    unsigned char cmd,
    unsigned char size,
    unsigned char buf[size]
}

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

struct SceOledCmd *cur_cmd = ...
struct SceOledCmd *next_cmd = &(cur_cmd->buf) + cur_cmd->size;

if (next_cmd->cmd == 0) {...} // End of queue

SceOledWaitReady

Version	NID
3.60	0x0CC6BCB4

int SceOledWaitReady();

Waits until the OLED has been initialized.

SceOledGetBrightness

Version	NID
3.60	0x43EF811A

int SceOledGetBrightness();

Get the wide brightness value (0-65536).

SceOledSetBrightness

Version	NID
3.60	0xF9624C47

int SceOledSetBrightness(unsigned int brightness);

Set the brightness (brightness needs to be in the range 0-65536). 0 means screen turned off, 1 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 brightness=0, and 16 different values for the rest (real_value=brightness/4096).

SceOledForDriver_2F0C4B67

Version	NID
3.60	0x2F0C4B67

int SceOledForDriver_2F0C4B67(u8 cmd, void *buffer, int size);

Sends a command to the OLED?

SceOledForDriver_E30604CC

Version	NID
3.60	0xE30604CC

Dispatches the OLED cmd list (using SceOledForDriver_2F0C4B67).
