Blade detect/Blade ID

Proffieboards
1

Hi All

sorry for pestering on this again but i’m still struggling to picture how this all works(i struggle to absorb words but diagrams and actually doing always helps me), i might have to much info about it in my brain now also so hoping i can get it sorted :slight_smile:

this is currently how i am wired up(V3 board) except i think my neopixel connector is v2 style as only using data2 and both resistors are still there for parallel leds, data2 is wierd to data1 on the proffie though

now this is where i get confused and info overload for me, i was wanting to implement the blade charger with blade id enabled and this is where my brain goes to mush

“so I can use Blade ID to turn off every blade but the main blade. Note that when I install my Proffies I always add a 22k resistor between Data1 and 3.3v so I can use the “true” resistor values for Blade ID”

a reply from the man himself profezzorn
“Yes. It also requires a small configuration change to use the right blade ID class:”

so this is how i think it’s done excuse my jedi level paint skills lol

it feels wrong to me to just wire something to +voltage but have the bits needed to do so, but i then came across this for V3 listings to purchase a board

  • Two CPU pins are already tied together for Data1, making blade ID work without additional components

is nothing else needed now for v3’s or do i still need the wire from 3.3v to data1?

thanks for looking and sorry if this post is hard to read

This is a good question.
Your quote above should likely be incorporated to the POD page to update usage with Proffieboard V3.
However, which Blade class ID isn’t clear (snapshot, internal, external) so hearing a reply from @profezzorn will be helpful.

Please read this post by Proff:

You don’t have to do anything: ProffieOS already knows which BLADE_ID_CLASS to use, which pins to use and how to do Blade ID. Just use Data1 and that’s it.

so all i need to do is hook up the blade detect pin and then add this to my config?

#define BLADE_DETECT_PIN blade5Pin
#define BLADE_ID_CLASS SnapshotBladeID<bladeIdentifyPin>
#define ENABLE_POWER_FOR_ID PowerPINS<bladePowerPin2, bladePowerPin3>

and use different ohm resistors on each blade?

obivously i would need a blade config also for each

Yep. That’s how it’s supposed to work.

hopfully this can be corrected in the config or it doesn’t matter and also highlight the error , the config generator has got free 1 labelled as free 3 so i had free 3 in my mind and soldered the blade detect wire to free 3 not free 1

if can be fixed in the config would i change #define BLADE_DETECT_PIN blade5Pin to blade7pin?

as blade detect didn’t seem to work, will also try a serial connection for the first time tomorrow to see if it sheds light

thank you all for the help as well is very much appreciated

Yep, as simple as doing that change. You can test Blade ID with the ID monitoring feature.

had to use blade pin 9 but happy to report blade detect is working, now to mod a blade and test blade id then onto building the charging plug :slight_smile:

thank you all again

When you build the charging plug, use the same + and - that charge the Proffie to power the Pixels. If you use the OUT + and OUT - (like is described in the graphic) the resistance will be all over the place.

This is not needed (nor helpful) for a V3 board.
V3 already has what it needs internally.

hi all

thought i had everything set up but could be the charge plug, i was assuming even without power it would be detected and swap to the blade input

but when i put my tester on the blade(47k resister) red on data and black on negative i get 47.25k but it does fluctuate some and when i put black on data and red of negative i get 41.18k and fluctuates a little

i need to play with serial connection but a brief look showed bladeid 139.5 when chassis was switched on with blade attached and used the default blade of 0ohms

config is
#define BLADE_DETECT_PIN 9
#define BLADE_ID_SCAN_MILLIS 100
#define BLADE_ID_TIMES 10
#define BLADE_ID_CLASS SnapshotBladeID
#define ENABLE_POWER_FOR_ID PowerPINS<bladePowerPin2, bladePowerPin3>

Preset presetchargeblade[] = {
{ “PwrCell”, “tracks/mars.wav”,
&style_charging,
StyleNormalPtr<BLACK, BLACK, 300, 800>(),
//Also black out any extra blades with StyleNormalPtr<BLACK, BLACK, 300, 800>(),
“Blade Chrg\nLevel”},
};

{ 47000, WS281XBladePtr<5, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presetchargeblade) },

I don’t exactly know what you’re asking or reporting. Is blade detect/bladeID not working hence your measuring tests?
In your post above, did you omit the second blade from your blades[] array?
There should be a second one that uses NO_BLADE.

13

hi yes sorry

i sometimes struggle to get whats in my brain out in words, blade detect i think is working when i insert a blade i get the font sound and when i remove i get the bleep but i don’t think blade id is working and why i did the measurements tests,

this is the latest i have tested with i only have one blade with a resistor at the moment but no font switch with this config either

BladeConfig blades[] = {
{ 0, WS281XBladePtr<108, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presets) },

{ 47000, WS281XBladePtr<5, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presetchargeblade) },

{ 41000, WS281XBladePtr<5, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presetchargeblade) },

{ NO_BLADE,
WS281XBladePtr<108, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presets) },
};

14

I can’t remember if this would help your issue, but do you have #define SHARED_POWER_PINS in your config file?

15

it doesn’t seem like any resistor value is being recorded or sent as i can get it to work when there are only the 47000 blade and no blade in the config but that just seems like blade detect working and any blade will do that switch as i changed 47000 to 30000 and it still changed, the serial out put gives me this
ID: 139.10
Blade Detected
blade = 1
WS2811 Blade with 5 leds.
WS2811 Blade with 2 leds.

i would have thought ID: should be 47000 or something?

{ 47000, WS281XBladePtr<5, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(presetchargeblade) },

{ NO_BLADE,
WS281XBladePtr<108, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<2, blade3Pin, Color8::GRB, PowerPINS >(),
CONFIGARRAY(preset1) },
};

16

I would remove #define BLADE_ID_CLASS SnapshotBladeID<bladeIdentifyPin>
It shouldn’t matter, as that is what the default is, but try it?
I’m not able to troubleshoot this more at the moment sorry. @profezzorn would have the best idea of what to check next.

17

jackpot :slight_smile:

thank you very much, no blade goes to the single font preset, charge plug goes to the charge preset and my default blade with no resister allows all fonts

and ID in serial is showing much higher values

good to know my soldering skills are getting better as well with the charge plug resistors, those things are smallllll

18

Wait. So adding SHARED_POWER_PINS fixed the issue?

19

It might have helped as I added it earlier but removing blade id class snapshotbladeID got it working

I will test tomorrow with shared power pins removed and update

Well you have both blades using LED 2 and 3, so you should leave it defined.
