If you look on the back of the board, there is a non-populated 16 pin SOIC footprint on the back with two surface mount resistors connecting pins across the footprint. We removed the resistors and put a MAX3232 on the SOIC footprint. This converts it to the RS-232 voltage version. We made a cable with power, TV, and DB9 hookups and connected this to the PC through a Sabrent USB/RS232 converter cables (which shows up in the device manager as a COM port) and it works. You can also build the level shifter (e.g. MAX 232 into the cable if you like.
It’s a JST PHR5 conector http://www.jst-mfg.com/product/pdf/eng/ePH.pdf. Available from Digikey, Mouser, the usual suspects.
I have acquired the image and have it in RAM: FF D8 …. FF D9. If I save it to the hard drive I can open it in Windows and view the image. I would like to convert the .jpg file to an array of pixels for image processing. Does anyone know of some C code I can use to do this?
Does anyone have the dimensions for the lens and plastic body? The manual only has the dimensions for the PCB.
No public wish lists :(
