    Well, and I’m using LFS on my device with Mongoose-OS - this is also faster than SPIFFS.

    @tobozo
    LFS ? reminds me of Amiga

    good evening folks

    I have a stupid question regarding the larger battery module, do I use it with the regular battery module (stack back) and is there anything to be cautious about regarding cell balance for the 2 batterys ?
    tobozo
    @tobozo
    @stonemull I'm quite sure the large battery module is a replacement of the small one, so it's probably not designed for cell balancing.
    stonemull
    @stonemull
    the larger battery module does not have GPIO connectors like the rear, so its not a standalone replacement as you need both modules, I was only talking about "balancing" when you first connect them, both batterys have an onboard BMS anyway, just pulled it apart and measured voltage on the internal battery pins on the header and both cells are at 4.08v, so they are just paralleled. All good. just be nice to find this information somewhere.

    Not M5 but very nice as well:

    Hm ... Case? And where to buy? I think I'm stuck witb my ODROID-GO because of it's good setup, quality and price, the M5Stack crew presents one gadget after another, but targets the far east, because most things you need to buy via Aliexpress abd you wait 2-3 weeks until delivery. This I don't like ... Hardkernel on the other hand are deliverung from Southkorea in one week to Germany and are handling the customs professionally via FedEx - and they established european/german distributors. This is how I may use their module (even with the GameBoy case) as base for our pilot project with our customers.

    @tobozo
    can't buy unless close to Japan or Taiwan ?

    @jsdungeon
    I am close to it in a way ;-)
    I might be biased because Galaxian / Galaga is my favorite retro game ;-)

    BME680 Bosch sensor - does anyone has experience with this one?

    Hi all I'm lukas recent newcomer to the m5stack team. Just discovered this chat through reddit. Look forward to chatting here and hearing your feedback about M5stack products

    @tobozo
    @jsdungeon I played with a BM680 sensor, if you don't mind polluting your build environment with closed source binaries from bosh in order to just use the gas sensor it's fine
    otherwise it's just a very expensive BM*280
    welcome @lukasmaximus89 :-)

    Hi @tobozo admire your awesome work with video playback on the m5

    @tobozo
    thx ! most of the work was made upfront by @mhageGH

    @jsdungeon
    @tobozo thanks for your feedback. Which sensor would you recommend for a precise air quality (PM2.5) monitoring?
    tobozo
    @tobozo
    I don't know I've only tested two different types of sensor so far
    a basic one that came with a 37-in-1 sensor kit, needed 8 hours to get 'hot'
    I tried to apply the same code to the BM*680 and only got erratic readings
    don't have much experience out of that anyway
    Ulrich Rosenbaum
    @jsdungeon
    ok thank you, I'll do some research on that

    Anyone here going to 35C3? I'll be there doing some M5Stack workshops
    Ulrich Rosenbaum
    @jsdungeon
    @lukasmaximus89 Where will it take place?
    lukasmaximus89
    @lukasmaximus89
    Hi Ulrich, it will take place in Leipzig, Germany from the 27th to the 30th. I'll also be visiting makerspaces/hackerspaces in Berlin and Leipzig. So if anyones around it would be great to meet up.

    Hi Lukas, thank you for telling me but I've been too far away - and now I'm even around 11h flight time away from Leipzig ;-)
    How was it?
    lukasmaximus89
    @lukasmaximus89
    Hey guys CCC was great, a bit overwhelming for my first time, but I will definitely attend again. The european hacker/open source scene is very impressive, such diversity an passion at the event. I had young an old attending the M5Stack workshop and hope to do more community outreach in Europe this year.
    @tobozo the lowjs looks cool, Have you been able to get it running on M5Stack?
    tobozo
    @tobozo
    @lukasmaximus89 I tried but there are many crashes with psram
    the only way to use psram without crashes is to make sure nothing else is accessing the SPI while it's being read/written

    HI guys, lukas invited me here as I'm working on a UIFlow book

    @Ajb2k3
    Anyone know what the *nix /dev/ entry is for the M5's com port?
    I need it for my book but haven't got a nix machine available to test on.
    @tobozo @lukasmaximus89 @jsdungeon @mamuesp @stonemull @grooves38 hi all

    @jsdungeon
    @Ajb2k3 Welcome to the club :-)
    Manfred Müller-Späth
    @mamuesp
    @Ajb2k3 - AFAIK it's /dev/usb.... - just test it like this: call ls -la /dev/usb* without the device attached - and then again with the device attached. Then you should see the used port.
    tobozo
    @tobozo
    welcome @Ajb2k3
    *nix dev entries can be /dev/ttyUSBx (with x being the logical port number) or /dev/ttyAMAx
    the /dev/ttyAMA0 is used on some raspberry pi hats
