HT16K33を使用した、8x8 matrix led
4個でのスクロールを試してみた

text = "ぎおんしょうじゃのかねのこえ しょぎょうむじょうのひびきあり さらそうじゅのはなのいろ じょう しゃひっすいのことわりをあらわす おごれるひともひさしからず ただはるのよのゆめのごとし たけきもの もついにはほろびぬ ひとえにかぜのまえのちりにおなじ"

text_len = len(text)

while True:
    for i in range(0, max_images):
         for j, m in enumerate(matrixx, 0):
            m.image(image_listx[j][i])

※
i2c_address=(0x71, 0x70,)の部分を
i2c_address=(0x70,)　とかにすると
16x8 で動きますね
