Parallax releases a FPGA emulator for its 8 cog Propeller

Gareth's picture

Parallax inc. have released FPGA code that allows a number of develompent boards to emulate the Propeller 8 cog parallel chip.

Above is my converted Deo Nano ..... the Green Led0 means system is running on cog 0

Yes each LED is an indication of running cogs (that in itsself is a help for programming, ie knowing how many more parallel processes can be run)

Upgrading the Raspberry Pi camera..

Although the stock lens is sharp ..... it lacks that spycam aspect.......

There are loads of fixed lenses out there ... however nothing beats a good zoom lens.

I have been searching for a while to find a way to control my projects with "Muscle" activity , at last I have found an easy solution with this :- an Olimex EKG/EMG shield from Newark Electronic components .

Raspberry PiNoir settings and what to expect....

A picture is worth a 1000 words.  (for this experiment all pictures are 640x512)

This is a Picture Out Of The Box ..

Here I have documented some of the capabilities of the PiNoIR Infra red Camera.

Raspberry Pi - first Pictures ----

I have just received a Pi NOIR (Raspberry flavored) from the UK firm

Above is a picture taken using a 3Watt Infra Red LED in pitch darkness.

Propeller MRLComm.spin code name GroGoProP

Gareth's picture

Here I present a Program to clone a Parallax Propeller into thinking its an Arduino for use with MyRobotLab.

Its just a first Proof of concept with basic MRLComm commands

I devised the code to emulate an Arduino Uno :-

  1. Digital Inputs
  2. Digital Outputs
  3. Analog inputs
  4. Servo Outputs pin orientated  (still needs tweeking)

It already can be used "as is" however there are many commands to be shoehorned in.
