#24221 Serial communication with FTDI Breakout Reloaded V1.1

Posted by hanzibal on 14 February 2012 - 07:52 AM

I assume you now get a response when pinging the device from MFDeploy? As you know, this is a reguirement for anything else to work.

I use a FTDI cable like this one:

This cable talks to the Netduino UART on a 3.3V TTL level and it always works very well for me. It is starting to sound as if your FTDI breakout board is broken.

Also, try a lower baud rate first. The higher the rate, the higher the likeliness of errors.

Furthermore, when serial is not working, always try swapping the cables, the question of wether TX or RX is the signal going in or out from where is always a matter of who's team you're playing for.

In analogy, according to the nazi's, Adolf was the good guy :rolleyes:


#15909 Wanna control your Netduino from a Smartphone?

Posted by hanzibal on 25 July 2011 - 09:23 PM

Hello all!

Just thought I'll mention that I've started a semi-related open source project for controlling various networked devices (such as the Netduino) using smartphones running Android, iOS or Windows.

The project is called iTachtoolkit and is available at CodePlex:

http://itachtoolkit.codeplex.com/

Here's a video of me controlling a LED triplet connected to a Netduino mini using an iPod touch:

Yeah, it's a pretty lousy video but it actually shows me using the iRuleAtHome app on an iPod touch controlling a Netduino via a "Netduino driver" that I wrote for the iTachtoolkit and then a Netduino mini running the ENC28J60 uIP-driver that I've previously ported to NETMF which is available from here:

Just imagine the things you can do using this combo. Please let me know if any of you are interested in the rest of the code and I'll supply that as well.

Best wishes!


#11119 Netduino + Sparkfun SD/MMC Reader

Good luck, your link is wrong though - this is what it looks like: http://http://www.sp...om/products/204 I guess it depends on what browser you are using, but it doesn't work on my iPhone running Safari.


#11081 Networked music player using the mini

Posted by hanzibal on 18 March 2011 - 04:43 PM

Mario, yes all C#. It even plays 192 kbps smoothly, though actual speed is probably less in average due to vbr. Told you I'm a software guy :)


#11045 Networked music player using the mini

Posted by hanzibal on 17 March 2011 - 07:39 PM

Hi there! My project is about creating a networked music player using the Netduino mini and a vs1053 mp3 decoder chip. I know there are lots of streming music players out there alyready and even though I got some special plans for my little baby, I'm mostly doing this for the pleasure of it. Currently, I'm kinda concept proofing, but it's going pretty well. Got the mini hooked up to a vs1053 breakout board from Sparkfun (rectified version), SD card, a pushable rotary encoder and a class D amplifier chip from Texas connected to a pair of monitor speakers. The latter is merely for sound quality testing and playing my favourite tunes while working with the project :) Anyway, attached is an image of how it all currently looks. Topmost is the 2x25W @ 4 ohm class D amplifier board based on the TPA3123 from TI which is pretty much a T-amp. Below that is my breadboard and from left to right, the black rotary to adjust volume and skipping forward through songs (mp3, wma, AAC, Flac, waw, MIDI, PCM and Ogg Vorbis, etc). Then there's the VLSI vs1053 digital music decoder bob, the Netduino mini of course and the SD. I think the Netduino and NETMF really rocks as a means of prototyping and the vs1053 is one bad boy when it comes to audio. As you can see for your selves, my girl ain't pretty, but boy can she can play B) My next major step will be to add TCP/IP networking using a MRF24WB0MB radio tranceiver from Microchip. I should probably start with a wire bound Wiznet, but I'll give it a try first. Best wishes, all!
