struct SceOledCmd {
    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 || next_cmd->cmd == 255) {...} // End of queue

Available commands

249 1 or 22 Unknown, for example <0x01, 0xCFBE9F9F, 0xCBC2C9D7, 0xDEE3E1BB, 0xFAD3D0D6, 0x002FE6ED, 0x2F> (Little-Endian) Change Brightness

SceOledForDriver

sceOledWaitReadyForDriver

Version NID
3.60 0x0CC6BCB4 
int sceOledWaitReadyForDriver();

Waits until the OLED has been initialized.

SceOledForDriver_2F0C4B67

Version NID
3.60 0x2F0C4B67 
int SceOledForDriver_2F0C4B67_send_cmd(u8 cmd, void *buffer, int size);

Sends a command to the OLED (via SPI).

sceOledGetBrightnessForDriver

Version NID
3.60 0x43EF811A 
int ceOledGetBrightnessForDriver();

Get the wide brightness value (0-65536).

sceOledDisplayOnForDriver

Version NID
3.60 0x4C7836C7 
int sceOledDisplayOnForDriver();

sceOledDisplayOffForDriver

Version NID
3.60 0xBC84602E 
int sceOledDisplayOffForDriver();

sceOledSetDisplayColorSpaceModeForDriver

Version NID
3.60 0xDABBD9D3 
int sceOledSetDisplayColorSpaceModeForDriver(int mode);

SceOledForDriver_E30604CC

Version NID
3.60 0xE30604CC 
int SceOledForDriver_E30604CC_dispatch_cmd_list(void);

Dispatches the OLED cmd list (using ksceOledForDriver_2F0C4B67).

sceOledSetBrightnessForDriver

Version NID
3.60 0xF9624C47 
int sceOledSetBrightnessForDriver(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).
