Creating RTX51 Tiny Applications

Writing RTX51 Tiny programs requires that you include the
found in the
using the _task_ function attribute.
RTX51 Tiny programs do not require a main C function. The linking process will in-
clude code that will cause execution to begin with task 0.

RTX51 Tiny Configuration

You can modify the RTX51 Tiny configuration file
subdirectory. You can change the following parameters in this configuration
\C51\LIB\
file.
n
Register bank used for the system timer tick interrupt
n
Interval for the system timer
n
Round-robin time-out value
n
Internal data memory size
n
Free stack size after RTX51 Tiny is started

This code allows configuration of the
'RTX51 tiny' Real Time Operating System
; define the register bank used for the timer interrupt.
EQU 1 ; default is Registerbank 1
; define Hardware-Timer Overflow in 8051 machine cycles.
EQU 10000 ; default is 10000 cycles
; define Round-Robin Timeout in Hardware-Timer Ticks.
EQU 5 ; default is 5 ticks.
;
; note: Round-Robin can be disabled by using value 0.
