Thanks for the tip @flypeek

I checked with my Hello World code and this worked.

I did not expect the AtomS3 to be that different to the original AtomMatrix. However I just confirmed if I change the "board" to just M5Stack-Atom all the original code compiles.

I would have expected big changes if we referred to the ESP32-C3 with the new RISC architecture, but the S3 was fairly similar I thought.

I presume it has a new board definition due to the LCD screen on the AtomS3. If I can get the Zigbee unit working nicely, I might port the example over and post up a PR in the AtomS3 library.

Many thanks again @flypeek you have unblocked me and I can keep moving forward (I hope).

Hi @Exie, have you managed to talk to the Zigbee unit through UART or managed to comprehend the example code given by M5Stack?

Regards,
Ameer

Finally got the notification today and put an order in.

I was tempted to order a heap of them, but given they are obviously in short supply I ordered a minimal qty so I hope others can get some too. They look fantastic!

@exie @felmue I have never worked with micropython, however ESP32 can act as a slave on the I2C bus without any issues, irrespective of the pins that are used (any pair of GPIO can, in fact, be used as front-end for the I2C interface). I've taken a peek to the linked thread and the idea of continuously polling the bus to reply to an address as a slave is quite cumbersome and to say the least, inefficient.

They are available only as PH2.0 4P connectors you can order them from china or on eBay but they are white SMD mount devices as you can see in this image.

The coloured ones I are spare from M5Stack projects and haven't been able to find a source of them yet.

If you still can't find them message me I can sell white THT ones for GBP £4 for a pack of 10 but there will be P&P to be paid on top of that price.

I was not able to have my Atom Matrix interact with the OV2640 Unit Cam... 0_1695488192875_d87c87d2-d834-4fbc-b634-88cddafb3b29-image.png

@Exie were you able to connect your Atom Matrix with the Unit Cam and have the Matrix retrieve the Unit Cam output?

By way of extension, the bluetooth statck doesnt seem to be in the UI Flow 1.7.6 image for the Atom Matrix:
