General Discussion / Re: MicroSD TinyShield Problem

« on: April 28, 2021, 12:12:53 PM »

All,

After some preliminary model rocket tests, I'm dropping the SD Card in favor of your EEPROM shield.

The reason is that the SD Card can't seem to handle vibration or shock in a model rocket application, while (I assume) the EEPROM shield will (I haven't tried it yet).

While the memory size of the EEPROM is far less than the SD Card, the demanding need is for reliable data storage, which I hope the EEPROM will provide.

I'll get back to the SD Card for other applications, so thanks for all your advice and suggestions about this device!

Thanks All,

Yes...I'm using pin 10 for CS and, also, about the tutorial.

But it looks like I "may not" be giving it sufficient time to respond.

I'll let you know.

General Discussion / MicroSD TinyShield Problem

« on: April 24, 2021, 07:32:57 PM »

I have a MicroSD TinyShield  along with a TinyZero Processor Board.

Do these work together?   

The reason for asking is because the MicroSD indicates pinouts for the TinyDuino Processor Board  and not the TinyZero.

Is there a compatibility issue with the Arduino built-in SPI.h as nothing seems to work in terms of reading and writing to the micro SD card.

Any help will be appreciated.

Thanks,

John

Has anyone used the 2.4GHz or 433MHz boards for locating objects in the field...like model cars, drones and, especially, model rockets? 

I'd be interested in knowing your results and whether the 2.4GHz or 433MHz board is "best" - read "able to better locate the object"

Thanks,

Doppelganger,

I'm also looking forward to your experiences with this device, as some non-technical types have asked me how to upload videos to this unit.

Any news as to when the ZOE GPS TinyShield will become available?

Any details on same would be appreciated so we can plan on implementations.

Thanks...john

Ben,

How can one charge the battery if the UART (USB port, I assume) is being used for this board? Let me know if I'm off base on this.

BTW, a 20mm x 20mm board would be fantastic!

Thanks,
John

"With my model rocket application with UART only I have shown that it is not strictly necessary to have access to the I2C, ]but access to both UART and I2C will certainly increase the attractiveness of the new board"

I concur...john

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

Please ignore the preceding question about the Wireling ....I found the answer to my coding questions in the Large Button section https://tinycircuits.com/collections/wireling-input-output/products/large-button-wireling  under Software.

It works!

Sorry for the intrusion,

General Discussion / How To Access Wireling A0 - A3 Ports

« on: October 28, 2020, 02:57:40 PM »

I have a Wireling Adapter TinyShield   ASD2022 (only one) connected to a TinyZero Processor Board      ASM2021-R-A

I am trying to access either A1, A2 or A3....A0 is used for the 0.42 OLED that seems to work fine. 

Here's part of my code....

Defining the pin
const int       apb   = A1;                   //use A1 as the altitude push button (apb)on the Wireling

Trying to access the analog value
  Wireling.selectPort(apb);                //Select Wireling port
  apb_value = analogRead(apb);             //get the value of the analog port

When opening or closing a push button on this port, I get the same analog value (15 out of 1023)

What do I need to do differently?

Thanks,
John

General Discussion / More Dual Motor Board Software Questions

« on: October 20, 2020, 06:35:41 PM »

Are there a (complete) set of motor commands as hinted in the "TinyCircuits Dual Motor Driver Basic Example"

for example...
  motor.setFailsafe(1000);
    motor.setMotor(1,i);
    motor.setMotor(2,i);

Are there any more like this??

Thanks,
John
