Converting an SPI OLED to i2c 2.42in. DIYmore SSD1309

[@howardtomlinson3871]

I was getting frustrated watching you do the soldering until I tried it myself. Those connections and that smd resistor are SO tiny, you did a great job 👍👍

Thank you, the clone of this screen had the resistors set for SPI but not the jumpers, adding the shorts to R15 and R13 in my case fixed my screen. When using with an ESP32 you also have to connect the RES pin to the ESP32 reset line, in the case of the dev board I have it's labeled as EN. Not 100% sure of this but I believe the CS pin is for chip select, so you can have 2 or more screens running on the same SPI Line, then you short to GND the CS line of the screen you want to use, then reset the screen and now you can use it. This may not work with some microcontrollers and is more of an educated guess..

Very nice and clear instructions! Those 2.42" OLED screens require a power on reset (just like on an Amiga), and the reset pin on Gotek board provides exactly that (as well as being for manual reset).

Thanks!

Very helpful......My OLED blinked once, showed my pattern. Then a wire to arduino RESET pin made it stay working.

VCC -- 10K -- Reset-- | 100nF | -- GND and no reset connection external is necessary

Thank you for confirming no external reset.

Thank you! This was mentioned nowhere else. Works great with the SSD1306 driver and pydPiper now.

27K and 10uF in my case were helpful

Thank you

Thank you for this intuitive video I managed to put working all my displays. Great

Where do i put the rst pin for a Raspberry Pi 3, and can I put a 0 Ohm resistor for r3. Also do I need to short R7 to CS for my Raspberry pi 3?

[@360Sebastian360]

Do you power your 2.42 inch OLED via 3.3 or 5 volt ?

[@HeyApos]

Thanks very much. Really saved my life :-)

Thank you! That helps a lot!

Can it display Chinese characters?
