@felmue Finally got it working correctly. In addition to your code, I initialised the Pahub, and then changed the dip switch to 0x71. Additional units work fine when assigned to 0x71.
Thanks for the help!

@Slartibartfast why use xcode?

@felmue I followed the instructions, and am getting this result"

Traceback (most recent call last):
File "<stdin>", line 21, in <module>

Here is the relevant code

Having difficulty with getting my ENV III Unit recognised. Setup below:

UIFlow2.0 AtomS3R v2.2.8
PaHub v2.1 - DIP switches on factory setting.
ENVIII Unit

The ENV III works fine without the hub. but will not work in any assigned port, whether on it's own, or with other units.
Other I2C units work as expected. Only the ENV III has this problem.
All channels tried.

Has anyone else had this happen?
Thanks in advance for any help.

@ajb2k3 There was no previous firmware that I installed. This was an out-of-the-box installation. I downloaded the latest update - I think 2.2.7 - and that's when the problem occurred.
Also, when I went to press burn, there was no opportunity to erase before burning.

Moved from General

Experienced a strange event while using my ATOM S3 Lite for the first time.

MacOS

M5Burner was already running when I attached the device.
Downloaded the latest uiflow2 dated 29-05-2025
Configured, and started burn, which ran quickly, without the usual bind request.
Started a new project.
Connected, but was unable to Run or Load.
Process running in terminal installed itself as something suggesting a BT Beacon, and established
a WiFi AP on a 192.168.4.1 IP. It also appeared to be transferring data.

Unfortunately I don't have a copy of the output.

I restarted M5 Burner, and a new update from the same date was available. Burning this version solved the problem.

Does anyone know what happened here?

@ajb2k3 The point of EZData is that it stores data in a cloud, making it accessible from anywhere in the world. Also, you can set up an mqtt server on a €30 Pi Nano, a NAS, or pretty much any other computer with a network connection.

@ajb2k3 Thanks for the suggestion, but I already looked at that, and decided not to get it, as it's EOL and comes as a kit with a module I don't need.
The plate used in the video is perfect.

@I_am_Exiled When I get situations lie that I just use M5 Burner to erase and start over

The Scales Unit video shows it mounted with a perspex weighing plate. The plate would make a great accessory, or include it in a kit.
