Version history

0.1.0

• first version

0.2.0

• headers flat structure
• doxygen documentation
• add get chip id function (value F51FC47E1D0B52 for STC15W408AS)
• add master clock and divider frequency functions

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
• UART1 use timer2_mode0 and timer2 aux modules routines now
• Implement ticks to times part of aux module for timer0, timer2

0.7

• Fix: remove variables from delay module
• Reset routine implemented
• Watchdog timer routines implemented
• delay_ms now is define again
• Idle power managment routine implemented
• Power down mode implemented with initial wakeup timer support
• Use bitmask as a constant in bits.h to avoid unnessary bit operations in bit_set and bit_clr
• Use bitmask as a constant in bits.h to avoid unnessary bit operations in test_if_bit_set and test_if_bit_cleared

0.8

• Add memory dump example
• WakeUp timer implemented
• Times to ticks part of aux module implemented
• Docs are included to platformio package
• Examples compilation is a step of build
• Enhanced description of project for indexing in google/yandex and so on search engines
• Pin module implemented

0.9

• Pin module set port mode routines implemented
• Fix examples/mode0/timer2 compilation
• Fix timer0_mode2_reload - TH0 value should be set, now used TL0
• Fix INT0 should be defined in timer0 modes
• timerX_modeX_direct_{reload, start}(TxH, TxL) for direct set TLx, THx registers implemented
• Does not recompile examples every time. Compile only when it changed
• Compiler output suppressed for examples building in non verbose mode

Next releases todo
