a description of what points_3d is ?
my assumption
[X,Y,Z , R, G, B]
XYZ as triangulated locations based on the triangulated scan of the sensor.
RGB, values set in a range based on smallest and largest Z value
Your assumption is correct!
We've updated the documentation to make this clear. Check it out here: https://taulidarcommon.readthedocs.io/en/latest/api.html#module-TauLidarCommon.frame
@Nate said in Can't install TauLidarServer:
You're trying to run that command inside the python interpreter in interactive mode, but you need to run it on the command line in your shell. The python command will also need to be in your path, there was a checkbox for that during install. (You may have already selected it and be good to go.)

How did you install python 3.9? Whenever I install python3 it gives me 3.6
Check out the Python Beginner's Guide for more details on installation and an intro into Python itself!
@SimonPR For order-related issues, your best bet will be to talk to/continue reaching out to customer support where you placed your order - we have no control over individual orders placed with our distributors (or their ship dates).
On our end, we're doing our best to keep our distributors supplied during this chip crisis and keep everyone informed about what's going on.
Omega2S+ (OM-O2SP) and Omega2S (OM-O2S) resupply to Mouser has shipped
Omega2S (OM-O2S) and Omega2 (OM-O2) resupply shipment to Digikey has gone out
Check back with Mouser + Digikey in the coming days for available inventory, we anticipate units will go quickly once they’re back in stock.
Next resupply shipments will be going out in July
@haythem looks like it should work. try it out and let us know how it goes
The hardware SPI can only drive 2 devices, as there is only CS0 (already used by internal flash) and CS1.
If you need more than 1 additional SPI device, you'll need to resort to software (GPIO based) SPI. (Also known as bit-bang SPI).
Install the required kernel modules
opkg update
opkg install kmod-spi-gpio-custom
Then load the spi-gpio-custom kernel module:
# configure software GPIO SPI
# bus<Y>=<devid>,<SCK>,<MOSI>,<MISO>,<mode>,<speedInHz>,<CS>
insmod spi-gpio-custom bus0=1,11,5,4,0,100000,18
Where
spi-gpio-custom. If you need multiple software SPI, you need to specify all of them on the same insmod command line, and specify parameters like bus0=... bus1=... bus2=...The example above will get you a /dev/spidev1.0 on pins 11,5,4 and 18, in mode 0 and with 100kHz speed.

@haythem Sounds to me like the same issue from this thread: https://community.onion.io/topic/3830/really-bad-lag/5
See my response there
And please refrain from making duplicate threads about the same issue
@crispyoz yikes, they had 440 when I posted 2 days ago...
I'll post here again when we send out more resupply shipments
Initial Omega2S+ (OM-O2SP) resupply shipments to Digikey and Mouser have gone out!
It looks like Digikey already has Omega2S+ listed as in stock.
More resupply shipments will be going out mid-June.
@haythem quickest and most straightforward way would be to use the os.system module to execute the commands listed in the hardware pwm documentation article
@eblasband closing the loop here:
Omega2S Hardware Design Guide v1.1 was just published with an updated section on the WiFi antenna
Let us know if that's more clear and if there's anything else missing from the documentation that would be helpful
@crispyoz I suggest checking back on Mouser + Digikey's quoted delivery time in the coming weeks. They might be using a worst case estimate at the moment - so it might improve with time!
Where can I go to scream !?!?!
Lol! I personally found nature walks really helpful when we kept getting hit with news of 2x, 3x, 5x component price increases. Only have a few new streaks of grey hair 
@crispyoz Looks interesting, but can you give some context?
@crispyoz oversight on my end, apologies!
The Onion Store has been updated with the new direct from pricing at MoQ. And you can request the updated price sheet here.
We're assuming Mouser and Digikey will adjust their prices somewhere in line with our MoQ pricing.
EDIT: Looks like Mouser has posted their new pricing as well!
You'll have to check directly with Mouser/Digikey on how they will handle price changes for back-orders.
@crispyoz That's right, prices for all Omega2 modules have increased as a result of these new market conditions.
We've put up a blog post on the impact of the chip crisis that goes into more detail.
Along with that, there's a new chip crisis status page that we'll be updating with any new developments. Our goal is to keep everybody informed with what's going on.
@SimonPR and others in need of inventory asap:
We’re resupplying Mouser and Digikey as fast as we can - resupply shipments are going out in early to mid June.
Going through Mouser or Digikey will be the absolute fastest way to get units.
@Nagarjuna-Reddy Pin multiplexing is controlled by the GPIO1_MODE register (the omega2-ctrl utility is an easy-to-use interface for changing the pin multiplexing settings but it doesn't include the SD pins)
My suggestion is to use the devmem command to change the SD pin multiplexing setting to gpio in the GPIO1_MODE register, and then test changing the gpios.
See the MT7688 datasheet for more info on the registers, and run devmem --help on the command line to see how to read the registers.
Good luck!
@francisco-vieira I agree with @crispyoz, this sounds like a handshaking issue - my guess is in hardware.
To check on this, you can use the devmem command to read the UART0 status registers. I would start with the Line Status and Modem Status registers.
See the MT7688 datasheet for more info on the registers, and run devmem --help on the command line to see how to read the registers.
The 64 kB DRAM in the serial output is the key here. It indicates a hardware issue: the RAM is no longer connected to the MT76 SoC.
The 64kB in the screenshot is a small cache of DRAM that's internal to the SoC.
This issue can be caused by a few things:

Posting an update on this topic received on our helpdesk:
After a lot of investigation, we already identify and solve the problem. The problem was on a cable inside our Gateway that induces electromagnetic signals on the Onion Omega 2+ when the GPRS is in use. We already protect the Onion Omega 2+ from electromagnetic signals and right now we are confident that it is solved.
