@scanner_darkly , thanks!! That first link you provided is great, the comments help a lot!! I’ll be looking at both of these the next couple days

@jasper_ryder , I definitely can’t promise anything but I’ll see what I can do :slightly_smiling_face: if I’m unsuccessful and enough people want it I’m sure we can look for community development

So I started a Hello World program by modifying the ansible_arc.c file, I’ve uploaded my code here:

Unfortunately I hit some snags when compiling


Do I have to declare the functions I’m adding in another file besides ansible_arc.c?
Maybe I’m biting off a bit more than I can chew here.

#10

I’ll maybe have some more time this week to look into this a little more
@scanner_darkly would you have any advice on how to proceed?

#11

sorry, was away, having a look now.

you do need to declare functions in either ansible_arc.h (or if you declare in ansible_arc.c do it before they are called or assigned). i tried a quick fix but there are other valid compilation errors - where do you define mArcLevels? that should go to main.h (see where mArcLevels is defined).

a good way to approach this might be making smaller changes and then trying to compile after each step.

I’ll declare my functions in ansible_arc.h and maybe see what is unnecessary of my code and delete that, incrementing slowly, thanks!

#13

this is kind of a tangent, but it would be really awesome if the Ansible firmware was structured a little more flexibly so that additional apps could be added, but as it is, its sort of hard-coded for two apps in either hardware mode.

#14

Is it? Taking a look at the code where it switches modes it looks to just be calling a case

What I attempted to do was to add another case

I’m not actually sure if this will work/ if it’s proper

#15

ah… maybe its not as hard-coded as i thought… i guess what would be really killer is if there was like a boilerplate template for a grid or arc app on ansible that lived in its own .c/.h files and you could just start modding it to begin building your own app.

That would be really nice!

#17

i don’t think there is a specific limitation on number of apps, it’s just a matter of adding all the appropriate handlers, grid press/encoder rotation processing and LED rendering. a boilerplate template would be great! (would love to do it if i had the time).

So I’ve worked on it a bit more and I’ve gotten less compile errors with quite a bit of clean up


If anyone else wants to jump in at this point to help development that would be greatly appreciated, I’ve uploaded my changed files here: https://github.com/acbakhit/AnsibleArcHelloWorld

#19

you need to declare hello_state structure in ansible_arc.h and uncomment https://github.com/acbakhit/AnsibleArcHelloWorld/blob/master/main.h#L56

it’s basically a structure that should hold any state variables you want to persist in flash (including presets). take a look at levels_state_t and cycles_state_t as an example. there are other errors but let’s start with this one.

another thing that might be helpful - i’m working on porting earthsea to ansible, and this commit shows you everything you need to do in order to add a new app. it’s for grid but might still be useful (and it includes a support for presets). once something like that is set up you basically just need to write code to process key presses and update LEDs.

Thanks!! I’ll be looking into your earthsea/ansible port. On a side I was getting main.h compile errors when hello_state was uncommented and it was due to something regarding the i2c address, but I’ll look at your port and see how you handle this-- I really appreciate your help with this!

So this project has kinda fallen to the wayside for me since starting a new job, I just haven’t had the free time to keep working on it
@tehn sorry to ping you but it seems like there’s a decent amount of interest in this (and it seems like it would be a very good addition to Ansible), is there a chance that this can be a feature request for future Ansible firmware?

have you done any more work on porting this over to ansible? i know youre probaby busy. thought id check :smile:

Ansible + Arc (Levels) features requests
#23

i have no idea how to do it, but maybe this is something that could be handled by crow? it has 4 outs…

#24

This is something I still think about but just haven’t had the time and honestly the learning curve is a bit too steep for me to do in a short period of time-- but I still stand by that this would be a really good feature addition to the Ansible + Arc combo

just throwing this idea out there too, would it be possible to have arc/ansible be a sort of reel to reel tape player when paired up with ER-301? With four dials the arc can represent two seperate tape machines, the lights would indicate the speed/location of the tape… anyway, just an idea
