Good morning Gerhard, Thank you very much for your response,
I did that but surprisingly when I try to include the library in my C++ application it can't find the libraries, although they are in the correct folders (namely "usr/lib" and "usr/include"). O followed the steps mentioned here: https://www.npmjs.com/package/pru#driver-library-and-assembler in the "Driver and assembler" section this time, but it still kept not working. Did you find any different from what you've done there? Or rather have any inkling for what I may be doing wrong? Thank you very much, --Fred Gomes Gerhard Hoffmann <[email protected]> escreveu no dia segunda, 22/10/2018 à(s) 22:28: > 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.
