README

        
This C-library contains code for interaction with STC15W408AS. STC15W408AS is a micro chip compatible with 8051 architecture.

# Versions history

0.1.0 

* first version

* system sfr headers support

* bits manipulations

* uart support

0.2.0

* headers flat structure

* doxygen documentation

* add get chip id function (value F51FC47E1D0B52 for STC15W408AS)

* add master clock and divider frequency functions

* adapt delay_ms to clock divider, uart not adapted yet

0.3.0

* add master clock output to pin P5.4 or P1.6 with dividers 1, 2, 4

* get mode functions for timer0 and timer2

* get clock divider functions for timer0 and timer2

* timer0 mode0/12T and mode0/1T implementation with sync and interrupt (async) support. No GATE and INT0 support for timer0 running, only TR0 used for start and stop timer . No P3.5 output.  

* timer2 mode0/12T and mode0/1T implementation with interrupt (async) support. No P3.0 output.

0.4.0

* Enable and disable timer0 mode0 output to P3.5 pin supported now

* Enable and disable timer2 mode0 output to P3.0 pin supported now

* timer0_enable_on_pinINT0_high implemented for timer0 work only on INT0/P3.0 pin is high

* timer0 and timer2 use interrupts module routines

* Interrupts module implemented (with interrupts priority and int0/int1 trigger config support)

0.4.1

* frequency module use defines instead of function decl for output hex code decreasing 

* interrupts module use defines instead of function decl for firmware size decreasing

* timer module use defines on commons functionality instead of function decl for firmware size decreasing

0.5.0

* delay module now use defines instead of func decls

* timer modules now use defines instead of func decl 

* timer0_modeX_run_once_and_wait now have only one parameter uint_16 - timer ticks count

* timer0_start and timer2_mode0_start now have only one parameter uint_16 - timer ticks count

* timer0 and timer2 are modules now

* timer0 and timer2 mode0 reload timer routines implemented

* timer0 mode1 implemented

* timer2 mode0 implemented

0.6

* timer0 mode 0,1,2,3 module full implementation

* timer2 mode0 module full implementation

* Aux module convert ticks to frequency implemented 

* Aux module unsafe convert frequency to ticks

* timer_all.h to timer_common.h renamed

* delay_ms partially rewrited to asm to decrease size 

* UART to UART1 renamed

* Fix: UART bias timer0 1T by setting AUXR.7 value to 1.

* timer2 baud rate ticks calculation implemented

Next releases todo

* TODO Calculate frequency ranges for 12T/1T timer dividers and MCU clock scales

* TODO Make safe version of timer0_frequency_to_ticks_unsafe

* TODO Make safe version of timer2_frequency_to_ticks_unsafe

* TODO Implement ticks to times part of aux module

* TODO Add example links to module documentation 

* TODO Implements counters
