標題: 串口助手實現流水燈和數碼管
有人能幫我改一下程序嗎,真不會

要求如下：利用串口助手，通過串口助手發送0，則流水燈左移，同時數碼管顯示管顯示0。發送1，則流水燈右移，同時數碼管顯示管顯示1。發送2，則流水燈中間向兩端發散，同時數碼管顯示管顯示2。發送3，則流水燈全滅，同時數碼管顯示管顯示3。發送4，則流水燈全亮，同時數碼管顯示管顯示4。

LedBuff[7] = 這一行都少了一個"{" 串口中斷服務程序要把按收到的數據進行分類選擇相應流水燈的控制，同時設置顯示緩沖區的數據，顯示程序由定時計數器負責顯示緩沖區的內容即可

那個{是我復制時不小心刪掉的,我是不知道怎么把上面那段程序改為要求那種的

電路圖呢？沒有電路圖改不了
