The "Display Example I2C" board config is broken. Do not use it. Instead, under the "deauther config" menu, select the default "NodeMCU" at the top, and then in A_config.h, manually copy everything from the "Display Example I2C" section to the top, outside of its "#if defined" group.

Just struck this issue.

disabling #define DISPLAY_EXAMPLE_I2C
and adding the following directly under #define NODEMCU

#define SSD1306_I2C
#define I2C_ADDR 0x3C
#define I2C_SDA 5
#define I2C_SCL 4

Works fine.

Issue seem to be that LED_NEOPIXEL_GRB is enabled in the DISPLAY_EXAMPLE_I2C and it uses to many resources causing watchdog to reset
