Hi, I have find a way to use both of them in the same APP. CAN connected to Port C(UART1) and I used UART2 for GPS.

Hello @HappyUser you are very welcome. I am glad to hear you got it working to your liking. And thank you for reporting back. Thanks Felix

@crami25 Hi Crami, just a poke to see if you managed to make any headway with your color calibration? best,

Cheers, I'll be interested in your findings! As you might have seen in this small "saga" here, I have a similar problem with some (but not all) of my 30+ CoreINK devices which have a similar power control circuit.

Hello @stoeff99 from what I can tell the firmware versions offered by Espressif do not have Ethernet enabled by default. I also do not think M5Stack is offering the preinstalled ESP-AT firmware binary on their website. That said you could try to configure and compile the ESP-AT firmware yourself by following the steps outlined here and here. Thanks Felix

@happyuser said in M5Dial generate interrupt from RTC?: I assume your conclusion is then also : no wake-up with RTC interrupt? Uhm no, or yes.... maybe.... depending of how you define "wake-up"🤔 ☺️ When Q3 goes on the hole board including the ESP32 is switched on so in my book the RTC can "wake up" the hole board. Of course you could say that this is more like "switching on" than "waking up". But in fact, when ESP32 is in its "native" deep-sleep the main CPU is also effectively switched off which means it needs to boot completely from scratch when it "wakes up" from that state. Now, it is correct that there are some build in features to test for the reason of the boot and then have the program act on that, but that is actually also possible with the circuit M5Stack built. There is a signal called "wake" connected to GPIO42 which will indicate for the ESP32 whether it was started by the push button (S1) or by the INT signal from the RTC chip. I can only speculate in why M5Stack has chosen not to use the build in ESP32 RTC/deep sleep functionality but here is two reasons: If the board as a hole needs to have a very low power consumption in (deep)sleep mode it is not enough to just have ESP sleep there are other chips or circuits that may still consume "a lot" just by having Vcc applied. So you need the MOSFET switches any way for a "good sleeping" board and the BM8563 seems to consume less than the ESP32 built-in RTC about ~2-3µA vs 10µA

@shadowdoggie Same doubt here. Did not find any UIflow2 hardware driiver for this unit. Is there an example code availabe for UIflow, or uPython?

@ajb2k3 Sure, here it is: Here is the full example for all ESP32s using the OV2640 camera in Arduino IDE (in the IDE board selection choose M5Stack UnitCamS3) Remember to edit the .ino file to include your WiFi credentials! The full sketch is here:  https://github.com/espressif/arduino-esp32/tree/cf448906b3836fbe9368934713b697469254c62f/libraries/ESP32/examples/Camera/CameraWebServer You can choose CAMERA_MODEL_ESP_EYE, and apply a little tweak in camera_pins.h like this:  https://github.com/m5stack/UnitCamS3-UserDemo/blob/main/firmware/src/hal/cam/camera_pins.h#L21 Also in the library used in your sketch app_httpd.cpp I had to change Line 77 from ('1" enabled) to ('0' not enabled ) #define CONFIG_LED_ILLUMINATOR_ENABLED 0 Successful upload serial output reads like this: 20:48:24.952 -> E (516) esp_core_dump_flash: No core dump partition found! 20:48:24.952 -> 20:48:24.952 -> ...... 20:48:24.952 -> WiFi connected 20:48:24.952 -> Camera Ready! Use 'http://192.168.0.37' to connect

It is possible as the stamp IO is a reprogrammable STM32f03

@falbriard I have been testing LoRa with Meshtastic lately using ESP32 boards (Heltec and Lilygo) and am looking to try now with M5. Built into the platform is support for environment sensors, other may need a bit of work to add (which is what I am hoping to do). I have a test mesh of 6 nodes, and only 1 is connected to my WiFi. Each node sends telemetry data with is read by the one (on WiFi) which in turns sens the message to an MQTT server. I then use Node-Red to process and push write the data into MongoDB. LoRaWAN uses LoRa to communicate with the gateway, so as long as it is reachable by the sensor you should be able to get your data. The LoRaWAN gateway does the bit of connecting your sensors to the cloud/network where you can access them. HTH.

Hello @felmue the Grove2Dupont Cables arrived today. I tried it with your example and all LEDs can be addressed and light up. Thank you very much for the great help! I do have some additional questions about the Pb.Hub and the VH3.96 Module in combination with my project. Should i open another thread for it? Greetings icemen

Link to the example? It probably use multiple I2C hubs.

Thnx, a threshold is exactly what I used as a workaround for know. Just wanted to ensure I'm not missing a point here.

@ghettokon Sounds like you have an 'audio curve' non-linear volume control pot! If it is a linear pot, then you either use a voltage divider or add resistors to the top pin or bottom pin as required to get centre. If 'volume control pot' then you will have to characterize the signal in your code.

@teastain - thanks! The end-use is a bird feeder that classifies the birds it sees. Something like this: https://www.birdfy.com/products/birdfy-feeder Not planning on training a model for the UnitV2 - the out of the box Yolo and Nanodet models recognize "bird" as a class. Idea is to capture an image when it sees bird and then send it to a server via wifi for species-level identification using a finer-grained classifier. Will put the unit to sleep at night. Thanks for pointing me to the overheating issue. That may sink the selection of these cameras for this use.
