1  Using Arduino / Microcontrollers / Re: Is It Possible to Burn the Bootloader of a Pro Mini with a Nano? on: August 28, 2014, 02:43:47 pm
Yes, you can use your Nano as programmer.
Just load the ArduinoISP  sketch to it

With it, in the case you cite, the master would need two USARTs (or software equivalents) one to communicate with each slave.

Not necessarily
The Frsky telemetry I mentioned is using one bi-directional data line (rs232 - TTL level) at 57600 baud to communicate with several slaves. The slaves have an unique ID, I belive at the moment there are 28 Slave ID's defined.
FrSky call it Smart Port.

So at one end (the receiver in the plane) the receiver is the master with x number of slaves.
One the other end (the transmitter on the ground) the transmitter is the master with x number of slaves

The good thing is that it is open source (OpenXSensor, OpenTx)

For an example, maybe a telemetry package for an RC airplane, where each of those modules are different sensors (gyro, pressure altimeter, airspeed sensor, etc...)

That is in fact the way that FrSky telemetry is working.
It use a serial connection, and each sensor has a unique ID, f.ex. ALT for altimeter.
The receiver then polls each sensor for a value one at a time and send the data back to the transmitter on the ground.
On the transmitter there is a voice modul, so the values can be read out loud (you can't read and fly at the same time !)

This might help.

5  Using Arduino / Interfacing w/ Software on the Computer / Re: Android communication over Bluetooth on: August 24, 2014, 02:45:10 pm
Thanks for the clarification shev.

It sounds like an exciting project.
However, I have a problem
When I run your app on my phone and try to connect to my Arduino / bluetooth it makes a connection, but imidietly disconnect again.

I know that my setup works because if I use any other bluetooth app on the phone there is no problem.

Edit:
My bad, I used the hardware serial, instead of pin 2 and 3.
Now it works.

It do not need any permissions. That's the messages I get when downloading.
I don't know if that's what you mean. Normally I don't pay much attention to these messages when downloading apps, maybe I should in the future.

You are welcome.

I am not sure how this is working.

I tried making a new project in the editor.
I get the files to use with arduino, works OK.

But when i click on the "Download android application"  (on my phone) I am redirected to the Android play shop, where I can download the RemoteXY app.

But this app just does nothing, and are certainly not the app that I made in the editor:

Are you sure you are using the right pin ?

check this line 165-175

Actually there are many options for debugging code on the Attiny85

http://www.ernstc.dk/arduino/tinycom.html

I use TinyISP and Tinyknockbang. It is very easy to use, it use on of the programming lines to communicate with the tiny.

You could try this. It uses a SN754410 as driver

CD - motors are usually BLDC motors:

You will need an ESC  like this to control it

'make' is not recognized as an internal or external command,

That seems to indicate that you don't have make installed.

The files should be in a folder called PinChangeInt (same name as the .h file) in your library folder
