I'm no electronics expert... The datasheet for my single ended encoder > says max 30 mA, so I figured 220 ohm at 3.3volts gives max 15mA or so... That would be the current handling ability of the encoder's outputs, but all you have to do is drive an FPGA pin. That takes almost no current to do. Since you want to make sure that that FPGA pin has a defined state when it's not being driven you need to pull it toward one side with a resistor. If you use a strong pullup/down it requires more current to drive it toward the other side. The 15mA is being wasted through that resistor. 15mA isn't a big deal but if you have alot of I/O it'll add up. If your FULL error message is: > It literally just prints out "segmentation fault". I just tried it on one of my other Linuxcnc machines and if LinuxCNC is running, I can open a new terminal and cd to the halshow.tcl directory and ./ to execute it just as if I started it in the GUI. That doesn't work on this image even after using the export command you mentioned. I'll have to try updating the packages you mentioned and see if that helps. I'm still trying to find some info on some of the "tags" used in the hm2 vhd files, I don't suppose this is documeted somewhere? I see the "capsense" tags but I'm not sure what that is, something Cramps related? Some of the Mesa PWM implementations are a 3 pin deal with an enable and direction pin. The MK configs only seem to use the "PWMAOutPin" per unit. Looking at a top level vhd file it appears that the PWMBDirPin, and PWMCEnaPin are there. I suppose it's just a matter of including these pins in that unit? There is a NANOADCTag listed in the ModuleIDs but I haven't found any usage of it other than that. Is that just a placeholder or does it have an implementation? -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
