申請到是AB32VG1的2.0的開發板！

因用到彩燈需短接J8,J10,J12，TF卡需短接P2的對應pin，

應用RT-Thread Studio IDE，可快速實現對組件包的配置！

軟件實現

led 彩燈的線程如下：

static void led_thread_entry(void* p)
{
uint32_t cnt = 0;
uint8_t pin = rt_pin_get("PE.1");
rt_pin_mode(pin, PIN_MODE_OUTPUT);
uint8_t pin1 = rt_pin_get("PE.4");
rt_pin_mode(pin1, PIN_MODE_OUTPUT);
uint8_t pin2 = rt_pin_get("PA.1");
rt_pin_mode(pin2, PIN_MODE_OUTPUT);

while (1)
{ rt_err_t result = rt_mutex_take(mutex1, 6);
if (result == RT_EOK) {
state = wavplayer_state_get();
rt_mutex_release(mutex1);
if (state== PLAYER_STATE_PLAYING) {
if (cnt % 8 == 0)
{
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_HIGH);
}
if (cnt % 8 == 1)
{
rt_pin_write(pin, PIN_HIGH);
rt_pin_write(pin1, PIN_LOW);
rt_pin_write(pin2, PIN_HIGH);
}
if (cnt % 8 == 2)
{
rt_pin_write(pin, PIN_HIGH);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_LOW);
}
if (cnt % 8 == 3)
{
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_LOW);
rt_pin_write(pin2, PIN_HIGH);
}
if (cnt % 8 == 4)
{
rt_pin_write(pin, PIN_HIGH);
rt_pin_write(pin1, PIN_LOW);
rt_pin_write(pin2, PIN_LOW);
}
if (cnt % 8 == 5)
{
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_LOW);
}
if (cnt % 8 == 6)
{
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_LOW);
rt_pin_write(pin2, PIN_LOW);
}
if (cnt % 8 == 7)
{
rt_pin_write(pin, PIN_HIGH);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_HIGH);
}
cnt++;
}else if (state== PLAYER_STATE_PAUSED) {
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_HIGH);
rt_thread_mdelay(400);
rt_pin_write(pin, PIN_LOW);
rt_pin_write(pin1, PIN_HIGH);
rt_pin_write(pin2, PIN_LOW);
rt_thread_mdelay(200);
}
else {
rt_pin_write(pin, PIN_LOW);
rt_thread_mdelay(500);
rt_pin_write(pin, PIN_HIGH);
rt_thread_mdelay(500);
}
rt_thread_mdelay(200);
}

}

}
音樂播放控制用到了兩個線程。一個通過按鈕事件線程控制音樂播放！一個通過音樂播放狀態來檢測是否切換歌曲，避免播放一首之后，因無按鈕操作而停止！

按鈕事件線程：

static void btn_thread_entry(void* p)
{
while (1)
{
rt_thread_delay(RT_TICK_PER_SECOND / 500);
rt_err_t result = rt_mutex_take(mutex1, 6);
if (result == RT_EOK) {
button_ticks();
rt_mutex_release(mutex1);
}
}
}

音樂播放狀態來檢測線程：

static void endCheck_thread_entry(void* p)
{
while (1)
{
rt_thread_mdelay(2500);
rt_err_t result = rt_mutex_take(mutex1, 2);
if (result == RT_EOK) {
state = wavplayer_state_get();
rt_mutex_release(mutex1);
if (state == PLAYER_STATE_STOPED) {
EndState = 0;
rt_thread_mdelay(1000);
result = rt_mutex_take(mutex1, 2);
if (result == RT_EOK) {
state = wavplayer_state_get();
if ((state == PLAYER_STATE_STOPED)&& (EndState == 0)) {
EndState = 1;
if (currentSong == NUM_OF_SONGS) {
currentSong = 0;
}
GetCurrentPath();
wavplayer_play(table);
currentSong++;
}
rt_mutex_release(mutex1);}
}

}
}
}
