FAQ-按耳机hook键控制FM调频功能

耳机检测方式为ACCDET_SUPPORT = TRUE,要实现按耳机hook键控制FM调频功能

[SOLUTION]

实现步骤：

1，在uem_msg_hdlr.c（ps\l4\uem\src）文件中先extern void mmi_fmrdo_main_goto_next_channel(void);

2，再定义static void hook_earphone_press(void)

{

mmi_fmrdo_main_goto_next_channel();

}

3，在uem_msg_hdlr.c文件中函数uemdrv_aux_id_hdlr里

void uemdrv_aux_id_hdlr(local_para_struct *local_para_ptr, peer_buff_struct *peer_buff_ptr)

{

/*----------------------------------------------------------------*/

/* Local Variables */

/*----------------------------------------------------------------*/

aux_id_struct *p_aux_id_struct = (aux_id_struct*) local_para_ptr;

/*----------------------------------------------------------------*/

/* Code Body */

/*----------------------------------------------------------------*/

switch (p_aux_id_struct->aux_id)

{

case AUX_ID_PLUGOUT:

{

uemdrv_gpio_detect_ind(EXT_DEV_NONE);

break;

}

case AUX_ID_EARPHONE:

{

uemdrv_gpio_detect_ind(EXT_DEV_EARPHONE);

break;

}

case AUX_ID_KEY_PRESS:

hook_earphone_press();

uemdrv_gpio_detect_ind(EXT_DEV_KEY_1);

break;
