Hi, are you using the code and schematic exactly as shown in this repo, or are you wanting to make some changes or adaptations?

Looks like that library has changed since I last used it. No longer accepts 4 parameters, only 3. I think that last parameter is buffer size, which seems to default...

Why are you using attiny85? I used one in this project because my windspeed, direction and rain sensors are "dumb" and need continuous monitoring: counting pulses etc. If I used...

@gunaone that's just a link to a Google search. Post a link to your display and adaptor. If you are indeed using the DIY MORE adaptor and a ks0108 based...

Run the "i2c_scanner" sketch from the examples menu in the Arduino IDE. Does it detect the adaptor? What address does it detect? Run the "LCD_Demo_Using_I2C.ino" example sketch from this library...

Good to hear that the i2c scanner sketch works and reports the correct address. Did you solder the adaptor to the display correctly? Did you check for bad solder joints?...

Is it possible that your LCD is an ST7920 model? The adaptor is designed for KS0108 model of LCD. I do not know if this adaptor and library will work...

> so i use 4 pin wire(RS, R/W,E,RST) and is runing ok with "u8lib" Are you saying that the LCD works correctly using SPI bus instead of i2c adaptor? If...

Same for me. Install fails with Bookworm but succeeds with Bullseye
