I just purchased a tinyduino ASM2001-R-L (with the lithium battery option) and a tinyshield ASD2101-R.  I plugged in the battery, turned on the switch, and then connected my tinyshield.  The light on the main board comes on - and that's all that happens.  There's no response from the system showing this board.  I installed the software/drivers, but I don't see it.  This cable is definitely good; I tried two other cables, but the board LED doesn't come on with them; with this cord, it does.  I'm assuming, therefore, that the cable is good.

Any ideas why this isn't being detected?  I already have a device on COM3; do I need to remove it?

Hello,

Are you able to see a COM# in your Device Manager when you plug in and unplug the device? If a new COM# port isn't showing up when you plug the unit in, either the cable does not include the necessary data wires for programming, or the TinyDuino power switch is not turned to ON.


As for the drivers, are you using Windows 7?

Let me know! Thanks.

I'm using Windows 10.  There's only 1 COM port listed (COM3) and my Prusa I3 MKIIIS is using that.  The software seems to be stuck on COM3, with no way to change it, and nothing else is showing up.

I tried 1 USB cable, and nothing happened; on the third cable, the light on the board came on; is it possible that this cord is STILL not correct?

It is possible that the USB Cable is still not correct. A new COM# should show up when the TinyDuino power switch is ON (it may help to double-check this), and when the cable is working. You can check that the cable is working by opening the Device Manager and plugging and unplugging the device, as seen here: https://learn.tinycircuits.com/Help/Port_Trouble_Tutorial/

On Windows 10, you should not need to download any drivers - separate downloadable drivers are only noted for Windows 7 users in the TinyDuino tutorial.

You should not need to remove the device on COM3 if you have more USB ports to plug the TinyDuino into. From the Arduino IDE Tools menu, you will need to manually select the correct port to program the TinyDuino. If no other COM# is showing up, you can try unplugging the Prusa device and using that port instead.

To test that a Micro USB cable had all the data wire connections necessary to use with an Arduino device, you would need to verify that the cable can transfer data. So testing the cable with a phone or camera that is able to transfer data, like pictures, would be a good test.

Additionally, an LED should come on and blink green (I believe this is the code that TinyDuino's ship with), and that would not help determine if the cable is correct. You could also plug in a battery while the TinyDuino is plugged in and an amber LED would light up to show that the battery is charging.

I hope that helps!

Awesome.  You're the best.  Ok, I tried a different cable, and lo and behold - it works!  The program even ran properly.  Thanks!
