I'm totally open to feedback/criticism/insults concerning this project
Hi all, how difficult would it be for me as a coding noob to create an app on the M5 which is recognizing a sudden fall and sends out an e-mail if not picked up after 2 minutes? Something like the apple watch 4 is doing now.
@tobozo - Too bad ... would be nice to use it on Mongoose-OS together with some bigger Flash. Who needs GB of data on an ESP32? And it's a pity it is always connected to the Arduino Framework ... :flushed:
No, storage flash. I use the ODROID-GO as my favorite prototyping device (don’t need much pins as I use mainly SPI and I2C with GPIO extenders and an interrupt pin), so it has 16MB flash - that would be enough for some nice scenarios, no SD-Card needed there ...
What scenario on the ESP32 could possibly use gigabytes of SQLite data ?
not a web server since filesystem access is enough
I don’t know - so that’s the question why the SQLite lib is only using an SD-Card. But I think it’s because of the Arduino awareness … addtional filesystems are not very well known there in conjunction with „normal“ flash chips, so the obvious is used ...
maybe for someone porting code logic from another language onto an IoT, for database reimport purpose ?
when I played with the video format for m5stack I was surprised how fast the file seek was, it was much faster than opening a bunch of files with the same weight
Well, and I’m using LFS on my device with Mongoose-OS - this is also faster than SPIFFS.
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 ?
@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.
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.
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.
