M5StackSAM - Application Menu Library

[面包]

不知楼主是否看得懂中文~哈哈
这个例子非常好，已经借用，谢谢作者TomSuch~
另外，建议做菜单列表，比现在的菜单页面直观一些。
APPLICATION
1.APP1

SYSTEM
1.SYSTEM INFO

@reaper7 shows strange values: VCell: -0.0213V SoC: -1.00%
what's going wrong?

@jwdberlin
Hi, just checking... have you added a MAX17043 "battery gauge module" to your M5Stack in some way - perhaps soldered to the add-on Battery module as per reaper7's example ?

[reaper7]

@jwdberlin - i2c scanner app show max17043 at address 0x36?, your master ino has Wire.begin(); ?
Try first with regular library:

@JimiT - good question :)

@reaper7

Hi Reaper7, I'm planning to do this mod.

Could you please share some details on how you've wired the MAX17043 ? I am sure others would also be interested.

So you've removed the battery connector from the MAX. Looks like you are using 7 of the 8 pins on the the MAX... NOT using the Quick start QSTRT pin from what I can see. Then i presume SDA to G21 on M5Stack; SCL to G22 on M5Stack....

Is that right? And the rest ? Thanks !

[reaper7]

cutting pcb is not necessary,

cutting wire between ACCU+ and VCC also not necessary
but I do not want drain accu by max17043 when m5stack is off

REMEMBER! If wire between ACCU+ and VCC are not cut (on the max17043 pcb) as it is originally,
then connect only ACCU+ pin to M-BUS BATTERY and DO NOT connect VCC to M-BUS 3.3V

@reaper7
Excellent thanks very much !

[jwdberlin]

@jimit Thanks - after rereading I noticed that a separate module is needed :-) Just ordered some of those...

A bit off-topic:
Can someone using a battery gauge indicate how long does the 150mah battery takes to charge on an M5Stack limited edition ? (assuming ESP is sleeping)

(FYI, with the screen backlight turned off, and not connected to any network, the battery lasted for 40 minutes with the ESP not sleeping)
