I am currently thinking about using the HT1632C to control a LED matrix, but I have some questions about it.
I understand how to work with a single HT1632C, but I am having some trouble understanding its cascade mode. How does the cascade operation works? How do we send a message containing the information about a certain LED to the third slave, for example? How does the master know the information is for the third slave, and not for the second? Is there any kind of address associated with each HT1632C unit, so that we know where to send the information?
I would also like to know how many HT1632C can we cascade on a given application?
