enum SceOledError { SCE_OLED_ERROR_INVALID_BRIGHTNESS_VALUE = 0x803F0A02, SCE_OLED_ERROR_INVALID_READY_STATUS = 0x803F0A03, SCE_OLED_ERROR_NOT_READY = 0x803F0A04, SCE_OLED_ERROR_INTERNAL = 0x803F0A05 }; enum SceOledStatus { SCE_OLED_STATUS_NOT_READY = 0, SCE_OLED_STATUS_READY = 1, SCE_OLED_STATUS_ERROR = 2 }; 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)

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 |

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
).
