Hi,
I am having some difficulties interfacing the 8051 to the MAX7221 driver chip using SPI. As I understand it, it receives a 16bit signal and that would require bit-banging as the 8051 only sends 8bits. I am having trouble understanding how to do this in the assembly language.
The uC is 8051f340 from SiLabs.
Thanks
