Integer promotion bug

I think there is a bug in the C51 and CX51 compilers regarding integer promotion. I have not deselected integer promotion and thus expect proper C semantics without adding casts. The bug seems to...

Integral Promotion

We are currently in the process of evaluating Keil tools for possible purchase. Using the evaluation package, I have been checking some common functions. One of them is a simple bit test macro suitable...

Timer, t1-t0, integral promotion

For ARM7, A hardware timer is 32-bits, and unsigned int is 32-bits too; For a 16-bits MCU, A hardware timer is 16-bits, and unsigned int is 16-bits too; So, t0 = timer_val; while ( ( timer_val...
