Yes, but that only works if you drag a line to the screen and manually pre-define the placement and dimensions. You can then alter those later, but it's just the one line.
I want to programmatically draw multiple lines (via LCD.line) with random color(s) and there does not seem to be a Blockly way to achieve that (I'd prefer not to delve into executing Python code for this...)
I was thinking of a project to teach my nephew programming, and wanted to pick a random color from a list by name, but none of the the blocks in Graphic or Screen treat color as a variable.
I did find this old feature suggestion in the forum, which is how I would expect it to work, given a presumed "set variable to RGB values" block...
RE: UiFlow interface suggestions
Is there some other way I am missing?
@ozbk I wonder is there a feed URL I could poll for new firmware releases? Like a index.rss or some such (presumably a simple JSON endpoint these days...)
@ozbk Thanks for the link. Would have been so much easier had I found that myself!
I was able to get UI Flow Desktop IDE to download eventually - after I hooked up o.g. Stick model with diff USB port address (but maybe it was a coincidence and the servers were just unusable for the twelve solid hours until just after I posted...)
I still could not burn anything with M5Burner or Desktop IDE burner but the Burner_Mic worked OK after I pulled it out of the package contents... it was still quite tedious. Mostly because of bugs in the _Mic app with how you need to drop the json file, then pick all of the right menu options a bit blindly...
I should probably write a script now to just "do the needful" without any of the GUI burners... BUT I would never have persisted to that point without the _Mic app guidance to learn the arcane esptool syntax, so it was a huge aide.
I found the original creator on twitter and he let me know that the lock in the video is a Sesame from Candy House. [EN readers scroll to bottom and toggle menu in right corner]
The depicted usage from M5StickC is over WiFi via HTTP API (so it does go through a cloud gateway) - total cost is just barely over $200 USD with that additional cost.
Huge advantage to the Sesame lock is that it goes over your current deadbolts, no need to remove existing door hardware at all. (I basically replaced the handle set and deadbolt when installing the smart lock I have now...)
Kickstarter was last summer : https://www.kickstarter.com/projects/candyhouse/sesame-your-key-reinvented
I guess power is reason they dont just put an ESP32 in the dang lock... and security is why you cant just connect bluetooth from any old dev board, just locked down smart phones... My preference is that I do not believe hardware providers will securely and permanently provide service of remote unlock. Do you mail a copy of your house key to your Alarm company? No...
Is there a URL I can download the 1.4.2 firmware from?
(Currently working with Stick C but I have Cam F and Faces models as well...)
I can use the offline version of the UIFlow Desktop IDE to develop 'blockly' apps, but it repeatedly nags me about upgrading to Firmware V1.4.2... which the IDE can not do successfully.
Neither the UIFlow-Desktop-IDE nor the official M5Burner are able to 'burn' firmware on Mac (AFAIK) I was able to use the unofficial M5Burner app by Micono (aka Burner_Mic) to put the V1.3.2
Once flashed with Burner_Mic, I seem to have full use of the UIFlow Desktop IDE app (but maybe some of the UI glitches are a symptom of same problem)
The particular problem with M5Burner seems to be inability to download any firmware. The UI does warn it has to be downloaded, but clicking the icon which seems most likely to do that triggers a brief "working" indicator overlay but fails to do anything (or error conspicuously)
Exploring the app package contents for the official burner reveals the 'firmwares' folder is empty (and the main feature of Burner_Mic seems to be coming WITH many firmware sets as part of the app download, but storing them external to app package...) which jibes with the futile download experience.
The 'firmware burner' built into UIFlow IDE seems to be the same code, and although the path is slightly different, exploring the app package contents likewise reveals an empty 'firmwares' folder for that as well.
My two cents: You should just store them in "$HOME/.m5stack/firmwares/" or some such normal but hidden folder location if you cant make the app-package-internal storage location work...
Until this is fixed up, I need a download URL so I can try to get Burner_Mic to work with v1.4.2 please.
There is a old thread with very DIY example of unlocking a door on the forum here: M5StickC Door Locker
but I am more interested (as in would readily buy...) the lock as shown in this Smart Door Lock video from the official M5Stack Blog
Does anyone know how exactly this demo was done? What brand lock is it?
Was the protocol Bluetooth? Wifi? HTTP Post through 'cloud' back to the lock?
Some other mechanism?
Context: I have a popular brand smart lock that I don't love, and have not found anything better. I want it to be more open (especially to M5Stack) but ideally without requiring their cloud/gateway. Less than $200 USD would be very welcome.
PLUS I have a pile of M5 stuff I am itching to do more with ...
Thanks for any assistance!
