I am attempting to use the Serial 7-Segment Display with a CMOD-A7 FPGA board to simply display a 16 bit value as hex on the display. I have the values showing correctly on the display, but the order of the numbers changes every time.
For example, I am testing trying to get it to show “1234” on the display, but when programing the board it will show “2341”, “3412”, “4123”, or sometimes “1234”.
Attached here is my code.
