Re: Problem reading I2C sensor

Hi Aveave,

do you have a logic analyzer to see whats going on?
In some cases my I2C still gets stuck on the esp32 in combination with the sensor but i hope we can get it running for you.

Regards,
Markus

Re: i2c randombly fails

Hi, i really hoped that this fix is going to help me with my I2C problems (mainly the SCL gets stuck or keeps clocking forever sometimes in the first seconds after a power-on, only way to recover is a module reset). Once the I2C bus works for the first couple of seconds it seems to be stable for a l...

Re: Problem reading I2C sensor

After I had to take care of many other things in the last weeks and I got the sensor to work with a very simple bitbanging I2C driver (got it up and running on second try), I had some time to get the sensor working with the I2C driver of the IDF today. WiFive´s hint was correct, I changed the timeou...

Re: Problem reading I2C sensor

Thanks for your replies! Unfortunately even with the new knowledge about the ACK/NACK bit nothing has changed. I can reproduce the I2C error when running in release config but i´ve already been using the debug config all the time. Do you know if clock stretching is already working correctly on the E...

Re: Problem reading I2C sensor

Hey guys, thanks for your replies! After the correct usage of the Ack/Nack bit when reading back data, my results look a bit better. After some attempts and trying to stick to the measurement triggering example on page 5 of the sensor´s datasheet, the following code works best so far even if it seem...

Problem reading I2C sensor

Hello, i´ve been trying to get data out of a SDP600 differential pressure sensor from Sensirion for a couple of days now. The problem is that i can not read back data at all. The sensor is wired correctly and answering a scan request. To start the transmission of measuring data, you have to write a ...

ESP32 Mongoose webserver serving static files

Dear community, my name is Markus and I´m quite new to the ESP32 and its programming. At the moment I try to expand the Mongoose webserver example from https://github.com/nkolban/esp32-snippets/tree/master/mongoose/webserver to be able to serve other static files than my "index.html" but I dont get ...
