1. 5-pin header to connect directly to Freescale Line Scan Camera
2. Header for 2nd linescan camera (optional)
3. RCA Camera Interface. Includes an LMH1981 Sync Extraction chip and connectors to MCU to allow for low resolution (32x32) decoding of signals
Supports forward, reverse and braking.
Schematics (Sent to MyRO on 4.4.2012) - Includes 3d view
Assembly Prints (For Reference)

This code works with Rev B of the board (and Rev A). All major interfaces & peripherals have been tested. At some point we will make a video going through the code. By default the Linescan camera code is enabled. The code in Main.c is pretty easy to follow. There is also code for the NTSC camera but must enabled in the TFC_Config.h file via a pre-processor directive.
There is also code used for teh OSTAG interface, Labview demo applications and drivers for the USB
Just verified the OSJTAG. Test Project to blink the battery LED's was downloaded into the K20
Testing the Servo circuits…..
Testing the pots, servos, H-bridges and K20 USB port
Linescan Camera Bringup with Labview
NTSC Camera Bringup with Labview
1.) This is a basic demo of an NTSC camera being brought in using the a Combo of the ADC, port interrupts and DMA transfers.
2.) I *ahem* overclock the ADC to 24MHz to get some extra resolution for a 64x64 pixel image (the first 6 columns are junk as they contain color burst data*)
3.) I decimate the images to a few frames per second to send over the WIFI (the booster pack card I made) to a Labview program. The Kinetis can bring the data in a the same frame rate of the camera, I just need to send much slower as there is some overhead in my communications scheme (ASCII text) and the WIFI is driven via a UART.
4.) In reality, I can get a 64 x 480 pixel image in memory as I pull in all the lines. I just decimate the rows to get a 64x64 result on the labview display.
5.) DMA does most of the work freeing up the CPU to do algorithms in the foreground.
