Hi!
I want to use the MAX6921 chip bit banging SPI software. Totally confused when to H or L level of the CLK and LOAD terminals. I do not understand how the shift in 20 bits? If I use a VFD tube IV-18, should be subject to a, b, c, d. .. segments and grids? How can I specify that the first digit to be written in such an 8?
Please help me a sample code because I have a headache and not feel so good.

This thread will get you started:

But you must learn the C language, read the CCS manual, study the CCS
data types and learn how many bits can be held by each type, and study
the shift_left() function, and modify the code to do what you need.
