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

Version NID
3.60 0x0CC6BCB4
int sceOledWaitReadyForDriver();

Waits until the OLED has been initialized.

SceOledForDriver_26F9EEA8

Version NID
3.60 0x26F9EEA8
int SceOledForDriver_26F9EEA8_oled_disable(void);

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

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).

int sceOledDisplayOnForDriver();

sceOledGetDisplayColorSpaceModeForDriver

Version NID
3.60 0x4F8A1D4A
int sceOledGetDisplayColorSpaceModeForDriver(void);

SceOledForDriver_6B1E0B52

Version NID
3.60 0x6B1E0B52
int SceOledForDriver_6B1E0B52_oled_enable(void);

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

SceOledForDriver_9F4ABDDC

Version NID
3.60 0x9F4ABDDC
int SceOledForDriver_9F4ABDDC_is_disabled(void);

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

sceOledDisplayOffForDriver

Version NID
3.60 0xBC84602E
int sceOledDisplayOffForDriver();

sceOledGetDDBForDriver

Version NID
3.60 0xC9D5987C
int sceOledGetDDBForDriver(unsigned short *supplier_id, unsigned short *supplier_elective_data);

Returns the Device Descriptor Block (DDB), read with MIPI DSI command read_DDB_start (0xA1).

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).
