| sudip | hi, I just built the cluster-demo and running it on qemu. Instead of the animation I will like to use cansend to send signals to control the cluster. Can anyone please point me to any documentation for that.. | 17:41 |

| smurray | sudip: sorry, I never got around to documenting that. Look at the AGL.conf file that meta-agl-cluster-demo/recipes-config/cluster-dashboard-demo-config/cluster-dashboard-demo-config_1.0.bb installs | 19:33 |
| smurray | sudip: if you run aglsetup.sh with "agl-cluster-demo agl-cluster-demo-preload", that recipe gets enabled and the conf file installed to disable the animation and use CAN | 19:34 |
| smurray | sudip: note that the CAN messages used are specific to the agl-vcar definition in the CAN binding, it doesn't use OBD-II diagnostic messages for it | 19:35 |
| sudip | thanks smurray, I was only trying with agl-cluster-demo. I am planning to send signals using vcan and cansend for now | 19:36 |
| sudip | will try agl-cluster-demo-preload now | 19:36 |
| smurray | sudip: you can copy over the AGL.conf or create it by hand if you already have an image, just need to make sure it's /etc/xdg/AGL.conf and "chsmack -a _" it so it'll be readable | 19:53 |
| smurray | sudip: you can grab the recipes-demo/simple-can-simulator/files/simple_can_simulator.py script from meta-agl-demo if you need something to drive it, easier than doing cansend | 19:54 |
| smurray | sudip: that script's easy to hack on as well | 19:55 |
| smurray | sudip: for the steering wheel events, I have a test script here somewhere that does cansend for all of them, but simple_can_simulator.py simulates the cruise control ones | 19:57 |
| sudip | smurray: thanks. before asking here I modified the image to add a patch to make 'runAnimation' false which stopped the animation but I was struggling to send the signals | 19:57 |

| sudip | smurray: I am definitely missing something. After adding AGL.conf, now the simulation has stopped and I am running 'simple_can_simulator.py -v vcan0' which shows its sending the speed data but I am not seeing any change in the cluster. | 21:08 |
| sudip | I am setting up vcan0 with - https://psty.io/p?q=244bc | 21:09 |
| smurray | sudip: that's not going to work unless you've configured vcan0 as the interface for the CAN binding to use in /etc/dev-mapping.conf | 21:09 |
| sudip | ahhh.. right.. its using can0 | 21:10 |
| sudip | thanks again | 21:10 |
| * sudip tries | 21:10 | |
| smurray | sudip: and it's not going to work if you bring the interface up by hand from the command-line after the CAN binding starts, you'd have to restart the whole chain (CAN binding, signal-composer, dashboard) | 21:10 |
| smurray | sudip: probably simplify your life if you port this change to the cluster demo: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl-telematics-demo/+/25577 | 21:12 |
| smurray | sudip: that would bring the vcan interface up automatically on boot | 21:12 |
| smurray | sudip: I'd never thought anyone would use these demos w/o CAN hardware, guess that was naive | 21:13 |
| sudip | smurray: I am just trying send an input to agl-cluster-demo-dashboard and I think using CAN signals will be the easiest. Not sure if it is even possible to use fifo or msgq with qml | 21:19 |
| sudip | and thanks for the pointer to the patch, I was just thinking of adding a script to bringup the interface after networking is configured | 21:20 |
| smurray | sudip: architecturally the place to stick a non-CAN transport in would likely be in a new binding or maybe a plugin to the signal-composer binding, but that'd take some work | 21:22 |
| sudip | smurray: I assumed it will take some work so started looking at how to use CAN with the demo | 21:28 |
| smurray | sudip: it's definitely the least effort approach | 21:32 |
| sudip | smurray: thanks for all the help, and sorry to spoil your Sunday evening | 21:34 |
| smurray | sudip: no worries, still afternoon here ;) | 21:34 |
