Pixel_Sum Address: 0x07 Access: Read Reset Value: 0x00 Bit 7 6 5 4 3 2 1 0 Field PS7 PS6 PS5 PS4 PS3 PS2 PS1 PS0 Data Type: Upper 8 bits of a 15-bit unsigned integer. USAGE: This register is used to find the average pixel value. It reports the upper 8 bits of a 15-bit unsigned integer, which sums all 324 pixels in the current frame. It may be described as the full sum divided by 128. The formula to calculate the average pixel value is as below: Average Pixel = Register Value x 128 / 324= Pixel_Sum x 0.395 The maximum register value is 159 (63 x 324 / 128 truncated to an integer). The minimum is 0. The pixel sum value may vary from frame to frame. Pixel Data Address: 0x08 Access: Read/Write Reset Value: 0x00 Bit 7 6 5 4 3 2 1 0 Field SOF Data_Valid PD5 PD4 PD3 PD2 PD1 PD0 Data Type: Two status bits, six bit pixel data. USAGE: Digital Pixel data. Minimum value = 0, maximum value = 63. Any writes to this register resets the pixel hardware so that the next read from the Pixel Data register will read pixel #1 and the StartOfFrame bit will be set. Subsequent reads will auto increment the pixel number. To dump a complete image, set the LED to forced awake mode, write anything to this register, then read 324 times where the DataValid bit is set. On the 325th read, the StartOfFrame bit will be set indicating that we have completed one frame of pixels and are starting back at pixel 1. It takes at least 324 frames to complete an image as we can only read 1 pixel per frame. The pixel hardware is armed with any read or write to the Pixel Data register and will output pixel data from the next available frame. So, if you were to write the Pixel Data register, wait 5 seconds then read the Pixel Data register; the reported pixel data was from 5 seconds ago. Field Name Description SOF Start of Frame 0 = Not start of frame 1 = Current pixel is number 1, start of frame Data_Valid There is valid data in the frame grabber PD5 –PD0 Six bit pixel data
