But this may be all academic at this point. I think that even if I get the file loaded with BSPIs the stuff that I will need to figure out to make this all work seems difficult and may not be worth the time. So what I _really_ wanted is a simple SPI interface to send current command to my drives, which I thought would be simple to do, however, now I think I should just use a bit file that was intended to work with a card like the 7i33. So I found something that I like called 7i80hd_25_svua8_4. I think this is for a 7i33 but it also has some UARTs as well. I would like to make use of the UARTs for non-realtime communications with some of my devices such as SICK hiperface encoders to read the absolute position and or maybe communications with some of my drives. Instead of using the SPI passing simple current_magnituce to the drive I will just use the PWM output as the current command like an analog servo in torque (current) mode. If that really all does work I feel like I may be more competent hacking the VHDL code for the FPGA to add my own SPIs that just look like the PWM registers to LinuxCNC. When I had a real job I used Altera (now Intel) Quartus with SOC (dual ARM with FPGA) so using the Xilinx stuff does not seem as challenging as linuxCNC code. but when I load the 7i80hd_25_svua8_4 and then run my simple hal file using halrun I get a different error hm2/hm2_7i80.0: inconsistent Module Descriptor for UART Transmit Channel, not loading driver. so, do I need to load something like mesa_uart first? that does not appear in the list of 2.8 or 2.7 man pages so I suspect I need to do something different but a lot of the 2.8 man pages are missing - so this is really getting hard fo figure out regards, John _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
