Programming Avr328 SSD1306 OLED Inside of Arduino Without Arduino IDE With MysmartUBS Light

• I asked myself if there is a library for programming the avr328 to control the SSD OLED 1306 with i2c.
• Yes there is one, or there are maybe some more.
• so today I randomly picked one library and tried to run it:

https://github.com/Matiasus/SSD1306

• check the datasheet of arduino
• check the connection of OLED
• connect scl and sda and use 2 pull up resistors and gnd and vin
• connect the my smart usb to the icsp = in circuit serial programming - pin
• the nose is directed inside the arduino
• connect the arduino board with USB

• Goto: https://github.com/Matiasus/SSD1306
• clone the repository
• open it with visual studio code

the author gives two hints depending of what OLED you are using you have to change following lines:

• 128x64 version
• command argument SSD1306_SET_MUX_RATIO set to 0x3F (ssd1306.c)
• command argument SSD1306_COM_PIN_CONF set to 0x12 (ssd1306.c)
• END_PAGE_ADDR set to 7 (ssd1306.h)
• 128x32 version
• command argument SSD1306_SET_MUX_RATIO set to 0x1F (ssd1306.c)
• command argument SSD1306_COM_PIN_CONF set to 0x02 (ssd1306.c)
• END_PAGE_ADDR set to 3 (ssd1306.h)

• In the make file change following line to:

# AVRDUDE PROGRAMMER

AVRDUDE_PROG = stk500

• open a terminal and press make
• a hex file will be created
• for me make flash didnt work but you can do it of course or use for example avrdudess :
