Hello, I realize this topic is very old but I'm trying to compile the MultiApp Advanced firmware. I'm getting several compile issues:

src/Apps/WiFiWps/WpsConnect.cpp:30:12: error: 'struct esp_wps_config_t' has no member named 'crypto_funcs'

src/Apps/WiFiWps/WpsConnect.cpp:30:28: error: 'g_wifi_default_wps_crypto_funcs' was not declared in this scope

src/Apps/WiFiWps/WpsConnect.cpp:90:27: error: no matching function for call to 'onEvent(void (&)(arduino_event_id_t, system_event_info_t))'

src/Apps/WiFiWps/WpsConnect.cpp:90:18: error: invalid conversion from 'void ()(arduino_event_id_t, system_event_info_t)' to 'WiFiEventSysCb' {aka 'void ()(arduino_event_t*)'} [-fpermissive]

*** [.pio\build\esp-wrover-kit\src\Apps\WiFiWps\WpsConnect.cpp.o] Error 1

lib/ESP32Audio/src/AudioOutputI2S.cpp:190:10: error: 'i2s_write_bytes' was not declared in this scope

*** [.pio\build\esp-wrover-kit\lib803\ESP32Audio\AudioOutputI2S.cpp.o] Error 1

I did clone the git repo today, so everything should be up to date. Looks like I'm missing some library?

Thanks,
Brian

We use M5stack basic as our main controller, we can connect any camera. It only needs to adapt to the camera of StickV or UnitV to complete the recognition.

Hello @BM22

have a look at this example. It shows how to put 'Hello World!' onto the M5CoreInk screen.

Thanks

@ajb2k3
Thanks. I'm glad to join this forum!

How do i get the characters for my region such as the pound sign £ ?

Hello @Peter-Sain

most GPIOs on the ESP32 can be setup to do different things - so yes an no, GPIO32 and GPIO33 are not per se analog pins, but they can be if needed.

However the DS18B20 is a OneWire component which is a digital bus (and not analog).

I just ran a test (Arduino) with my M5StickPlus and either GPIO32 or GPIO33 can be used just fine to talk to a OnWire DS18B20 temperature sensor.

Did you connect a 4.7 k resistor between VCC and OneWire data line?

Could you share your code?

Thanks
Felix

@sconstan Hi, I was working on that. I have a version of CanAirIO Firmware working with Home Assistant. And now CanAirIO Firmware support M5StickCPlus M5AtomLite and M5CoreInk. Maybe I think is possible that works with M5 Core2

Home Assistant Support Home Assistant first release. PR #153 Anaire improvements and clouds refactors battery level primitives on BLE, InfluxDB and MQTT clouds new BMP680 sensor and some Sensorslib improvements Refactor main_value and device_type from Sensorslib

On one hand things are going great and i'm learning a lot on the way.

On the other hand i realized that reading the Position of a servo, like it is shown in the Arduino example-code of the Motion Kit, is not sufficient as sensory-data (it just represents the applied position/velocity). Due to physical interaction i want to track the real, measured angle to compare with the desired.

So in the long run i'll use servos with Position-Feedback to read the angle from the additional wire. As noob its hard to compare any specs, but the "KST MR320 PF" may be appropriate as replacement (still confused about the min and max angle it can take, it must not turn infinite, but a range of at least 270° would be great).

For the current prototyping, i will extend each servo with an Angle-Module (potentiometer), combined with a PbHub and connected to the Motion-Kit. This may be a bit overkill (in cables and weight), but cheaper and sufficient to have a nervous-system as processing-inputs.
