  Hello @Senspix

  I just tried with my SIM7600G (non -H; 3 years old) and M5CoreS3 using aforementioned test program and the modem does react to AT commands just fine after about 14 seconds.

  Recently I purchased a separate green board with a SIM7600G-H on it which I use in the same COM.X module. Initially it did not work. Turns out the green board had a layout error - RX and TX needed to be swapped electrically in order to work in the COM.X module.

  In conclusion: I can use either SIM7600G or SIM7600G-H with M5CoreS3 just fine.

  Thanks
  Felix

  Hello @Cognitive5525

  above measurements have been done via battery connector @ 4.2 V.

  If I use the green connector (and with aforementioned hardware modification) then in shutdown mode I measure about: ~ 1.5 mA @ 6 V

  I guess the higher shutdown current (compared to when powered via battery connector) is due to the DC/DC converter converting +VIN into +5VIN and the battery charger IC which both stay powered even in shutdown mode.

  Thanks
  Felix

  @aradke said in CoreMP135 Debian image:

  The permissions from the original source should be fine, and apt will make sure any further permissions are also correct. Going back to fix already damaged permissions would be difficult and it would be very easy to miss something.

  That's why I spent last night going through the source so I could find where these are set. I could not find the config for the directory like /etc.

  Ah it's the host system that set the file permissions.

  When the image was generated it wasn't compiled under root so directorys weren't set as root but to the permissions of the host.
  The image need to be re generated as root.

  Hello
  I am new to this and I have got some questions about the Atom Step Motor base for Atom lite (sku: K047).

  Why the UiFlow sample code is not using the blocks store in BASE/STEPMOTOR in UiFlow IDE ?

  Why is there a block "init step type" in BASE/STEPMOTOR in UiFlow IDE to set microstep while there is dip switch on board? Which method prevail?

  In the sample code, I suppose ADC to reflect actual current in the coils. Am I right ?

  Thx for your answers

  Hello, I am trying to connect a DS18B20 Temperature sensor (via the one wire protocol) to my ATOM Lite using either G26 or G32 with no luck. If I use G25 it works. Is there an issue with using these GPIO's for a one wire application?
