just found another side for what I can do without beta dev kit, I think I will focused on Axiom Remote for now.
05:47
tjstyle
but instead using PIC32, I will use STM32 in development.

tjstyle
remembering I was have similar project with Axiom Remote, it's RGB LED controller for placed in car dashboard.
06:27
tjstyle
it's full touchscreen operation, using STM32F4.
06:29
tjstyle
just need to add some hardware input (button, encoder, etc.) but need to learn for menu and another stuff that needed in Axiom Remote.

morning folks!
08:39
Bertl
hey tjstyle! regarding remote: why not ... but note that we also finished the first prototype hardware for the AXIOM remote recently
08:40
Bertl
http://files.apertus.org/HARDWARE/AXIOM/BETA/REMOTE/
08:41
Bertl
while it features a touch sensitive display, the folks responsible for the ergonomics decided to focus on 'real buttons' for the haptic feeling and feedback instead of touch
08:41

08:44
tjstyle
yes, I was read in wiki then I will take a look for the prototype as base for my design.
08:45
tjstyle
because for now only that segment that I can focus without dev kit.
08:46
tjstyle
and yes, I will also add real button also haptic feedback for touch and encoder using motor buzzer.
08:46
Bertl
well, there are probably some areas where you could work on ...
08:47
Bertl
like for example we were asked several times about a simple audio shield
08:47
Bertl
i.e. something you can use to input/output audio, maybe even with proper mic supply or so
08:48
Bertl
that might be your area of expertise while at the same time reasonably independant from the axiom camera
08:48
tjstyle
one thing that I need to know now, what interface used between camera and remote?
08:49
tjstyle
hmm, audio shield was also interesting area.
08:49
Bertl
that is something we haven't decided yet, the most likely interface for the start will be USB
08:49
Bertl
i.e. the remote gets the power via USB and data is exchanged between remote and camera
08:49
Bertl
(this doesn't require any additional I/O interfaces on the camera)
08:50
tjstyle
ok, that's possible also in STM32.
08:50
Bertl
the better option for the future is probably a bidirectional serial interface as it is more robust than USB
08:50
tjstyle
I also think about using USB or UART
08:50
Bertl
and there isn't much data to be sent between remote and camera
08:51
tjstyle
uart will more easy with defined protocol than usb I think
08:52
Bertl
both can be easily tested on a PC, either directly via USB or via an RS-232C USB adapter
08:52
Bertl
the prototype we did (for the remote) features USB, UART and I2C as potential interfaces
08:52
Bertl
(the one I linked above)
08:55
tjstyle
So I will make my own design based on prototype design above, no problem if my design will not submited as officiall Axiom remote. only as alternative remote.
08:55
tjstyle
then also playing around with audio shield
08:57
Bertl
yeah sure, we do not have a problem with alternative solutions
09:09
anuejn2
yeah audio shield would be awesome :)

maybe something like 2x xlr in and 1x headphone out

tjstyle: I would put the faders next to the edge, that way you can operate them without having to take the eyes off what you are doing
09:40
tjstyle
anuejn2: noted!
09:42
tjstyle
comradekingu: analog in is ok. and for digital in, actually how much buttons that actually used?
09:43
tjstyle
STM32 have 16 EXTI pin input, 2 encoder will take 4 EXTI. so 12 left for buttons
09:44
tjstyle
above 12, so I will not use EXTI feature, just scanning buttons each cycle.
09:45
comradekingu
anuejn headphone out needs an amplifier
09:46
Bertl
off for now ... bbl
