Thanks a million, works as a charm on my Core2!

@m5stack This font maker for Aurdino is it correct? Not for uiflow and there is no way for Uiflow? At least only for numbers... You can add some big font only for numbers.

Hello @xxxa0c

you are welcome. Glad to hear you got it working again. And thank you for reporting back.

Cheers
Felix

I met just the same issues at the begining of use my Core2, but later I figured out that its just a problem of M5Burner and M5Stack project immaturity. Only UIFlow and Core2 factory test apps are compiled properly for Core2, other programs listed in M5Burner compiled for M5Stack Core and incompatible with Core2 (you can recompile they using sources and proper includes). Anyway after "bricking" the Core2 you can easly burn UIFlow or FactoryTest or another manualy compiled program through M5Burner or PlatformIO or standart ESP-IDF toolset from Espressif. Its not a real brick state, but just firmware incompatibility.

Has anyone been able to drive two DC motors from the go plus 2 and core2 stack ? I am facing a problem at motor A which only rotates on values greater than 0 to max 127 , but goes not change direction on negative values . Though motor B works absolutely fine . I tested many motors each showed same behaviour at mot A port and worked fine at mot B port .
Is my goplus2 damaged ?

I mistaking posted this in core2, but wanted to chime back in as I have it working. Still not sure how to get the right port with my gray but if someone finds this I wanted to link the solution.

@delchi I take it you are using UIFLOW online.
In that case it just means that the server dropped and crashed due to the amount of people online.

You have to convert the image to indexed websafe before saving and converting to a c array. This can be done in both GIMP and illustrator.

Hi @mikemoy ,
Sorry to reply you so late.We have compiled some APIs, which can be seen here.

I agree. Example projects and code specific to the Core2 are mostly missing which is sad because it seems like it could be a great hardware platform for learning. Right now, ours is just sitting on a shelf awaiting useful instructions.

@erich said in Fail to burn:

@ajb2k3 Honnestly I litteraly spent days trying to solve it... esp forums / github, MStack support, etc....
I don't think the problem is coming from the chip, from the hours I spent reading forums and github threads it looks more like a bad implementation of python / esptool / pyserial in big sur.

And yes you're right: i want to be fair here, I downgraded mainly because of this issue with my core2 but also because I had continous crashes with Safari and the system was sometimes slowing down without any reason.
First time I have to downgrade an operating system...Big Sur is definitely a Big Sxxt :)

I'm so distrustful of updates that I'm still on mojave!

use ESP.restart();

@wa-berlin said in Core2 how to know the current battery level:

batPercentage = ( batVoltage < 3.2 ) ? 0 : ( batVoltage - 3.2 ) * 100;

micropython welcome :

batPercentage=0 if batVoltage<0 else round((batVoltage-3.2)*100) lcd.print(str(batPercentage)+"%",0,0)

;-)

hello,
i use the nice lvgl Lib to do That.

create personalized button add event on the button

example :

from m5stack import * from m5stack_ui import * from uiflow import * import lvgl as lv screen = M5Screen() screen.clean_screen() screen.set_screen_bg_color(0x00000) lv.init() # create screen scr = lv.obj() # set Background screen scr.set_style_local_bg_color(scr.PART.MAIN, lv.STATE.DEFAULT, lv.color_hex(0x000000)) # create button btn = lv.btn(scr) btn.set_size(80, 80) # change style btn.set_style_local_bg_color(scr.PART.MAIN,lv.STATE.DEFAULT, lv.color_hex(0x0000ff)) styleButton = lv.style_t() # create style styleButton.set_bg_color(lv.STATE.DEFAULT, lv.color_hex(0x0000ff)) styleButton.set_radius(lv.STATE.DEFAULT, 0); styleButton.set_border_color(lv.STATE.DEFAULT, lv.color_hex(0x0000ff)) btn.add_style(btn.PART.MAIN,styleButton) #define this style # callback action def action(btn, event): global src if(event == lv.EVENT.CLICKED): btn.set_style_local_bg_color(btn.PART.MAIN, lv.STATE.DEFAULT, lv.color_hex(0xffffff)) btn.set_style_local_border_color(btn.PART.MAIN, lv.STATE.DEFAULT, lv.color_hex(0xffffff)) # define callback btn.set_event_cb(action) # load the screen lv.scr_load(scr)
