Thanks I did just miss the "INPUT_PULLUP" set up All working now

Hello @Paolo sorry no, I do not have any new information about that. Maybe try to contact M5Stack support? Thanks Felix

@ajb2k3 said in TF-Card: @imahgin The TF adapter will be added to the BASE menu in UIFlow when the programmer get through the back log and there is no TF UNIT. Ok, thks. In the meantime, I'll use this code to access to the microSD BR

@ajb2k3 said in Maximum output power: @imahgin Yes, the only difference is that the lite lacks the screen. Thks Adam

@Kees The above finally worked with the M5StackSimpleServo library. However it turned out that I could only control speed and direction. Using degrees 0-90 for retraction and 90 - 180 for extending. It is not possible to position, this was finally confirmed by the seller. Again searching for actuators that can position.

I'm not able to get https://docs.m5stack.com/en/atom/Atomic CAN Base to work with the AtomS3, immediately TWAI_ALERT_ERR_PASS, TWAI_ALERT_BUS_ERROR https://docs.m5stack.com/en/unit/can works, though. What CAN library did you use? With what pin definitions? Thanks in advance!

@felmue it also sounds like you trying to use it inside a building which block the GPS signals. You need to hang the GPS antenna out of a window to get a GPS signal

@Uzr66 It might be helpful if you share the code with us and elaborate a bit further.

It turns out that part of the solution is sending the host mode to the ATOM. My code above did not do that (thus none of the commands were working.) Not knowing the full state machine of the ATOM QR, I somehow assumed host and continuous were opposite modes - but I was mistaken. I'm still unclear on how to send the Setup Code Prompt that is shown in the QR code. So I have a version that makes no sounds - but I'm unclear if it was totally from the Serial2.write calls, and not from the scanning of that Setup Code Prompt mentioned here thanks,

It may be cutting it to protect the LDO in the Atom. I once tried this and killed the LDO in a pico so I do not recommend it.

@gerber said in I2C with Atom S3 and PoE Base W5500: ATOMIC PoE Base W5500 ATOMIC PoE Base W5500 occupies PIN ports and uses SPI protocol from what I can see, [image: 1710777816277-atom-poe-resized.jpg] so groove port on atom light is still available (TypeC x 1, GROVE(I2C+I/0+UART) x 1) [image: 1710777834249-atom-light-resized.jpg]

To run devices like this from an external supply I'd recommend a little Buck regulator board such as the one Youmile does (https://www.amazon.co.uk/dp/B07TTH6C3J). You can then set the output to fixed 5V and drive the input from anything - USB 5V from a breadboard, a 9V PP3, 12V or 24V car, truck or boat battery etc. - with no worries about blowing anything in the Atom.

Hello @Felix22 no, sorry, I don't have such a list. But if the error code is from an AT command you should be able to find its meaning from the AT command document linked on the product page. Thanks Felix

@lukes There is no schematic, which is unusual. I "made an Issue" with M5Stack's GitHub page for AtomS3 last year about this, but, nada.

I uploaded an example to UIFlow2 project zone on how to use the AtomS3lite and ENIV in UIFLOW with MQTT last night
