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

Change Brightness |
SceOledForDriver
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).
