• Manufacturer Part Number: Chameleon-PIC
• Description: MCU, MPU & DSP Development Tools PIC24 & PROPELLER DEV SYSTEM (SBC)
• Manufacturer: Nurve Networks

Specifications of Chameleon-PIC

• Processor To Be Evaluated: PIC24
• Data Bus Width: 16 bit
• Interface Type: USB, VGA, PS/2, I2C, ISP, SPI
• Operating Supply Voltage: 3.3 V, 5 V
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The final step is to release the Chameleon PIC from reset (which will also release the Propeller as well since the resets
are the same). You can do this by either unplugging the PICkit 2 programmer or more easily press the “Bring target
MCLR to VDD” (7) toolbar button. Now plug your Chameleon PIC into your NTSC television and VGA monitor and verify
your screen looks similar to Figure 15.46
If you are having difficulties getting your Chameleon PIC to program properly or video is not displaying, you may try the
suggestions below:

15.1.4.2 Enabling Compiler Optimizations
Before we finish I wanted to mention how to enable/disable compiler optimizations. Remember, after 60 days of use with
the student edition of the MPLAB C compiler for PIC24s, optimization level 0 and 1 can only be enabled. Still level 1
compiles significantly faster and smaller code than level 0.
To change the optimization levels first start by opening the project options (ProjectBuild OptionsProject). Next click on
the MPLAB C30 tab as highlighted in the green box in Figure 15.47.

Is your PICkit 2 programmer plugged into the USB port and enumerated properly? The first indicator is whether or
not the green power LED is lit on the PICkit 2. Additional error messages may also be displayed in the output
window.
Is the Chameleon PIC powered from a 9-12V DC or USB cable power source and turned ON?
Is the Audio/Video cables plugged into your television and the Chameleon PIC properly. Make sure video is
connected to video and audio to audio.
If all else fails, first try to restart MPLAB, save your workspace and project first! If it still does not work try
rebooting your computer.
