had a back-up file with extension "main-Copy.cpp". Got the same error, but deleting this file fixed the problem!

Hi, I have finally had it working to my needs. Here is how I did it (hope it would save somebody few hours): I ran the wifi + i2s communication on the main thread, where as I ran i2C comm on separate task. This seems to be working I also noticed that most of the issues that I encountered were caused...

Hi, Using ESP-IDF with ESP32-WROVER kit with jumper wires. I am running an accelerator and microphone, using freeRtos task. The sensors work fine when only one of them being used. But the problem occurs when I try to do parallel task utilizing dual cores. I2C communication stops working while i2s ke...

Thank you for your response. Here is the configuration: I2C Device: 3 axis accelerometer Analog device: analog Microphone Board: ESP32 dev kit Arrangements: on the breadboard with jumper wires I2C device drawing power from the ESP32 dev module, and communicating via pin via 21 and 22 (SCL, SDA). Ana...

First of all I am new to electronics. I am using ESP32 dev kit and trying to communicate with an i2c sensor and an analogue sensor. I am able to communicate both devices. I am using freertos Task to gather output running on parallel threads on two cores of esp32. But I moticed that as the i2c commum...

Hi, I am trying to use WiFiUDP class. When I try to send the data using the function wifiudp.write(buf, l), I get compiler error. Which says: error: macro "write" requires 3 arguments, but only 2 given wifiudp.write https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/src/WiFiUdp.h ...

Thank you for your reply. No I can see it.

Thank you, Please close this as solved.

Folks, I am a new member to this forum but I am experiencing long delays in my new post and replies published, is there any step I am missing here or it's generally slow to publish your thoughts/questions on this forum. I posted to two replies for my posts but all I get a message saying it would be ...

Thank you for your replies. I am working using esp-idf framework using eclipse in C++. So I would prefer in C++. I was able to hook up esp32 with the sensor and successfully run it via Areduino IDE and Arduino-esp32 core. I will look into the logic analyzer, if you look through the code I am assumin...

Thank you for your response onehorse and Kolban. Onehorse, I am trying not to use Arduino library for my project as I am not sure what works and what does not work. I don't know where I would get stuck using Arduino library for esp32. I also looked into Arduino Wire.h to figure out where I could be ...
