Hi Wayne_seltzer
I figure out the problem.
Please review “https://wiki.seeedstudio.com/Grove-OLED-Display-0.96-SSD1315/”, there is a “FAQ” mention this problem.
if you just use OLED without other modules, you need to replace “U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8;” with “U8X8_SSD1306_128X64_NONAME_SW_I2C u8x8(/* clock=/ SCL, / data=/ SDA, / reset=*/ U8X8_PIN_NONE);”.
if you use OLED connect with other modules, please put “U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8);”.
Best regards
Fenyi
