Solved!

Just updated to the new SPIMemory library and all works brilliantly now!!

TinyDuino / Re: Access GPIO's directly from expansion port
« Last post by thesko on May 23, 2018, 05:12:39 PM »
Ok found my own answer:
Yes.

The pins available on the proto boards are directly accessible on the expansion port.
It is very tricky and difficult to solder to, but possible.

My approach:
I've used the plug of another board, removed all pins but the one GPIO I wanted to use and the two GND pins, then soldered the buzzer to the pins and plugged it in. Works flawlessly :)

New Product Ideas / Re: Whatever happened to those new products?
« Last post by thesko on May 18, 2018, 10:26:18 AM »
So.. any update on that by now? I could make good use of flatter versions of the stack compared to the current setup I have with the TinyScreen+.
The only mentioned new productions I could find are the Blog post from April:
https://tinycircuits.com/blogs/news/new-products
I guess the image at the end of the post is supposed to be a teaser?

Will the new product line also include an update to the TinyScreen+ to support the new connector?

TinyDuino / Access GPIO's directly from expansion port
« Last post by thesko on May 18, 2018, 10:07:27 AM »
Hi,

I'm working on a project involving the TinyScreen+ and the EEPROM board.
I plan to remove the bottom expansion port of the EEPROM board to save some millimeters in space. and this way can access the pins easier, which brings me to my question:

Is it possible to hook something up to the IO8 pin (25 on the connector) directly?
I plan to attach a piezzo buzzer for 8 bit audio and want to save as much space as possible.

User Projects / Code Examples / Re: 433MHZ Long Range Radio TinyShield examples
« Last post by thesko on May 18, 2018, 09:20:11 AM »
Hi, I'm waiting for two of the 433MHz transceivers to be delivered and started to look into this as well.
For now I could not find any Tinyduino-specific examples, but I've stumbled upon this library:
https://andreasrohner.at/posts/Electronics/New-Arduino-library-for-433-Mhz-AM-Radio-Modules/

It looks promising.
It's supposed to be an alternative to the existing VirtualWire and RadioHead libraries. VirtualWire seems to be not maintained right now and RadioHead is a bit complicated to use imho.

I'll post an update when I have received my own devices or if I find any other solutions.

TinyDuino / Re: Tinyscreen+ Vbat reading
« Last post by thesko on May 18, 2018, 06:49:11 AM »
Hi, I would also like to know how this could be done!

The only information I've found so far are rather complex "hacks" to estimate the data:
https://codebender.cc/sketch:91833#TinyScreen_Smartwatch.ino
(look for the displayBattery() function)
http://forum.tinycircuits.com/index.php?topic=1599.msg3087#msg3087
(more or less the same as above)
http://forum.tinycircuits.com/index.php?topic=1412.msg3419#msg3419
https://gist.github.com/KhanradCoder/d016330a9b69bf7c659a


Is there an achievable way of modifying the TinyScreen+ board to get a voltage readout of the battery and maybe even a charging state?

Can some of the TinyCircuits staff help here?

Does anyone have an example of a simple sketch that is definitely working for writing data on the flash shield so I can further investigate my problems?

Hi,
Why not use the millis() function?
https://www.arduino.cc/reference/en/language/functions/time/millis/

This gives you (at least) a timestamp in milliseconds (and then buffer in an array of datapoints before writing on the SD card).
Cheers

TinyDuino / Problems writing on Flash Memory TinyShield
« Last post by PSch on May 14, 2018, 11:21:00 AM »
Hi,
I have problems writing on the Flash Memory TinyShield using the example code TinyShield_FlashMem_Example.ino or any other example code I found (I tried to modify the GPS tracker example).
For testing I just run the ASM2001 Rev9, ASD2101 Rev6 and ASD2202 Rev3 (flash) shields.
I updated the SPIFlash library but still no success.

Can anyone help?

I get the following output:

                              Important Notice

               This version of the library - v3.1.0 will be the last version to ship under the name SPIFlash.
            Starting early May - when v3.2.0 is due - this library will be renamed 'SPIMemory' on the Arduino library manager.
                     Please refer to the Readme file for further details.
