  1. Hi all, I'm trying to connect a MIPI camera (Rpi camera v2) to the Digilent Nexys-4 DDR board through the JXADC connector. Since these pins are routed for differential signaling, the JXADC connector seemed the best option for this, but I soon ran into a couple of problems though: - the JXADC pins are not connected to any clock input pins on the Artix-7, so I get placement errors when trying to connect the MIPI clock lane to these pins. I found out there is only 1 P-version clock input pin available on all the PMODs, namely JB10 (which connects to H16 on the Artix-7), so I trie
  2. Hi all, I m a beginner in FPGA(zync 7000). I want to implement a project which took images from two cameras, one with usb(uvc) interface and one with csi-2 interface. One thing to note that i not using both cameras simultaneously. Only once at a time(Switch over whenever required) With first USB camera, i want to do some image proseesing functions like filtering and CLAHE(Contrast-limited adaptive histogram equalization) on the captured image. Then the processed is images is displayed on a HDMI or RGB interface mini projector(DLP 2000). Here i indicated both HDMI
  3. Hi all, I have a Zybo and have been using it successfully for a variety of HDMI / VGA video projects. I'd like to have a go at interfacing a Raspberry Pi V2 camera. I understand that I need to implement a MIPI CSI-2 receiver in VHDL and I have a reasonable idea of how to proceed. This may take a bit of effort, but that's part of the fun! However, what I'm not sure about is whether I can specify the appropriate 1.2v IO Standard that's required on the Zybo board via the high speed PMOD ports? Or, will I need to buy one of the newer Zybo-Z7 boards? I realise that the newe
  4. I'm trying to understand how to set up clocks and read data from a MIPI camera sensor. The sensor (Omnivision 5647) uses the MIPI CSI-2 protocol with D-PHY for the physical layer. The stage I am trying to get to is to be able to observer SoT (Start of Transmission) signals after which I can start parsing the CSI-2 protocol packets. In a small MIPI writeup located at http://archive.eetasia.com/www.eetasia.com/ART_8800715969_499489_TA_a466fca2_3.HTM there are 2 statements that are to be taken into consideration when trying to read data: "The high speed payload data from the transmitter i
