library not working

[ThoSanLinhHon]

I tried with arduino nano and ide 1.8.12 but the module does not work. Same circuit, earlier I tried with adafruit's library and it worked fine. I hooked up the OE pin to GND so I left out setupOutputEnablePin and enableOutputs. Because I made a pcb, I can't connect the OE pin to another digital pin. Is that the cause?
I'm glad this library doesn't conflict with the SSD1306 library but it doesn't work. Hope you help me!

Hi. Can you be more specific about what example code you are trying and what problems you are having? You should still work if your OE pin is tied to ground. It is ok to leave out the setupOutputEnablePin and enableOutputs lines. Are you sure you are using the correct device_address? There is a fast mode plus option for the i2c (two-wire interface) perhaps you could try enabling that to see what it does. ThoSanLinhHon ***@***.***> writes:

I set the address as 0x40.
Initially, I just used the ChangeOnTimeandOffTime sample example, but used constants instead of variables.
I will upload the code later. Thanks!
