LibDriver AS608

AS608是一個指紋掃描儀和讀取器模塊，但它的功能遠不止於指紋注册、圖像處理、列印匹配等等。它處理數據並發送處理後的數據通過串列傳輸到微控制器。該設備使用DSP晶片進行圖像處理渲染、特徵查找、計算和蒐索。它有一個內寘的閃存，可以存儲指紋的數據，並注册新的–最多可以存儲162個指紋。它與控制器或具有TTL串列的任何其他系統，並發送數據包來拍照，檢測列印、雜湊和蒐索。該設備具有紅色和綠色LED指示燈，用於錯誤和正確的印刷品。

LibDriver AS608是LibDriver推出的AS608全功能驅動，該驅動提供指紋錄入、指紋驗證等功能並且它符合MISRA標準。
