Embracing Linux for Good

Saturday, April 14, 2012
Tag : ,
We have been struggling lately with Windows XP operating system. Unfortunately we were unable to switch to Linux since long. However we tried to use the virtual machine available for Ubuntu. Recently we procured a 1TB portable hard disk and were able to back up the windows entire system. Finally we installed the recent version of Ubuntu 11.10
Now we have completely transitioned to Linux and done with our support troubles with Microsoft and thence related.
This means we would be posting more tips and tricks for Linux including tutorials and Problem walk throughs.


We were avid fans of Gadgetfactory and now we have more reason to celebrate!!
ZPUino 1.0 Released
The release of ZPUino marks a step worthy of historical mention in soft-core processors. The existing hardware such as the Papilio One and SE3 boards are supported by this remarkably fast processor.

We have already tired this with the Papilio One 250k board and have been successful in executing Serial as well as GPIO control. All in Arduino Style.
The best part of this soft-core processor is that it has an Arduino IDE specially made.
All Functions are nearly the same as Arduino but since the core runs at 100MHz-96MHz you can expect much more number crunching capability.

Here is a Document that Details the ZPUino Processor[PDF]:

We have a step by step procedure for using the ZPUino running on Papilio One 250k on Windows:

1. Download the Following

2. Install the Papilio Loader and Flash the Papilio Board
3. Now unzip the ZPUino IDE to the desired folder. For linux users you might need to locate the ID and the tool chain separately. We tried it out on a windows PC as the Papilio loader is not readily available as linux executable form.
4. Open the IDE and write your desired program. Example:
void setup()
{
  Serial.begin(9600);
  pinMode(13,OUTPUT);
  Serial.print("Start");
}

void loop()
{
  digitalWrite(13,HIGH);
  delay(1000);
  digitalWrite(13,LOW);
  delay(1000);
  Serial.print("S");
}

5. Now configure your Arduino IDE to show the desired board (Tools->Board->->Papilio One 250k) and Serial Port to the correct one. Yes there might be a confusion on the Serial port side but you can try the two you see. For Linux also you would be able to see the /dev/ttyUSB0 and /dev/ttyUSB1 so you need to select the correct one. Or just to trial and error.
6. Hit 'Upload' button - Thats all
