SH1122 I2C

[JasminMelni1990]

I got the following display with an SH1122 I2C driver and i need help running it.

I can only find SPI in the u8g2 library but not for i2c. What am i missing?
I'm using arduino pro micro for testing

Did you check https://github.com/olikraus/u8g2/wiki/u8g2setupcpp ?

I did but i can't really make much sense of it since i'm fairly new to Arduino.

U8G2_SH1122_256X64_1_HW_I2C(rotation, [reset [, clock, data]]) [page buffer, size = 256 bytes] i probably need this right?
if so how do i add it to the code?

You could look for a HW_I2C line in one of the examples. Uncomment this line and replace the constructor name with U8G2_SH1122_256X64_1_HW_I2C

So, for example this line:

u8g2/sys/arduino/u8g2_page_buffer/HelloWorld/HelloWorld.ino

Line 84 in 7014e1d

//U8G2_SSD1306_128X64_NONAME_1_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE);

becomes

U8G2_SH1122_256X64_1_HW_I2C u8g2(U8G2_R0, U8X8_PIN_NONE);

Also remember to activate 16 bit mode for your 256x64 display:

u8g2/doc/faq.txt

Lines 163 to 169 in 7014e1d

	Q: How to activate 16 Bit mode?
	A: Search for the line
	//#define U8G2_16BIT
	in "u8g2.h". Uncomment this line:
	#define U8G2_16BIT
	The file "u8g2.h" is located in "/libraries/U8g2_Arduino/src/clib" inside your default
	sketch folder.

That worked! Thank you very much!!
