Trying to get i2c working on ESP8266 SDK with the ESP-01 board

[scotnewon96]

Im trying to write to a slave device using the SDK with the small ESP-01 chip. I modified the example and read through the documentation but still dont seem to see chatter on the two pins (GPIO 0 and GPIO 2). I'm using a logic analyzer to confirm ACK's and all but dont see anything at all. I debugged the driver and I see it timing out at a certain point waitig for an ACK but the lines are silent. Im thinking maybe its not using the two pins i chose correctly? Heres the code if anyone can point me to what I may be doing wrong.

Could this example help? https://github.com/espressif/ESP8266_RT ... herals/i2c

Sorry for the late reply, I am getting back into the swing of things. I've worked with I2C and am on SKYPE GMT-8 @ Desert Computer Agents. Let me know if your still having issues and Ill take a peek with you, I worked with I2C with a pin expander to control an LCD screen in the past.

Just come back here and post the solution once we solve it.

*Update* Also, I don't see your code attached.
