySNAKE (aka Nibbles) & TinySimon (aka memory).  The source & binaries (suitable for SD card loading) for "TinySNAKE" & "TinySimon" (no title screen video yet for either, but they do still show up in the initial menu system) can be found in their respective folders under the "PocketArcade projects" folder in my Google drive at the following URL: https://drive.google.com/open?id=1Pv0LDGhe3uLNJvhF7-aSdTOSZMYe8hbx

Enjoy !!

TinyDuino / GPS Tracker

« Last post by donde on November 07, 2018, 06:31:36 PM »

Can't get past this point. On Serial Monitor, I see:

Initializing Flash Memory...

Determining write/read start point...
Done.

Send 'y' to start read mode. Write mode will begin in 10 seconds...

Now initiating write mode.

Attempting to wake GPS module..

I GPS shield works, for just was using it for another tracker, The Cat Tracker. It of course uses an SD card shield. I substituted the SFI Flash shield. The 2 Includes I'm using are
#include "SoftwareSerial256.h"
#include <SPIMemory.h>
I tried 4800 for GPSBaud speed instead of 9600
The 4 boards are from top to bottom
GPS
USB
Flash
Tiny Duruino

Please help

I already have 4 stacked boards for GPS logger. I would like to start another stack with your special cable that will connect to the WiFi board. It requires a Tinyduino and USB board. Can I use these existing boards from the 1st stack?

Tiny Arcade / Send voltage to expansion shield pin?

« Last post by Grant349 on November 03, 2018, 03:49:09 PM »

I've been working on a project that uses a tinyscreen+ in combination with a thermocouple board from adafruit (MAX31855).

This TC board needs an external power source to run, and I've been trying to send voltage from the tinyscreen+ to the MAX31855 through a tinycircuits expansion shield to accomplish this, but I've been unable to get any of the pins I've tried to send voltage.

I used digitalWrite and analogWrite for pin 13, in addition to hooking up VCC and VIN pins to the VIN or 3Vo pins in several combinations (which in my experience, VIN/VCC with arduino boards usually don't require inclusion in programming to send power), and none of them sends power to the MAX31855.

Is there specificity to which pins can use the digitalWrite or analogWrite functions on a tinyscreen+ expansion shield like other arduino boards? Is VCC or VIN on the expansion shield supposed to send either 5V or 3.3V automatically? Is there another foolproof way to send voltage from a tinyscreen+ through the shield pins that I'm not aware of?

General Discussion / Re: volume not consistent when using tone()

« Last post by mjculross on October 31, 2018, 02:09:34 PM »

Ben:  Thanks for the reply.  The source & binaries (suitable for SD card loading) for "TinySNAKE" & "TinySimon" (no title screen video yet for either, but they do still show up in the initial menu system) can be found in their respective folders under the "PocketArcade projects" folder in my Google drive at the following URL: https://drive.google.com/open?id=1Pv0LDGhe3uLNJvhF7-aSdTOSZMYe8hbx

Both of these play a quick "charge" sound at startup, & have additional sounds in the game.  All of these sounds are simply calls to tone() / delay() / noTone() & should easily show the reported symptom.  It does seem that if the PocketArcade has been off for some time, the volume is usually louder, but not always.  However, as soon as power is cycled, that's when the volume is definitely decreased & becomes inconsistent.

Let me know if you need anything else & thanks again !!

Can you post a really basic test case that results in this behavior? I think I remember seeing this when using tone, but don't remember the cause so I'll have to reinvestigate.

Thanks,
Ben
