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

int SceOledForDriver_2F0C4B67_send_cmd(u8 cmd, void *buffer, int size);

sceOledGetBrightnessForDriver

Version NID
3.60 0x43EF811A

Get the wide brightness value (0-65536). 

int sceOledGetBrightnessForDriver(void);

sceOledDisplayOnForDriver

Version NID
3.60 0x4C7836C7 
int sceOledDisplayOnForDriver(void);

SceOledForDriver_6B1E0B52_oled_enable

Version NID
3.60 0x6B1E0B52

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

int SceOledForDriver_6B1E0B52_oled_enable(void);

SceOledForDriver_9F4ABDDC_get_status

Version NID
0.940-3.60 0x9F4ABDDC

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

int SceOledForDriver_9F4ABDDC_get_status(void);

sceOledDisplayOffForDriver

Version NID
3.60 0xBC84602E 
int sceOledDisplayOffForDriver(void);

sceOledGetDDBForDriver

Version NID
3.60 0xC9D5987C

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

int sceOledGetDDBForDriver(unsigned short *supplier_id, unsigned short *supplier_elective_data);

sceOledSetDisplayColorSpaceModeForDriver
