General Discussion / Re: TinyScreen+ PIN breakout
« Last post by lennevia on Today at 04:36:37 PM »
Kon,

That's certainly the right connector that you would want to use - and it would work, but be a little difficult to handle and very fragile since the part is so small. For the pin breakout, it might be easier to consider a proto board TinyShield. These are the most popular: https://tinycircuits.com/collections/proto-boards/products/proto-board-tinyshield

But there are other options: https://tinycircuits.com/collections/proto-boards

I believe the Cyber Monday sale is going on until midnight today. so I'd recommend getting them while they're on sale!

We send out orders as they come in, but if you ordered a TinyScreen+ today, we might still have the order unpacked if you wanted us to add something!

Hope that helps!

Thanks,
Réna

General Discussion / TinyScreen+ PIN breakout
« Last post by kon-artist on Today at 03:30:00 PM »
Hi everyone,

I recently bought the TinyScreen+ and while I am waiting for it to arrive I wanted to get started thinking about the PIN breakout. I want to use the 10 pins available for ADC and thus idealy connect wires to those pins directly. However, I found on the schematic that the part being used for the pin connector is "DS12-32-DP". Would this https://www.digikey.de/product-detail/de/hirose-electric-co-ltd/DF12A-3-0-32DS-0-5V-81/H5202DKR-ND/1844301 connector fit to get what I want? Any other suggestions? Remove the pin bed altogether?

Thanks for your help!

Cryptoxic,

Were you able to get the TinyScreen working?

General Discussion / Re: TinyScreen+ stuck in Bootloader Mode

Glad to hear you could sort it out!

It seems restarting everything usually seems to do the trick for most electronics  ;)

Hi John,

yes, it is possible to get data from my test flights.

Please send me an e-mail (see members list) with an indication of the planned use.

With respect to BMA250 range and bandwidth, I used +/- 16 G to avoid saturation and BW 31.25 Hz (update time 16 ms).

The LSM9DS1 accelerometer is using much more bits, also + / - 16 G setting and ODR 50 Hz.

Just a note:

Because the model rocket fincan has canted fins, it also rolls (along its length axis) with a rotation rate depending among others on the forward velocity . This offers the possibility to test the gyro and the magnetic sensors.

The accelerometers are not positioned at the center, so the roll rotation also gives a significant centripetal acceleration to AccY and AccZ of BMA250 and AccX of LSM9DS1.

AccX of BMA250 and AccY of LSM9DS1 provide data of the forward acceleration of the model rocket including the rocket motor activity.

Regards,
Willem

General Discussion / TinyScreen+ stuck in Bootloader Mode
« Last post by JohnB on November 21, 2020, 01:07:06 PM »
Hi,  I'm new here ;)  Could anybody advise.  I would really appreciate it. 
I have a Tinyscreen+ which seems to be stuck in Bootloader Mode.  I have a few Tinyscreens+ and have recently been trying to establish IR communication between them so I may have damaged it but I'm not sure.  I have tried to  load an empty sketch to unlock it and sometimes it does seem to unstick itself but then it flicks back into Bootloader Mode as soon as I try to load anything that tries to bring it back to life.  It there anyway of resetting it?
Please excuse my ignorance. I am an engineer but have not programmed for a while now  :)
Thanks.

PS when trying to upload I get "Locked" appearing in the error report.

PROBLEM CLEARED 😄. I think it was a coms port issue. I am using a usb hub. Once I restarted everything and plugged direct to motherboard it cleared.

WillemH,

Would it be possible to acquire your BMA250 accelerometer csv files from your test flights?

- acceleration (3 axes simultaneously) and temperature of BMA250 on TinyZero,

Also, what were your bandwidth and acceleration range settings at the time.

Thanks,

John

This is awesome! It's great to finally see pictures of the tiny rocket!

We are looking to hopefully release the ZOE GPS TinyShield on our website sometime in the next few months. Thanks so much for putting it to good use and reporting back on your findings!

Looks like the picture link got broken from an edit on the product page.

I will build the site later today to get it fixed. Good find!
