I had the FC-16 module working with LedControl.h library.
I had to install the LD-1088AS 8x8 matrix upside down such that the side with the label is on top.
I have eight of the modules chained.
I decided to try the MD_Parola library.
I changed MD_MAX722xx.h file #define USE_FC16_HW 1
It looks to be working, but I am not quite sure.
So, the last letter is displayed on the module closest to the Arduino?
