Take a look at my sample Machinekit configs for Furaday Cape for BeagleBone. You can download them following a link at the end of the product page: http://www.robotise.lt/hardware-for-beaglebone/8-furaday-cape-1-2.html I am using PWM and DIR on many machines already. By the way these are not

[Machinekit] Decent latency results on a cheap old computer

2017-01-06 Thread Fernando Correa Neto
Hey there Just wanted to share some findings after combining all sorts of "good practices" for getting a decent MachineKit setup. The machine is dated and uses a CPU than can be bought for less than a dollar I think. The TL;DR is: Servo thread at 15052 Base thread at 12569 Details: OS: Debian J

Hi Yes there is plenty of old hardware out there that works well and at a fraction of the cost of even a BBB, let alone the cape etc. I am still using a single core P4 in my workshop that returns a rock sold 9K max jitter on base thread, using a home brew rtai k

Okay the direction issue may be solved with pwmgen type 1 (which is discussed in another post from me) so it is not important in this post. The Index signal issue in the other hand may be because of electrical interferences (i have to look for that) Am Sonntag, 6. November 2016 16:33:46 UTC+1 s

Is "pwmgen.0.dir" the correct name for machinekit? because it says "pin ´pwmgen.0.dir´ is not writable" i have written the line above all "hpg.pwmgen" lines (if that is what you ment) is combining "hpg.pwmgen..." and "pwmgen" possible or do i have to choose one? Am Freitag, 6. Januar

Hi, The eQEP encoder is currently broken for me, it certainly used to work but now it is very erratic, I’ve just changed over to using the hal_pru_generic encoder which luckily can be made to work using the same physical pins as eQEP0 and it seems to have solved my issues. I do intend to trac
