### Display
|
|
|
The NVS parameter "display_config" sets the parameters for an optional display. Syntax is
|
|
|
```
|
|
|
-I2C,width=<pixels>,height=<pixels>[address=<i2c_address>][,HFlip][,VFlip][driver=SSD1306|SSD1326|SH1106]
|
|
|
-SPI,width=<pixels>,height=<pixels>,cs=<gpio>[,speed=<speed>][,HFlip][,VFlip][driver=SSD1306|SSD1326|SH1106]
|
|
|
+I2C,width=<pixels>,height=<pixels>[address=<i2c_address>][,HFlip][,VFlip][driver=SSD1306|SSD1326[:1|4]|SSD1327|SH1106]
|
|
|
+SPI,width=<pixels>,height=<pixels>,cs=<gpio>[,speed=<speed>][,HFlip][,VFlip][driver=SSD1306|SSD1322|SSD1326[:1|4]|SSD1327|SH1106][SSD1675]
|
|
|
```
|
|
|
- VFlip and HFlip are optional can be used to change display orientation
|
|
|
- Default speed is 8000000 (8MHz) but SPI can work up to 26MHz or even 40MHz
|
|
|
+- SSD1326 can be used with bit depth of 1 (mono) or 4 (16 gray levels)
|
|
|
+- SSD1675 is experimental and e-ink are not suitable for that type of display anyway due to their very low response time
|
