USB Hacking to MIDI Out 5 Dins Keyboard

[masreg]

I am a totally newbie and keen to learn.

Based on "Collin's Lab USB Hacking with Arduino" video dated November 30th, 2010, I am really inspired to build this device. But some of the parts have discontinued.

http://www.youtube.com/watch?v=kfCDjwHBBuM

#1. The USB host shield has been discontinued - http://www.circuitsathome.com/products- ... r-arduino/. So I have to get the current replacement - USB host shield v2.0 - http://www.circuitsathome.com/products- ... assembled/. It will also require an Arduino Uno board as the micro controller.

After reading your product specification, May I use Freetronics USBDroid (with USB host built-in) by Freetronics http://www.freetronics.com/products/usb ... 7Yn-I2SxD0 for this project?

#2. I downloaded the sketch code http://cdn.makezine.com/make/2010/12/LP ... 01203a.zip and paste it to latest Arduino IDE v1.0.5 under OS X and clicked "verify". There was an error on line

Code: Select all

EP_RECORD ep_record[ LPK25_NUM_EP ];  //endpoint record structure for the LPK25 controller

the error message said

Code: Select all

"EP_RECORD" does not name a type.

Note: In this scenario, I do not have any Arduino board yet (But I'm planning to get one), I have installed Arduino IDE software. Where did I go wrong? See below:



#3 I notice the file extension of latest Arduino v1.0.5 is .ino. The sketch file suffix downloaded above is .pde. Am I downloading the right file? Does Arduino IDE changed user's sketch file extension lately?

Any guidance/explanation would be much appreciated to plan this project properly.

Thank you.

Grumpy_Mike mentioned the latest USB shield R3 with more devices support.

Game controllers: Sony PS3, Nintendo Wii, Xbox360.
USB to serial converters: FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers.
ADK-capable Android phones and tables.
Digital cameras: Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP.
Mass storage devices, such as USB sticks, memory card readers, external hard drives.
Bluetooth dongles.

Does Freetronics USBDroid http://www.freetronics.com/products/usb ... 7Yn-I2SxD0 sufficient for USB Hacking -> MIDI Out task?

Isn't the compatibility factor based on the code we write?

It comes down to the code, both the Arduino USB host shield and the USBDroid use the same MAX3421 USB host controller IC.

Hi John, I found a sketch file that close to what I need.

I followed its header instructions, I have copy-pasted the legacy USB host library and I used Arduino IDE version 0023 software. The error compiling is below:

Are you able to help where I went wrong?
