Greetings fellow travelers on the road to running machinery with an r-pi; That part I seem to have more or less under control, and whats left is a matter of carving up the hal file, and finishing the encoder, at which point its more a matter of keeping swarf out of places it doesn't need to access than any huge technical problems (famous last words...).
So, lets talk display facilities for this beast. I have an Orange Pi + 2E, and the folks on the armbian forun have convince me to give the legacy version of the armbian build a shot. Now, both of these boards have a wifi facility, and one ethernet port only. So I am proposing, and you folks can shoot me down, to: 1. make both boards part of my local network, the r-pi is already. 2. use the O-Pi for the x-renderer by setting up the wifi connection between the two such that the R-Pi is slaved to the O-Pi, and the x data is sent back to the O-Pi over this wifi connection, which AIUI is faster than the ethernet. Use a totally unencrypted connection between the two as they will be perhaps 6 to 9" apart in a closed steel box which should fairly well shield them from any interference from the neighbors and vice versa. I did manage to find the wifi page in the Chinese OS the O-Pi boots to when it can't find a bootable u-sd card, and its longer antenna makes it an excellent band scanner in that it can at least see the BSID of several neighbors routers, and actually displays it in English. The antenna on the R-Pi is much smaller and I have not installed the packages that will enable its wifi yet, so thats one of the bits of info I need since I do have a wifi, but its restricted to matching MAC addresses before it connects.. So the monitor/keyboard/mouse will be connected to the O-Pi, the two will be linked by the wifi, so that the R-Pi takes orders from the O-Pi's keyboard, and the x data from running linuxcnc -l on the R-Pi will come back to the O-Pi over the wifi link and be rendered and displayed on the O-Pi's monitor. This will no doubt involve two different local 192.168.xx.nn network setups. Have any of you done that, or am I walking on unplowed ground and doomed to fail? Thanks everybody.
