In the documentation for BSPI at http://linuxcnc.org/docs/2.8/html/man/man9/hostmot2.9.html#BSPI there is a reference to some man pages like man mesa_7i65, which prints the man page when I issue the command for it, But the documentation also refers to some other man pages for the the following: man hm2_bspi_setup_chan, man hm2_bspi_write_chan, man hm2_tram_add_bspi_frame, man hm2_allocate_bspi_tram, man hm2_bspi_set_read_funtion and man hm2_bspi_set_write_function for the exported functions.
I see that these functions are called in the Mesa 7i65 component that Andy Pugh sent me a while back https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/drivers/mesa_7i65.comp My questions follow: *1) what must I do to see these bspi man pages?* *2) what does "exported function" mean in the context above?* *3) in the 7i65 component there are some lines that refer to RTAPI but in my case I am planning on using the PREEMPT RT enabled kernel. Does the component work with either?* My goal is to create a sub driver component to send and receive data via one or 2 of the SPI channels that are available for one of the FPGA bit files such as 7i80hd_25_svsp8_6_7i46.bit I have asked about this in the past, but now I am really ready to make things work. I have hardware in hand.
