General Discussion / Re: Duel Motor TinyShield Schematic Issue

« on: October 06, 2020, 12:42:46 PM »

John,

We do have 2-pin JST cables that you could solder onto a motor to use with the Dual Motor TinyShield: https://tinycircuits.com/collections/cables-connectors/products/jst-sh-2-pin-connector

We also have 3-pin JST cables for servos if you were interested in those as well: https://tinycircuits.com/collections/cables-connectors/products/3-pin-jst-sh-pigtail-100mm

Hope that helps!

John,

It looks like some recent updates went wrong on this page. I will fix them up today.

Thanks for the catch and letting us know!

TinyDuino Processors & TinyShields / Re: TinyScreen Smart Watch Compiler issues

« on: October 05, 2020, 12:09:04 PM »

Hello, 

The redefinition error is most likely due to downloading a library or arduino program and having duplication somewhere in your Arduino folders. I recommend going through and deleting all traces you have of the example and starting over with the libraries included above to make sure you have the right folders in the right places.

Hello,

I tested the Android ST example that you can download from the Smart Watch Learn page (https://learn.tinycircuits.com/Kits/TinyScreen-Smart-Watch-Kit_Tutorial/). Using a TinyDuino, USB TinyShield, ST BLE TinyShield, and TinyScreen, I had no problem uploading the program.

There are some warnings that will pop up during the upload, but I receive a "Done uploading" message after waiting. Do you have the right hardware? Does the program upload successfully after the warnings? Did you make any modifications?

I attached the program I used and the supporting libraries so that you can verify if you have the correct libraries downloaded.

Let me know how it goes for you.

Wirelings / Re: RobotZero DC motor difficulty

« on: September 28, 2020, 12:36:39 PM »

Glad to hear everything went well for you! In the next Rev, we are thinking there will just be some small software change for DC motors rather than the board modification.

As for the forum viewing, I wasn't aware of that! I am not sure if it can be altered with the security on the forum, but I will definitely look into it.

I will definitely take some time in the next few weeks to update the Learn page with the DC motor possibility for Rev3 - I am sure you will not be the last person to ask about the possibility.

Wirelings / Re: RobotZero DC motor difficulty

Hello,

First things first, always make sure you have a battery plugged in to power the motors (since their power supply is different from the VCC on the rest of the board). That may help resolve any issues with the Motor TinyShield.

As for the RobotZero, the first released revision does not directly support DC motors. The next revision that supports DC motors has been designed, but not yet implemented in production.

You can, however, cut some traces on the board in order to allow DC Motor control. I have attached an image that shows the two traces you would need to cut on the board. You can make these cuts with a sharp hobby/X-ACTO knife. After these cuts, it would be difficult to solder them back together even with the proper equipment - so you would not be able to use stepper motors after this modification. This is a good solution if you only care about DC motors.

For using the DC motors after the modification, I attached an image showing which pins to use on the RobotZero (the two pins closest to the battery port with power on the left, and ground on the right in respect to the attached image) and an example program with a new DC motor function to control DC motors.

I hope that helps!

Thank you,

Réna

TinyDuino Processors & TinyShields / Re: TinyScreen Smart Watch Compiler issues

« on: September 21, 2020, 02:55:42 PM »

Hello,

Sorry to hear about the errors. The first thing I would recommend is verifying you are able to program the TinyDuino using the TinyDuino getting started tutorial: https://learn.tinycircuits.com/Processors/TinyDuino_Setup_Tutorial/

The errors you have mean that there is an issue uploading the program to the processor board. The usual culprits are:
0. The micro USB cable you are using does not have the data wires to be able to program your TinyDuino - many micro USB cables that are used as chargers for electronics only have the power and ground wires. You can try using a few other cables if you have them.
1. The processor power switch is OFF and needs to be flipped to ON.
2. The Tools selections in the Arduino IDE aren't the correct selections for the processor you are using. You can find the correct Tools selections on the getting started page I linked above. Make sure you have the "3.3V and the 8MHz" option selected!

I hope that helps!

Let me know if you are still getting errors and if they change.

Thanks,

Réna

General Discussion / Re: TinyZero Board not recognized

« on: September 08, 2020, 01:09:23 PM »

Hello, I believe I already answered this in an email, but I will copy it here for community reference.

i) The beginning tutorial can be found here: https://learn.tinycircuits.com/Processors/TinyScreen+_Setup_Tutorial/
The different examples that flash on the screen are detailed with comments in the program to help you understand how to do what you are asking for. Basically, you will be generating arrays of what you want to put on the screen, and then you can display those array objects at the point (x-axis, y-axis) you program on the screen. The screen is 96 x 64.

ii) I would advise you to try the bootloader mode: https://learn.tinycircuits.com/Processors/TinyZero_Setup_Tutorial/#troubleshooting

Thanks,

Wirelings / Re: Multiple Soil Moisture Sensor Wireling AST1037 Sensors

« on: August 26, 2020, 01:09:59 PM »

Hello,

The Moisture Sensor Wirelings all have the same I2C address, I believe it is 0x30 - it is common for many I2C devices to have the same address amongst their copies.

To individually address each sensor, you would ideally want a multiplexer to be able to switch between different sensors with the same address. Our Wireling Adapter TinyShield, RobotZero, Wireling Pi Hat, and Arduino Wireling Shield all have a PCA9544 multiplexer (at address 0x70) for this reason. (The WirelingZero is a little different hardware-wise)

On top of the four ports available in a single Wireling Adapter TinyShield (that you can stack on any of our processor boards: TinyScreen+, TinyZero, TinyDuino) or RobotZero, you can add up to 7 more Wireling Adapter TinyShields while changing the address resistors (0x70-0x77) for a total of 8 boards, meaning a total of 32 possible wirelings per processor.

I hope that answers your question and gives you a little background on how we get around address conflict with I2C devices!

Thanks,
Réna

TinyDuino Processors & TinyShields / Re: Unable to Play Converted .tsv Files?

« on: August 14, 2020, 01:52:11 PM »

Hello,

Sorry to hear you're experiencing issues with the TSV Converter.

Do you still have all of the sample .tsv files on the SD card? I would recommend keeping those toward the top since that is what the TinyTV will play when first turned on, and testing new videos by adding them at the bottom of the list, or second to .tsv files you know work.

I would make sure the SD card is pushed all the way in (it can be hard to tell when inserting it into the TinyTV enclosure slot), and then make sure the SD & Audio TinyShield is stacked with the TinyScreen+. The 32-pin tan connecter could be loose which would explain the error -> No SD TinyShield, no .tsv files able to be read.

Let me know if that helps!

Thanks,
Réna

Hello Willem,

Can you link where you found this information?

The Telit firmware might not be open source, but I would be happy to look further into the firmware discrepancies and a possible fix.

Thank you,

General Discussion / Re: Recommended 3D printing materials and method

« on: July 27, 2020, 01:07:54 PM »

Hello,

Thanks for the suggestion, I will definitely add something to the product page with more information on how we get our 3D products printed.

We use the printing service JawsTec and print our TinyTV's and Smart Watch cases out of SLS Nylon, with the Default color option, and a raw finish.

I hope that helps!

Thanks,

General Discussion / Re: "Best" way to send sensor data via BLE?

« on: June 22, 2020, 02:02:56 PM »

Hello Tacca,

Have you considered using a Micro SD Card TinyShield? You would be able to save all of the necessary data with timestamps to be able to process it later.

I am curious about the range of Bluetooth on a runner.

TinyCircuits is in the process of designing a new processor board that includes a newer Nordic BLE module that may support the Data Length Extension you have mentioned.

Hope that helps give you some ideas on what you can do. In the future, I may have more time to look into the code you are currently developing to give better insight.

Thanks,
Réna
