Hi,

It's actually significantly simpler to type an e after the umlauted letters, and utilize a twofold s (ss) for ß. That is how Germans treat they need to.

Hello @littlbee

no worries. I am glad to hear you got it working to your liking. And thank you for reporting back.

Thanks
Felix

@felmue thank you for this quick and excellent reply!!! I will do this. Can you just tell me if I need to specify the pins as GPIO33 or 33 in the constructor

Hello @buzali

no, at the time I used the Arduino environment for my tests. RTC wakeup should be covered by this example.

In UIFlow have a look at the Restart on block. You can find it under Hardwares - Power with M5CoreInk selected as device.

Thanks
Felix

@ajb2k3 ok, I see. But thanks for your reply. I post in this forum if I can figure it out

@felmue

The tip has hit the problem. I have implemented a query of the key A in the callback routine after 1 ms. Only if the key is still pressed the routine is executed. Otherwise nothing is done. Now there are no more key presses from the ghost.

Thanks

Felix; thanks for the tip in the Grove pinout; exactly where I was stuck after experimenting.

@felmue
thanks Felix for your help I now have it working... something was going wrong between moving from USB to battery.

I have downloaded that and it does work.

But, your documentation leaves so much to be desired / it would be great if this could be documented somewhere rather than in a git repo.

Some of us do read documentation / and don't necessarily consider git to be documentation.

Hello @DavidoZ

why don't you try the provided example?

Strictly Serial.begin() isn't needed in setup() as M5.begin() already takes care of that. And for the communication with the SIM7600 you'll need to open Serial2. See above example.

Thanks
Felix

Hello @thkfighter

if you're asking whether there are people using M5Stack Basic Core successfully with UIFlow then the answer is yes and no. I am sure there are many successful cases out there but there probably are some unsuccessful cases as well. For M5Stack Basic Core resetting every few seconds many reasons come to mind: weak power supply, UIFlow firmware not properly burned, incorrect UIFlow firmware, WiFi credentials incorrect, weak WiFi signal and yes, faulty hardware.

Without a little more information it is very hard to diagnose the particular issue your M5Stack Basic Core is suffering from. Could you give a little more information? For instance is there anything in M5Burner log? Is there anything on the screen? If yes, does the WiFi symbol turn from red to green?

Thanks
Felix

Hello @alexylem

only so called RTC_GPIOs can wake ESP32 from deep sleep. Unfortunately GPIO_NUM_5 is not one of them.

Please check out page 15 - Pin description of the ESP32 datasheet.

Thanks
Felix

Hello guys

there is a new version, M5Paper V1.1, available in the M5Stack store. It seems to be more or less identical with the original version, maybe except for the e-Ink screen panel?

Does anyone understand below comment from the M5Paper product description?

'M5Paper v1.1 adopts flexible e-Ink screen panel, which is the same model as that of M5Paper v1.0 hard e-Ink screen panel. All features and specs are the same for both models.'

Is the new and old version actually the same or not? And what is the difference between a flexible and a hard e-Ink screen panel?

Thanks
Felix

Hello Wold101,

Thanks for your answer.

I need to continue to use the M5Stack Core as I have made some backplane electronics and need to use the M5Stack stock.

I didn't know about this post and I already used a diode and had a bug with the ESP. Probably this problem of low battery charge.

The idea is great to use a MAX40200 but it requires extra wiring.

I tried with a capacitor. I have some 4700µf in stock at 63V.

I like this solution, no modification and it works well.

I will test it over several days.

I use this code in stickc as esp receiver for debug. And on other atom lite i use only broadcast datablock with convert to str block with my message. And its works.

This guy shows how to use 2 cores with arduino

@m5stack thnx, I solved this problem - indeed I had to load board definitions

Also this YT-video 'M5Paper Seasons Greetings Display' was helpful: https://youtu.be/Tjz4fGRn8fo

Thanks Paul for this tool, it is working great.!!
