Hi,
I have no experience with c++ on the bbb, but for C, I had to
put the fftw libraries into /usr/local/include so that they could be found.
BTW I have also tried to connect a LTC2500-32 ADC to a BBB SPI master
and I lost so much time over it that I programmed the existing Xilinx
Coolrunner2 to receive the SPI at 100 MHz and now I read them via
R30/31 of PRU1 bytewise. Getting all 32 bits takes 110 ns including
shifting & rebuilding the int32.
regards, Gerhard

Hi guys,
I need your help, the situation is the follows:
I need to set up the beagle bone as SPI slave for reading data of a
sensor, and since the kernel GPIO functions do not support very high
frequencies I need to do that using the PRU. I am developing my
application in C++ and I found this link which seems to be what I
want: https://github.com/giuliomoro/bb-pru-spi-duplex
However, I got stuck from the very beginning; for what I've read, I
have to install the prussdrv library by hand, I download it here:
https://github.com/beagleboard/am335x_pru_package and follow the steps
mentioned here: http://mythopoeic.org/bbb-pru-minimal/ (section
"Development tools"). After getting the library at "/usr/include" the
C++ application can't still find it.
Anyone can give me a tip about what am I doing wrong?
Best regards,
Fred Gomes
