TinyDuino / No USB connection on Sierra
« Last post by nobsy on December 08, 2018, 06:12:40 PM »
On Sierra (iMac) my Arduino IDE does not show up a usb port for the TinyDuino. For my Arduino Uno the USB port is ok.
On Yosemite (MacBook Pro 13) the Arduino IDE shows up the usb port and everything works fine.
What is the trouble with Sierra?
Is this a known issue?
How can I fix this?

General Discussion / TinyScreen+ and TinyZero with 433 MHz long range radio tinyshield
« Last post by manor on December 04, 2018, 11:25:32 AM »
There was already a post about this: http://forum.tinycircuits.com/index.php?topic=1639.0 in 2016...
Basically, the demos still won't compile for M0+ (atsamd21).

Personally, I would be happy to use the "classic" tinyduino but the effective data rate when using the hardware along the lines of the provided demos is nowhere near the upperbound quoted in the documentation (256 kbps).

After all, any data transfer has to happen in blocks of (even in the original commented out version that's just 255 bytes at a time):

Code: [Select]
#ifndef RH_RF22_MAX_MESSAGE_LEN
//#define RH_RF22_MAX_MESSAGE_LEN 255
#define RH_RF22_MAX_MESSAGE_LEN 50
#endif

Without some trick for transferring data faster (is there some setting I am missing?), and given the need for a two way protocol to synchronized the data transfer I can't figure out a way to get above a couple hundred bytes per second, so I'm sure I am doing this wrong :-)

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

Yep- this was an unusual one.

We are definitely interested in adding your games! I need to go post in one of the Tiny Arcade section topics where you have mentioned the updates.

Sorry this sat so long! Yes, pin 3 is the only easily accessible PWM pin, MOSI/11 is one as well and seems to be labeled correctly in the image!

TinyDuino / Re: WiFi TinyShield, ATWINC1500-MR210B, Firmware Updater

Glad to hear it fixes the HTTP issue as well! We are now updating the firmware here as part of the test procedure.

TinyDuino / Re: Serial.read baud-rate issues...
« Last post by Ben Rose on November 28, 2018, 11:00:19 AM »
Just saw this one- For future reference, this is effectively a hardware limitation for the processor. The 8MHz ATmega(any that I've used) have a significant error in the baud rate generation when trying to do 115200. Why does it work one way? The FTDI chipset is 'smarter' and allows for receiving the significant error, but does not apply it back to what it sends to the TinyDuino.

There's another thread referencing the Arduino WiFi firmware updater tool not working. Same issue. I was able to modify the tool to run at 250K baud- much faster, but a rate that the 8MHz processor can generate exactly, so it works fine.

Unfortunately a lot of our older example code used 115200 since it was output only and worked fine. I'm switching things to 9600 as they need updates(when I remember!).

User Projects / Code Examples / Re: Simple implementation of TinySNAKE & TinySimon
« Last post by mjculross on November 27, 2018, 01:42:45 PM »
Found some time over the Thanksgiving holiday for some more refinements, so the source & binaries (suitable for SD card loading) for "TinySNAKE" have been updated.  The TinySNAKE "Demo Mode" now runs after a 10-second countdown (as long as START was not pressed) on the initial splash screen.  I shortened the length of the "beeps" to alleviate an occasional hang-up problem.  I spent most of the time improving the algorithm (again) for hunting apples in demo mode...writing the original game was a breeze, compared to the interesting challenge of writing the demo mode, or as one of my game collector friends calls it, "attract mode" from the arcade cabinet era, operations !!

As before, these updates 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

The source & binaries (suitable for SD card loading) for "TinySNAKE" & "TinySimon" have been updated.  Both now include rough-cut title screen videos.  TinySNAKE now includes a "Demo Mode" that runs after 5-seconds of no activity (START was not pressed) on the initial splash screen.

Updated versions are now available at the link described earlier.  The new versions include Ben Rose's recommendation for fixing the inconsistent volume when calling tone().
(see http://forum.tinycircuits.com/index.php?topic=1960.msg3972#msg3972 for discussion of the original problem)

I had some free time this weekend, so I took a stab at simple implementations of a couple of classic games.  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 !!
