I bought this LCD from taobao but I cant make it display anything, I tried tones of library for Arduino but still nothing happen. I also try to scan IIC but it return: No iic divice found. Try to use adress 0x3E but nothing happen too
Anyone has library that work with my LCD?
Driver IC is AIP31068
I'm using 5V for VDD
SCL and SDA connect directly or using 10k pull up resistor
Thank you for your recommendation, the first one I tried before, the second one I have just tried but it's not showing the meaningful character. However, it displayed some dot (so that the LCD is somehow respond).
Test with the I2C Scanner (from the Arduino IDE examples) to get the address confirmed.
The I2C scanner must find the display reliable before bothering with any library.
Can you please post a datasheet of the display to be able to check your wiring/jumpering?
10K pullups on SDA/SCL seems to be quite high. Where did you get the information from to use 10K?

I would also have thought that it is hopeless if the I2C scanner fails to detect anything.
You are clearly assuming that J4 can be left without a jumper if the PSB (Protocol Selection Bit?) is pulled high on the side bar. I can't see definitely if J4 was intended for a resistor or a direct solder bridge but it does look narrow for a resistor.
J2 and J3 are probably for the 3.3v option and should probably be in the original factory condition.

The iic scanner return no device. The pull up resistor I just added without any clues.

For the jumpers, I tried everything that I can do to check the LCD. But none of them ok. J4 the sellers said the LCD driver does have internal pull up, but I added 10k or directly connect, they are the same
