thank you!
Maiden gets started when pi gets booted like this:

we         327  0.0  0.6 833668  6452 ?        Ssl  07:40   0:00 /home/we/maiden/maiden -fd 3 -app ./app/build -data /home/we/dust -doc /home/we/norns/doc

but it seems not to work. ip:5000 on a browers fails…

if I start it by hand without the -fd flag I get it running but end up with a 404 page

Still having some issues getting norns running. Getting the following error

I don’t have ~/status.wifi file - should this have been generated somewhere?

systemctl status norns-init.service

EDIT - rand ./wifi.sh scan and ./wifi.sh on and rebooted and that got me in business

this is the 800$ question right now [along with the /dev/events stuff :slight_smile:

norns/matron/src/hardware/screen.c

at line 71:

/* Use fb0 if no fram buffer is specified */
if (fb_name == NULL) {
fb_name = “/dev/fb0”;

and line 138:

void screen_init(void) {
surfacefb = cairo_linuxfb_surface_create("/dev/fb0");
if(surfacefb == NULL) { return; }
crfb = cairo_create(surfacefb);

#183

thus - change line 138 to fb1 ?

I don’t have my install working yet so can’t try.

#184

Not 100% sure about this but here’s my instructions/notes for getting the SH1106 OLED display working.

Please test if you like and let me know if you run into problems

thats it!!!

wuhuuu!

after you replaced /dev/fb0 with /dev/fb1 you have to rebuild norns:

./waf configure
./waf

Based on your ps listing it would appear you are trying to use the systemd unit setup - if that is setup correctly the things should be accessible from port 80. If you are starting maiden by hand without the -fd flag then things should be accessible on port 5000.

#187

Thanks. I got it running in the meantime :blush:

#188

i would love that but it looks like the piSound uses all the pins So i am going to continue to hopeully find a software solution but as of now unless i hear something else fabulous [as this surely is]
i am going to tap out or Raspi Norns Dev

#189

Heck yeah! Thanks for the additional work to make that work!

great stuff @reijo , really good progress.

#191

I’m not worried about replicating a pair of encoders and buttons. Those aren’t a dealbreaker for me, and the prospect of integrating an external controller for those didn’t dissuade me from ordering a PiSound instead of some other DAC, either.

(I’m also planning to test whether or not MODEP is a viable backup for my MOD Duo…)

That’s burying the lede, I suppose. I ordered a PiSound last night. It’ll probably take a while to ship overseas, so I’m still only lurking. But, I’m at least that committed now, and I’ve got more of a timeline before me.

good luck ,
with time this nut will be cracked :slight_smile:

ive been playing with a variety of kernels configurations today (between beers with friends) , not much to show as yet, but you learn something on each interaction (if only how to type faster :wink: )

Norns running on RasPi with OLED and USB Audio (also got the oled to startup on boot!)

Anyone got the encoder or button GPIOs figured out?

The ones listed at https://github.com/monome/norns-image/blob/master/readme-hardware.md seem wrong as GPIO39 (which I think means pin 39) is GND… ???

I also tried wiring up with those pin assignments and got nothing. :frowning:

EDIT - the compute module (cm3) in Norns has a different pinout, so that explains the GPIO numbers being higher than are available on the RasPi 3

very nice - what’s your OLED ?

now a bit torn - was going to go with pisound but having the display for this seems very nice.

#196

OLED is an SH1106 chip version from ebay - about $5-6 each
“HQ 1.3” 128*64 OLED Graphic Display Module SPI LCD"

Now… the pisound gets you audio I/O - which is a whole different thing. However, I think shreeswifty said something above that the pisound uses all the available gpio pins, so you might investigate that a bit further.

I’m gonna look into another DAC solution later, but don’t hold your breath. :slight_smile:

#197

yeah - the pisound does appear to (not bought anything yet but going to press the trigger soon)

hmm. questions questions! :slight_smile:

#198

warning pisound
I determined last night that the pisound was disabling preemption, which is i believe the cause for me not getting the performance id hoped.
blokas have suggested i can hack the pisound driver to make it work (as a temp fix, till they can get a proper solution) , so thats my plan for today…

if that fails, im going to transfer a hifiberry dac+, that i have currently on a pi2, to the pi3…

think i might also order a rpi3b+, so i’ll have the dac+ on the rpi3b and pisound on a pi3b as … norns on one, orac on the other :slight_smile:
