Hello, Did you end up finding a solution ? This is my issue and I think it may be related :

Hello, I am trying to integrate a RTC module (DS3231). It works fine as long as I don't use the M5Stack library. As soon as I combine M5.begin() with Wire.begin() there seems to be a conflict. Scanning I2C reveals 2 devices :

0x57 - M5 LCD ?
0x68 - RTC Module DS3231

Any clue as to what is going wrong ? What PINS are used by the LCD ? I suppose 21 (SDA) and 18 (SCL) ?

Kind Regards,

Tony

@al-mo you can specify the user name and password in the code. I cant remember how its down as I dont use Arduino (i just remember seing a demo) @lukasmaximus may know when he make it back on line.

@thrasher
latest Firmware fixes this.

I didn't say it was clean, it's a workaround. You can buy grove to dupont converters.

You can only write 1 file at a time. Please bear with me as I’m currently testing and logging the A’s functionality

There is a fix in the GitHub repo for Arduino https://github.com/m5stack/M5StickC/pull/52 .

@skink said in Application M5 AC Socket:

Hi at all,
is there a test program or an EasyLoader program with which I test the M5 AC socket !?

I have M5 stack with RS485 to TTL Unit or also a M5 Stick-C with M5StickC RS485 HAT.

Thx! Skink

The only known information is found here: https://docs.m5stack.com/#/en/app/ac_socket . I’m still waiting on one to be delivered

@lukasmaximus Thanks so much for your reply! Sorry I missed it. I found the Arduino sample and confirmed it works. Somehow I had been led to believe from issues on Github that it was only supported on Fire, but the battery sample works on my M5 Basic (black).

It is probably better not to connect PIN 1 of the NS4148 but pin 3 the buck converter EA3036 to pin 5 since otherwise you have a bigger power consumption. You could also remove R23 in that case.

@ajb2k3 Thank you very much!!! :D :D

@ajb2k3 That's great news, thanks a 1,000,000

@ajb2k3 said in Application M5Stack Demo-Board (Factory-Test):

Try deleting the circle at the beginning of the line.

I've already done that, erased the circle in front of the bracket.
But nevertheless it runs only up to function 6!

Just found out, that I get the following error message working with Arduino 1.8.9 when I load the code into Arduino !!
Error message : "MFRC522_i2C.cpp" contains unknown characters. If the code was created with an older version of Arduino, you might want to use Tool -> Correct Coding & Reload etc. etc. to correct the code.

But even afterwards the program runs only up to function 6!

Click on More Info and there is info about connections.

Hi M5stack.

Would it be possible to add STEP 3D models to all products. It's very convenient for project planning.

Thanx a 1,000,000 for taking the time to help me.

Oops, my bad! I had also been playing with a Heltec 32 WiFi kit, and forgot to change the board (how embarrassing).

I am still indoors, so will either need to use a battery or, perhaps, sit by the window to test GPS.

At the moment, after a few seconds the software reports "Brownout detector was triggered" over serial, then reboots. I will investigate that & ask a new question if I can't solve it. Sorry to have taken your time.

this post say that you can!!
