You are right. The ESP32 does have a MPU, but it is somewhat limited and not supported in esp-idf at this moment.
Hello,

So would you please let us know like when it can be available into IDF to use it?

getting wrong distance value while using HC SR04 Ultrasonic Sensor with ESP323

Hello, Hope you guys are doing well into COVID-19. We are using Ultrasonic Sensor HC SR04 with ESP32-WROVER-I module to measure object distance. We have ported with ESP32 IDF 3.2 Stable Release and it works fine into normal condition. But when we run test continuously at every 2[*]0 msec interval to...

Re: GPIO Interrupt on specific core is not working

Because I believe ISR is highest priority which can be executed first on core 0 if available otherwise on core 1 if no any room is available. Just to correct this: No, ISRs are always executed on the core where they are allocated/initialized. However ISRs can wake up a task (using semaphores, queue...

Re: ESP IDF: Station + soft-AP (WIFI_MODE_APSTA) There is no working example - why? Where is?

How should this be handled if the station ssid and password is unknown? I have set up my ESP32 to run in AP mode and allow entering config from a http server it generates (this is done). I do not require both STA and AP modes at the same time, so some explanation on how to bring the wifi down then ...

Re: ESP IDF: Station + soft-AP (WIFI_MODE_APSTA) There is no working example - why? Where is?

I think that what is missing here is the fact that the ESP32 has only 1 radio and 1 antenna. Therefore, the channels selected for STA Mode and AP Mode have to be the same. Different Channels will not work. The same goes for ESP NOW/MESH implementations. My suggestion would be that, on start-up, def...

Re: Failing EMC test (ADC channels not stable)

@WiFive in regards to isolating RTC functions: No, haven't tried that since if we only have something connected to ADC 0 I still have a problem (but you are right that we might be able to get rid of the cross talk from other channels by trying that). @fly135 in regards to impedance: We have a volta...

Re: Dialogflow gRPC Support

hi, please, i can use gRPC protocol to send data to Visual Studio gRPC server (c#) ?? So it looks like the ESP Voice Assistant SDK uses Google Dialogflow through the gRPC hooks. Is there any way we could get a generic example of using gRPC in the IDF? Or maybe someone out there has some code they'd...
