/*
  * Show messages on an 8x8 led matrix,
  * scrolling from right to left.
  *
  * Uses FrequencyTimer2 library to
  * constantly run an interrupt routine
  * at a specified frequency. This
  * refreshes the display without the
  * main loop having to do anything.

سلام میشه یه راهنمایی بهتر بکنید مخصوصا قسمت بستن مدار رو نمیدونم چیکار کنم .عکس اصلا مربوط به این نیست کد هم مربوط به 8x8 است نه این لطفا کمک کنید

[magmagmary]

این برای مدل 8*8* هست که اگه بخواید برای 16*16 استفاده کنید باید کد رو تعمیم بدید

میتونید از این لینک برای 16*16 استفاده کنید:

سلام.

هر چه سرچ کردم چیزی که دقیقا پین ها و بوردش مثل این (محصول موجود در سایت آفتاب) باشه ندیدم!
