 		 #126068 - I rest my case, m'lud
Responding to: ???'s previous message

I mean, suppose somebody actually did it, and it was really possible to write something like the following and just know that it would work:
Save This Code
#define VARIANT SILABS_C8051F120
#include "8051api.h"

void main() {
    InitializeUART0(BAUD_9600);
    StringToUART0("Hello, Attila");
}
Wouldn't that be a liberating change from the endless farting around with SFRs that we do now?

But doesn't that just illustrate the inherent problem?

The example shows just one configuration option - the baud rate.
What about:
  • Interrupts enabled or disabled?
  • buffer configuration for the StringToUART0 function?
  • Different baud clock modes/sources?
  • Using the UART in shift-register or multiprocessor modes?
  • Automatic address recognition, for multiprocessor mode?
  • Crossbar configuration (since you mention the C8051F120)
  • etc, etc, etc,...

    With so many options for something as "simple" as this, I think coping with them all would be more trouble than just writing the code from scratch!
