Types
A  is a contiguous array of   of different sizes. To get the next  of a queue, do:

sceOledWaitReadyForDriver
Waits until the OLED has been initialized.

SceOledForDriver_26F9EEA8_oled_disable
Disables the OLED by clearing the GPIO bus 0 port 0.

SceOledForDriver_2F0C4B67_send_cmd
Sends a command to the OLED (via SPI).

sceOledGetBrightnessForDriver
Get the wide brightness value.

SceOledForDriver_6B1E0B52_oled_enable
Enables the OLED by setting the GPIO bus 0 port 0.

SceOledForDriver_9F4ABDDC_get_status
Returns the OLED status by reading the GPIO bus 0 port 0.

sceOledGetDDBForDriver
Returns the Device Descriptor Block (DDB), read with MIPI DSI command.

SceOledForDriver_E30604CC_dispatch_cmd_list
Dispatches the OLED cmd list (using SceOledForDriver_2F0C4B67_send_cmd).

sceOledSetBrightnessForDriver
Set the brightness (brightness needs to be in the range ). means screen turned off,  means screen dimmed (like if you wait for a long time without touching your screen).

The brightness has actually 17 different values: 1 special value for, and 16 different values for the rest.

SceOledForDriver_ED2D6F19_set_status
Used to enable or disable.

SceOledForDriver_DDB1412B_reset
Used to reset.
