hello,
Can someone make life easy and explain what pins of the display go where in esp8266.
I have read a lot, used the examples provided by the library and contacted the supplier "SB" that makes thing "intelligent" but nothing seems to work.
I really wonder why can't we have standard labeling on all products.
please help
You have an "SPI" OLED. The sketch (and sometimes the library) will show the I/O pins... so post your sketch here (or inspect it yourself).
Here is an example of part of a sketch using an SPI OLED...
// Declaration for SSD1306 display connected using software SPI (default case):
//#define OLED_MOSI 9
//#define OLED_CLK 10
//#define OLED_DC 11
//#define OLED_CS 12
//#define OLED_RESET 13
//Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT,
From this page
GND is the ground pin.
VCC is the power supply for the display, which we connect to the 5V pin on the Arduino.
CLK / D0 is the SPI Clock pin. It’s an input to the chip.
MOSI / D1 is the Serial Data In pin, for data sent from your microcontroller to the display.
RES (Reset) pin resets the internal buffer of the OLED driver.
DC (Data/Command) is used by the library to separate the commands (such as setting the cursor to a specific location, clearing the screen, etc.) from the data.
CS is the Chip Select pin.
And I guess...
BL is BackLight or "anode"
It was much simpler before the "wokerati" decided that MISO, MOSI and SS were naughty words.
Now we have an unholy mixture of MISO/MOSI/SS/SIMO/SDO/DO/DOUT/SO/MTSR/SOMI/SDI/DI/DIN/SI/MRS/nCS/CS/CSB/CSN/nSS/STE/SYNC to deal with
Here is another reference clip from this linked page...
If you’re using an OLED display with SPI communication protocol, use the following GPIOs.
GPIO 14: CLK
GPIO 12: MISO
GPIO 13: MOSI
GPIO 15: CS
Thank you guys for your reply.
From all the information i gathered and the.links you provoded i assume the connection should be as follows:
GND >> GND
VCC >> VCC
DIN >> ????
CLK >> GPIO0 (D3)
CS >> GPIO 15 (D8)
DC >> ????
RST >> RST
BL >> ????
Can someone help solving for the ????
