General Discussion / FLASH for EEPROM
« on: May 13, 2020, 12:06:23 PM »
Is there a "simple" way to use FLASH, like on the TinyScreen+, as EEPROM for non-volatile storage for a few variables?  That is, without plowing thru gobs of code to find out how - just a simple function would be nice.


General Discussion / TinyZero Problems
« on: May 03, 2020, 02:47:00 PM »
I purchased two (2) TinyZero Processors and neither of them work correctly. I've tried them both per below.

Most times the Bootloader won't allow me to upload the code even after following the directions on the NOTES for the TinyZero.

But once in a while the code gets uploaded.

However, even when the code loads, the COM port won't be active after the loading sequence (see attached).

I did have another TinyZero (3rd one) that did work at one point, but the fragile bootloader button broke (tore off)

To confirm things....I've reloaded the Arduino IDE, changed USB ports, changed USB cables but still no luck.

Am I missing an #include <TinyZero.h> if there is such thing??

Any help will be appreciated.



General Discussion / Wireling Connectors
« on: February 19, 2020, 12:16:47 PM »
Is there a "PC mate" connector (female) to the 5-pin (male) Wireling connector - one that will allow a Wireling module with the 5-pin male connector to plug directly into a PCB without a cable?

Is there a Learn page for just the Wireling Adapter shield?


General Discussion / Communicating wtih Wirelings
« on: January 13, 2020, 08:46:58 PM »
How do you communicate with a Wireling module?

 I know it's I2C protocol and the library is probably <Wire.h> but what are the commands to do so?

For example, using a Wireling Adapter Shield connected to a TinyScreen+, how do you get information from a Moisture Sensor into Arduino code?  Are there addresses involved?  etc, etc.

Can you point me to a page(s) on the website that has this info?


General Discussion / Tinyscreen+ Driver
« on: November 23, 2019, 05:26:35 PM »
Windows 7 doesn't or can't find a driver for the TinyScreen+.

As such, no comm port can be assigned. 

Any ideas??


General Discussion / How to determine the width of a float number
« on: October 09, 2019, 12:34:57 PM »
I'm using the TinyScreen+ and would like to determine the width of a float number (with 2 places to the right of the decimal). 

Looks like you can do this with strings as in
  int width=display.getPrintWidth("Example Text!");

So is there a similar way to do it with float numbers??



I can't seem to compile the following in my TinyScreenPlus sketch Setup


It says 'serialUSB' was not declared in this scope.

Everything else I have works.

Here are the libs (below) taken from the example code for the TinyScreenPlus

Any suggestions???



#include <Wire.h>
#include <SPI.h>
#include <TinyScreen.h>

//Library must be passed the board type
//TinyScreenPlus for TinyScreen+
TinyScreen display = TinyScreen(TinyScreenPlus);
