Subject: [Emc-users] RPI4 spi interface Mesa 7Cxx cards
I am trying to familiarize my self the 7C80 and 7C81 cards. I have
multiple projects for them. a couple of lathes, an update to a minimill
currently running parallel port. And enhancing my Skyfire P2 with 4th
and 5th Axis and Highspeed spindle. The Skyfire is currently running
parallel port to 7I76 and probably be able to handle the changes but, I
want a testbed before I make the changes and to exercise the drivers and
their programming. Once I start the mods I don't want to be down and
extended period of time.
On the lathes I will initially do the mini first to learn before growing
to the 14" x 40".
I currently have the pi4 4G the latest raspbian converted with RT-Prempt
but now I need to configure and use mesaflash. halcmd and halrun work
but I get errors with hm2_spi.
for a RPI, you should use hm2_rpspi
man hm2_rpspi
I can't seem to find the starting place. Please provide some hints.
Hubert
