I think it is because i have not connected the Arduino is it? As far as i can see, all Pins are outputs, can i set them to input via config-pin or do i have to change the file and compile again? The arduino has to be connected, with the .ino script flashed to it and running AND the port must be correct The serialreceive.comp has the port defined as #define DEVICE "/dev/ttyACM0" That was correct for the type of arduino I used, but others will use /dev/ttyUSB0 etc You need to program your arduino with the counterpart script, note the port it appears on and change serialreceive.comp to match, then recompile that. THEN you hopefully get somewhere :) anyways thank you Am Sonntag, 2.

Thought it sounded familiar. I wrote that 5 or more years ago, just to demonstrate passing a bunch of pin values Arduino / HAL component It does not really do much and would need changing for the specifics of whatever you want to do. > > i do > > cd /home/machinekit/Desktop > > sudo comp --install serialreceive.comp > > <SNIP> > > so i added "loadrt serialreceive" to my hal file and when i start my > machine it gives me an error: It is a userspace component, use loadusr > > > CRAMPS.hal:23: insmod failed, returned -1: > do_load_cmd: dlopen: serialreceive.so: cannot open shared object file: > No such file or directory There is no serialreceive.so, it is an ELF binary userspace file, so it will be in /usr/bin. Needs to be loaded with `loadusr -W serialreceive` from a suitable point near the end of your hal file. -- 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.
