यहाँ SeeedStudio ई-इंक का मेरा अनुभव है।

Seeedstudio ई-स्याही एक Arduino संगत ढाल है। (हालाँकि, यह पूरी तरह से अर्डुइनो संगत नहीं है! देखें सीडस्टडियो फोरम: http://www.seeedstudio.com/forum/viewtopic.php?p=16432#p16432 )
यहाँ PICAXE कोड है:

शील्ड पर वास्तव में केवल दो सक्रिय चिप्स हैं, एक चरित्र ROM और ई-इंक ड्राइवर।
कोड बिट पैटर्न प्राप्त करने के लिए ROM को पढ़ता है, बिट्स को फिर से व्यवस्थित करता है, फिर ई-इंक ड्राइवर को भेजता है।
मुझे ई-इंक डिस्प्ले पर किसी भी निर्माता का नाम नहीं मिला, जब तक कि निर्माता को 'अच्छा प्रदर्शन' नहीं कहा जाता। (ये पीठ पर केवल शब्द हैं, और एक भाग संख्या GDE021A1) (EDIT: मैंने सिर्फ भाग संख्या को फिर से प्राप्त किया है, और इस बार इसने निर्माता को पाया। यह अच्छा प्रदर्शन है!)
मेरे विचार हैं कि यह सही अनुप्रयोग के लिए एकदम सही है, मुझे बस उस एप्लिकेशन को खोजने की आवश्यकता है।
