Hello i was hoping someone could help me with connecting a ESP32 Wrover to an 1.5" 128 x 128 OLED just to display temps ect.
Im not sure if i need to use SPI Master or just use the SSD1351(SPI) component or both.
In the component properties of the gLCD_SSD1351_SPI1 which is what im thinking it need im not sure how to configure the connections and also it appears flowcode has a labeling issue on the reset connection as when you hover over it, it says Instruction/Command pin connections not "reset".
Could some one please help me with the code needed just to print a string to the OLED display

Hello,
Please can you post your program so far and I'll have a quick look for you.
Also thanks for the info regarding the tooltip on the reset pin.

Re: ESP32 OLED display via SPI
Hello,
Pins GPIO34 to 39 are input only and so are not capable of digital output. Can you reconnect the display to other Pins, e.g. on PORTA or PORTB 0 to 1.

Re: ESP32 OLED display via SPI
Hi guys, can anyone educate me on SPI 4 Wire & 8080 SPI for talking to OLED Displays?
I ordered 4 @ 256 x 64 OLED Displays ( Link Here ) from China, and asked for 4 Wire SPI as this is how the Tutorial i was following is configured, but the displays have arrived configured for 8080 Parallel, so i am trying to decide if i should re-solder the board, send them back (painful) or try to use them how they are configured.
I am using a ESP32 and the OLED controller is a SSD1322.
This is what i am working on copying:

Im not educated enough to know if how the displays are configured at the moment is suitable for the project, if it is slower than 4 Wire SPI, etc.
Any advice would be greatly appreciated.
Thanks
