NAME
ssdfb -- OLED/PLED framebuffer device driver
SYNOPSIS
options FONT_SPLEEN5x8 ssdfb* at iic? addr ? ssdfb* at iic? addr 0x3c ssdfb* at iic? addr 0x3d flags 0x102 ssdfb* at spi? slave ? flags 0x105 wsdisplay* at ssdfb?
DESCRIPTION
The ssdfb driver provides wsdisplay(4) support for OLED/PLED framebuffer modules based on one of the following controller chips: Solomon Systech Ltd SSD1306 Sino Wealth Electronic Ltd SH1106 Solomon Systech Ltd SSD1322 Solomon Systech Ltd SSD1353 The following products (controller + panel assemblies) are supported: 0x01: Generic SSD1306 modules using default settings 0x02: Generic SH1106 modules using default settings 0x03: Adafruit Industries, LLC product 931 (128x32) 0x04: Adafruit Industries, LLC product 938 (128x64) 0x05: Generic SSD1322 modules using default settings 0x06: Generic SSD1353 modules using default settings 0x07: Display Elektronik GmbH DEP 160128A(1)-RGB The flags value can contain one or more of the following, bitwise OR'ed: 0x0??: Exactly one product id from the above list 0x100: indicates that the display is mounted upside down and flips the screen 0x200: enable inverse video 0x400: forcibly attach as console On most displays, the contrast setting can be adjusted with the wsconsctl(8) program.
EXAMPLES
To attach an SSD1322 display using the 4-wire spi(4) interface on an All- winner A20 ARM single board computer, the following Device Tree overlay can be used: &spi0 { ssdfb@0 { compatible = "solomon,ssd1322"; reg = <0x00>; dc-gpio = <0x10 0x07 0x02 0x00>; status = "okay"; }; }; To attach an SSD1306 display using the iic(4) interface on the same board, use: &i2c2 { ssdfb@3c { compatible = "solomon,ssd1306fb-i2c"; reg = <0x3c>; status = "okay"; }; };
