Hello!
Max6675 is extremely simple to use because (as far as I remember), there is no configuration
at all, you just select it, read and deselect.
But without your code, it's difficult to help you.
- Are you sure the SPI works as you widh (if you issue a read action, do you have a signal on the clock?)
- Does your LCD work?
Etc...
Dora.
PS: By the way, could you set a more meaningful title? "help code microcontroller" is basically the purpose
of the whole forum. Help reading max6675 would be more focused.
