    Pcam 5C hummingboard

    Hi @Maxim, Here is the PCAM 5C resource center that has the reference manual, a link to the OV5640 datasheet, schematic and a demo with the Zybo-Z7-20. We haven't not used the PCAM 5C with the Hummingboard. Here is a SolidRun forum thread that discusses using the OV5640 Module with the hummingboard that should be helpful for your project. thank you, Jon

    QSPI Program Load is Slow

    Hi, I suspect you're using slow default options for bitstream generation. Increase the clock rate and enable bitstream compression. It should be much faster.

    How to read from SD card on ZYBO

    hi @Notarobot, i'm sorry if I didn't make sense. The problem that I was facing was that the contents of text file (generated by MATLAB) that I was trying to read from SD card had numeric data. whenever I read the data from SD card It got converted into ASCII in read buffer, whereas I wanted decimal values in the buffer so that I can store them into memory. but if I somehow converted my textfile contents into Unicode (the format that xil_write generates in output file), PS would read them perfectly as decimal numbers. I was unable to convert my file contents into that format since data were separated by commas and the data was very big. I found the solution to my problem, I simply have MATLAB to convert the decimal number in array to Unicode and then output them to a txt file without including commas b/w values. using following command lines X_uni=native2unicode(X_deci); dlmwrite('r.txt',X_uni,'delimiter',''); Thank you for your concern.
