中斷讀取

十幾測試讀不到正確的電平，不清楚是不是編譯器或者語法問題

是需要定義一個函數(shù)數(shù)組嗎？

改一改uint8_t?(*key_read_func[CLICK_KEY_NUM])(void)?=?{key1_read,key2_read,key3_read,key4_read,key5_read};

發(fā)現(xiàn)原因了，按原先的定義數(shù)組，要加個括號才能調(diào)用函數(shù)，開始編譯器沒報錯以為那么寫也是對的呢

key_level = (uint8_t)((*(obj + i)).key_read());? ? 現(xiàn)在是這種寫法，順便再問一句，有沒有CH573的看門狗的例程@TECH_JW
