ssd1306 oled on i2c not showing up ( esp Azure iot kit ) about esp-iot-solution HOT 14 CLOSED

@InfiniteYuan1 I did open a case: #49 this seems to be pattern of an issue with the OLED/ss1306 OR with the esp32_azure_iot_kit example. Please have someone look into it as these tests are crucial to some of our work related releases.

@InfiniteYuan1 new issue is what i created.

Board : Esp Azure IOT kit
when i scan for i2c device using i2ctool, i am getting this now

esp32> i2cconfig --port=1 --freq=100000 --sda=25 --scl=26

Hello,
i am using the same board, and i want to have access to the sensors' data. I am trying to make it through the I2C bus. Although, the scanning proccess on I2C does not detect any device.
I am coding in arduino IDE. Is there any advices?
Thank you!

@ChristosPalisidis i had exactly the same issue. If using esp-idf there will not be any issues, device works properly.
Have you set the SDA and SCL pin correctly?

from esp-iot-solution.

Yes, i print the SDA and SCL pins so as to be sure, and i use these printed pins for the I2C interface.
I made a lot of progress and development of my project, working on ARDUINO IDE, so a migration to ESP-IDF at this point, would be very time consuming. Is this possible to continue with ESP-IDF and use my current work as component, or something like that?
Thank you for your response @manjuk41 !

@ChristosPalisidis I don't know.

Hi, I have this board and I am having the same issue. I am using the sample as is without any changes as yet but I am planning to enhance this application to write to Azure IoT using the esp-azure sdk. But before I do this I need to ensure that the board and all sensors are working correctly. Looking at the monitor the application is working correctly and I can see the data being captured from sensors and shown in monitor. The issue is that it is not showing up on the OLED. Note before I used the example from this repo the OLED was working and displaying data/output.

Running i2cdetect gives me:

I can set SDA and SCL again but I set them initially.

from esp-iot-solution.

I personally figured it out. It was the pins settings finally @manjuk41 . I will be more carefull with the datasheets next time!

from esp-iot-solution.

@ChristosPalisidis I wish mine was that easy. Pins were set correctly. Hoping they review this issue and/or mine for resolution.

from esp-iot-solution.

@tawalke Same issue here. Pins are all set correctly.
Do you have any idea on how to debug with a logic analyzer?
