TinyDuino / Re: Unable to upload sketch - Tiny Screen+
« Last post by Rick on October 08, 2019, 09:14:40 PM »
On Ubuntu, I was getting the "SAM-BA operation failed" error every time I uploaded (TinyZero) and would get port unavailable type errors if I tried to upload again within about 20 seconds. Similarly, once the sketch started running, serial communication would not work (port unavailable again) for about 20 seconds.

It looks like following the instructions in the link below seems to have fixed it.
https://linux-tips.com/t/prevent-modem-manager-to-capture-usb-serial-devices/284

I think the TinyCircuits processor presents itself as a modem and the OS immediately connects to it and tries to send it some modem commands unsuccessfully which prevents the Arduino IDE from communicating with it until the OS finally gives up. Maybe something similar is happening on Windows 7 as well. Here is another link with some background info.

-Réna,

Got it to work!!

Looks like SerialUSB is case sensitive...I was using a small-case "s" as in serialUSB...now with a large-case "S" as in SerialUSB it works...thanks again,

John

Hello jgavlik,

TinyScreen+'s should most definitely work with the SerialUSB command. It's likely that you need to download a board package in order to properly interface with your TinyScreen+. So that under the Tools tab you should be able to select your "Board:" as "TinyScreen+" and your "Port: " as "COMXX (TinyScreen+)"

Double-check the getting started tutorial here to make sure you have all the necessary software: https://learn.tinycircuits.com/Processors/TinyScreen+_Setup_Tutorial/

I hope that helps!

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

serialUSB.begin(9600);

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???

Hey Manfred!

Yes there is a program you can upload to loop the videos without seeing the titles of each video. The way it works, it will play all the videos in the order they're on the SD Card as soon as the processor switch is flipped to ON.

We'll be putting this program in a more permanent spot on our website in the future, but for now I attached it to this comment!

Cheers,

TinyDuino / Video player title
« Last post by Manfred on September 06, 2019, 09:30:46 PM »
Hi,
I’m not familiar with coding but was wondering if the video player could be set up to play a looping video without displaying any title? Currently it shows the headings on top of the video until a button is pressed.
Cheers,

No problem! Good luck with your project!

General Discussion / Addapting code when updating hardware.

Hi guys

I'm very new to Arduino. Long story short I've been working on a project using nRF8001 BLE shield to send 9AOF data to my phone, which works perfectly using the Example sketches in the tutorials. However I've decided to build a new version of this with the new BlueNRG-MS shield and obviously the code will need to be adapted.

As I'm so new to this I'm not actually sure how this might be done and would love any help or guidance to help me understand how i might go about this. 

Thanks

Excellent! That is super good news. I'm almost setup to test my integration of these wireless chargers now, so I'm very happy to hear that I can have more confidence that I'm not about to fry something.

Thanks for the response.
