7-Segment Backpack with Olmex ESP8266-EVB

by abarrow on Wed Nov 08, 2017 10:52 am

Has anyone been able to get the 7-Segment backpack to work with a Olmex ESP8266-EVB? I tried to move working (on an ESP-12E) code over to the Olmex ESP8266-EVB and everything just stopped - the display doesn't light at all. According to the serial monitor, the code is still working. I then tried the sample code from Adafruit, and the same result.

If I load something like ESP-Easy on the Olmex, it does detect the I2C device.

Is there something different about the Arduino IDE and the Adafruit header files that might be causing this? Any suggestions for further troubleshooting? Maybe power?
