What are the switch settings for Core? Why can't M5Stack just put the switch settings for each in the document? Instead they have this baffling interactive chart that does not seem related to anything at all.

Hi everyone,

In case somebody would be interested, here is the modified version of the example code StepmotorPulse_M039 working with M5Unified.h and Espressif API updates.

Tested with an old M5Basic.
In retrospect, it's relatively obvious.

Hi guys

I noticed that my M5PaperS3 touch screen is slightly less sensitive when running from battery. Touching the screen with more than one finger helps.

Notes:

Touch wake-up is only possible in ESP light sleep. Please find and example here. Touch wake-up from ESP deep sleep is NOT possible as that would require the touch interrupt line to be connected to a so called RTC GPIO which is not the case in M5PaperS3. Touch wake-up from shutdown mode is NOT possible as the eInk display and touch IC are not running in shutdown mode.

Thanks
Felix

@felmue Thanks so much, that fixed it...

@JourneymanWizard Please Email M5Stack support directly and PM them using twitter.

@erkel
It is working now.
Just a noob issue.
It was the endianesse of the values. it gives the output as expected when converted to little endian, rather naturally reading the value.,

@felmue Thank-you - I had completely misunderstood :-)

@ajb2k3 The relay was not connected. I connected the Core2 directly to a Hub and used the following code. Do you see something that could be the reason for the error?

@mippen
which actually module are you using?

@felmue

Okay, I will try to do that once I've got the required HW and SW to do so.
Thanks for the tip.

@lnsy-strs
yes you can

Hi Win,

My is not working too.

Pinout is the same as stated on https://docs.m5stack.com/en/unit/unit_cam

@ajb2k3 thanks.

I did not there was a different port version of the sensor?

@ioamas
According to the schematic diagram, the 5V of the Pogo pin is directly connected to the VIN pin. So I think maybe you can determine whether the Pogo pin is connected by judging whether the battery is connected

Hello @ioamas

thank you for reporting back. I am glad to hear you got it working.

And sorry you had to sort out a not so well assembled Battery Bottom2.

Thanks
Felix

@teastain thanks for your response, I understand that.

Hello @Marc-SKIL

unit EXT.IO2 can only control one (1) RGB LED per output. So what you get is correct. Have a look at the protocol here.

Thanks
Felix
