นี่คือประสบการณ์ของฉันของ SeeedStudio E-Ink
http://www.picaxeforum.co.uk/showthread.php?23583-E-ink-on-PICAXE-see-it-now- !
E-ink Seeedstudio เป็นเกราะที่เข้ากันได้กับ Arduino (อย่างไรก็ตามมันไม่เข้ากันได้กับ Arduino อย่างเต็มรูปแบบ! ดู Seeedstudio Forum: http://www.seeedstudio.com/forum/viewtopic.php?p=16432#p16432 )
นี่คือรหัส PICAXE:

มีชิปที่ใช้งานอยู่เพียงสองตัวเท่านั้นใน Shield, ROM อักขระและไดรเวอร์ E-ink
รหัสจะอ่าน ROM เพื่อรับรูปแบบบิตจัดเรียงบิตใหม่จากนั้นส่งไปยังไดรเวอร์ E-ink
ฉันไม่พบชื่อของผู้ผลิตใด ๆ บนหน้าจอ E-Ink เองเว้นแต่ว่าผู้ผลิตจะเรียกว่า 'Good Display'! (คำเหล่านี้เป็นเพียงคำเดียวที่ด้านหลังและหมายเลขชิ้นส่วน GDE021A1) (แก้ไข: ฉันเพิ่ง Googled หมายเลขชิ้นส่วนอีกครั้งและในครั้งนี้พบผู้ผลิตมันเป็นจอแสดงผลที่ดี!)
ความคิดของฉันคือว่านี่เหมาะสำหรับแอปพลิเคชันที่เหมาะสมฉันแค่ต้องการค้นหาแอปพลิเคชันนั้น
