in my current project I have only 2 wires left to be used for an Oled display. So i2c is the way. I killed my last SH1106 Oled while installing it and I ordered a new one. This time I went for a SDD1306 1,54 inch Oled only to find it just offers SPI and can´t be used in i2c mode.
While I was trying to google for a i2c to SPI bridge device I remembered that I have a couple of ATTiny13. Had them for years and never used them.
Is there a way to have an ATTiny13 recieve the i2c and translate it to SPI?
I have found this https://github.com/bunnie/i2c-spi-bridge
which uses an ATTiny85. If this could also work with a 13 could someone tell me how to connect it? I have never worked with it and can´t make heads or tails from the example code.
Alternatively: could I employ an Arduino Nano to do the conversion?
P.S.: I don´t need a super fast interface. The Oled will be used as a time and date display build into a wooden frame
