    SCE_OLED_ERROR_INVALID_BRIGHTNESS_VALUE = 0x803F0A02,

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

Cmd Size Buf Description
178 1 Unknown Unknown
249 1 or 22 Unknown, for example <0x01, 0xCFBE9F9F, 0xCBC2C9D7, 0xDEE3E1BB, 0xFAD3D0D6, 0x002FE6ED, 0x2F> (Little-Endian) Change Brightness

SceOledForDriver

ksceOledWaitReady

Version NID
3.60 0x0CC6BCB4
int ksceOledWaitReady();

Waits until the OLED has been initialized.

ksceOledForDriver_2F0C4B67

Version NID
3.60 0x2F0C4B67
int ksceOledForDriver_2F0C4B67(u8 cmd, void *buffer, int size);

Sends a command to the OLED.

ksceOledGetBrightness

Version NID
3.60 0x43EF811A
int ksceOledGetBrightness();

Get the wide brightness value (0-65536).

ksceOledDisplayOn

Version NID
3.60 0x4C7836C7
int ksceOledDisplayOn();

ksceOledDisplayOff

Version NID
3.60 0xBC84602E
int ksceOledDisplayOff();

ksceOledSetDisplayColorSpaceMode

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

ksceOledForDriver_E30604CC

Version NID
3.60 0xE30604CC

Dispatches the OLED cmd list (using ksceOledForDriver_2F0C4B67).

ksceOledSetBrightness

Version NID
3.60 0xF9624C47 (wrong nid?)
int ksceOledSetBrightness(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).
