为SSD1306 i2c驱动程序

亲爱的先生,
我只是想init OLED SSD1306司机,在外设使用i2c演示项目,但是它不工作,i2c频道只发送0 x00无论我怎么改变代码。请帮助。

代码:
空白demo_i2c_init(空白)
{

静态常量i2c_config cfg = {
。speed = HW_I2C_SPEED_STANDARD,
.mode = HW_I2C_MODE_MASTER,
.addr_mode = HW_I2C_ADDRESSING_7B,
};

hw_i2c_init (HW_I2C1 cfg);

将srand (OS_GET_TICK_COUNT ());

如果(config_need) {
int犯错;
i2c_device开发;

dev = ad_i2c_open (SSD1306);

呃= SSD1306_power_on (dev);
如果(err) {
printf(换行符”错误SSD1306_power_on 0 X % X”,错);
}

ad_i2c_close (dev);
config_need = false;
}
}
int SSD1306_power_on (i2c_device dev)
{
/ / OS_ENTER_CRITICAL_SECTION ();
ad_i2c_device_acquire (dev);
SSD1306_write_i (dev, 0机加区);
0 x00 SSD1306_write_i (dev);
SSD1306_write_i (dev, 0 x10);
0 x40 SSD1306_write_i (dev);
SSD1306_write_i (dev, 0 xb0);
SSD1306_write_i (dev, 0 x81);
SSD1306_write_i (dev, 0 xaf);
SSD1306_write_i (dev, 0 xa1);
SSD1306_write_i (dev, 0 xa6);
SSD1306_write_i (dev, 0 xa8);
0 x0f SSD1306_write_i (dev);
SSD1306_write_i (dev, 0 xc8);
SSD1306_write_i (dev, 0 xd3);
0 x00 SSD1306_write_i (dev);
SSD1306_write_i (dev, 0 xd5);
SSD1306_write_i (dev, 0 x80);
SSD1306_write_i (dev, 0 xd9);
0将SSD1306_write_i (dev);
SSD1306_write_i (dev, 0 xda);
0 x02 SSD1306_write_i (dev);
0 xdb SSD1306_write_i (dev);
0 x40 SSD1306_write_i (dev);

SSD1306_write_i (dev, 0 x10);
SSD1306_write_i (0 xaf);
ad_i2c_device_release (dev);
/ / OS_LEAVE_CRITICAL_SECTION ();
返回true;
}

静态int SSD1306_write_i (i2c_device dev uint8_t val)
{
uint8_t op [2] = {0 x12, val};

返回ad_i2c_write (dev, op, sizeof (op));
}
