OTCDDK

OTCDDK means "Other Tone Core DSP Development Kit". It was enginered in order to permit develop DSP algorithms in other platforms such linux or Windows.

Install and run on Windows

1. install git
2. if you want to compile dsp codes:
   1. download "make" from "https://sourceforge.net/projects/ezwinports/files/"
   2. install "make" - downloaded above - into git mingw directory (mine is under C:\Program Files\Git\mingw32)
3. clone https://github.com/hgamal/OTCDDK.git
4. start git bash session under cloned directory

Installing WinUSB

In order to make tcddk-ctl work, the Tone COre Developer Line6 Interface must to be associated to Microsoft Winusb.sys. The follow these instructions to load the driver:

1. Plug in your device to the host system
2. Open Device Manager and locate the device
3. Right-click the device and select "Update driver software"
4. from the context menu. In the wizard, select "Browse my computer" for driver software
5. Select "Let me pick from a list of device drivers on my computer"
6. From the list of device classes, select "Universal Serial Bus devices"
7. The wizard displays WinUsb Device. Select it to load the driver.
