Hi all, I am somewhat confused at the moment. Despite the fact that I have a good knowledge about RTOS and Arduino platform I can't figure out how to use I2C wire library with RTOS/ESP-IDF. If for example I have bought a sensor which has arduino wire based API and does not have ESP-IDF based I2C API...

Hi, I am sharing the issue I faced to build the BLE application in hope that it might be useful to someone else with the same issue While I was running the command to build the project I got the error as specified here. idf.py build /user/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp...

As far as I could undestand from the first look is that there are "Undefined reference", so make sure that both .h and .c/.cpp files exists which make is able to find while building the project.!

Hi, I was trying to interface DPS310 sensor from Infineon with ESP8266 but it is not working as expected. The I2C interface is fetching correct data for the sensor ID but it fails to provide right data for temperature. I have already decided to not work with this sensor but still if someone could ha...

I have a question regarding 2's complement values which I get from I2C sensor. I am new to ESP and maybe the question might look a bit strange but I am facing this problem. I have a pressure sensor from Infineon DPS310. There are two's complement values in 12 bit and some are in 24 bits. I want to p...

Thanks for the reply.
One more question. Suppose I want to try the I2C sensor BME280 from Bosch. From the I2C API what I can see is that there are only read-write operations available.
So is it that I have to look for what registers to configure, write and read from the sensor?

Hi, I have a question regarding making own code and upload it to ESP boards. I have already tried few samples like examples/peripheral/LEDC and ../GPIO , ../hello_world. and those worked like a charm!! Now, I want to try my own code for things like GPIO, I2C, SPI, BLE etc. I don't understand everyth...

Hi, Is this thread still alive? Did you find the solution? I have the same problem with Pico Kit v4 as the original poster of this thread. My Pico kit does a normal job when a sketch is uploaded to the board but when I disconnect the board and power it again with a USB cable I have to press the EN b...
