Thumby / Re: Device *temporarily* boot-looped after visual artifacts in greyscale game

Well, my bad. It occurred to me to check if the battery was low, so I loaded the Battery application from the arcade, and according to it the battery was almost empty. If anything like this happens while the battery is reported as more full, I'll reply again.

That said: it would be a nice feature if the firmware performed a voltage check like that application does and displayed a low-battery icon in the early stages of boot, so the boot-loop that occurs at low battery would be less mysterious.

Thumby / Device *temporarily* boot-looped after visual artifacts in greyscale game
« Last post by dan5sch on November 30, 2022, 01:20:26 PM »
I experienced an odd failure mode on my brand-new Thumby after getting it yesterday. While playing a game that uses the greyscale display library (MineSweep from the arcade), a black bar appeared and began rolling vertically up the screen (like if you film a CRT). The bar was maybe four pixels tall and swept up the screen a couple times per second, though the speed changed over time as I interacted with the game. I assumed this was just a timing bug in the greyscale library's display control logic, so I didn't think much of it.

Then, after turning the device off and back on, it entered what appeared to be a boot loop -- the TinyCircuits splash screen appeared for a second, then the display went black for a second, then the splash screen appeared again, etc. But after leaving the device turned off for a few minutes, it turned on properly, and has worked so far since, including in MineSweep.

One final note: before this occurred, I had set the device right next to a cold window (20 F outside). No idea if this could affect operation.

If this happens again I'll record video.

Hi there,

Under the Downloads tab on the product page is a link to the manufacturer's specifications for the motor: https://www.vybronics.com/coin-vibration-motors/lra/v-g0832013d

Here's a link to the product page so you can check out any of our other resources: https://tinycircuits.com/collections/wirelings/products/lra-wireling-drv2605

Wirelings / LRA specification
« Last post by RickLi on November 26, 2022, 11:40:12 AM »
Hi,

Is there any specification to the LRA attached to the DRV2605 board available?
Frequency, voltage range, start and stop time, and impedance for example.

Many Thanks

TinyDuino Processors & TinyShields / Re: Need help with bluetooth interrupt signal

Hello, I believe you emailed in to our tech support, but I'll copy the answer here for anyone in the future with the same question.

For the software change, you will need to edit the STBLE library and change the pin number in the code to match pin 3 instead of pin 2. In the STBLE library that is downloaded with the example, navigate to STBLE/src/Arduino_hal.h – in this file, you will change BNRG_SPI_EXTI_PIN's value to 3 instead of 2.

Attached to this message is a screenshot of the highlighted variable - you will need to be logged in to the forum to see the attachment.

Cheers,
Réna

TinyDuino Processors & TinyShields / Need help with bluetooth interrupt signal
« Last post by lolsnub on November 18, 2022, 10:04:35 PM »
Hi, I am still new with tiny durino so still dont understand how to change the interrupt signal from R2 to R3.

I had used this guide https://learn.tinycircuits.com/Communication/Bluetooth-Low-Energy_TinyShield_Tutorial/ and shown:

NOTE:
The interrupt signal can be changed from pin 2 to pin 3 by removing resistor R2 and soldering it to position R3.

I had done the soldering to R3 but how to change the default from R2 to R3 base on the guide?

General Discussion / Re: Serial monitor not updating while connected to board
« Last post by lennevia on November 11, 2022, 10:35:19 AM »
Hi there,

Have you checked that the baud rate in the serial monitor matches what you have in your code?

It should be 9600 for both if you're using the code from the tutorial: https://learn.tinycircuits.com/Wirelings/Pressure-Humidity_Wireling_Tutorial/

Do you have any uploading errors? Did you program the correct processor board with the Tools tab selections?

Let me know!

Cheers,
Réna

Thank you!  I didn't have the file open in a tab on the editor.
