DiSlord	d2431f0cdc	Increase screen render (in some cases up to 2x speedup), decrease stack usage (code size less on 1500 bytes) ... Write simple profiling definitions START_PROFILE STOP_PROFILE Use it for detect sys tick amount and output to screen main.c Reduce VNA_SHELL_MAX_LENGTH to 48, and made shell_line as static (reduce stack usage) Remove BaseSequentialStream *chp from command calls (use static shell_stream), it reduce code size and stack usage Use VNA_SHELL_FUNCTION definition for all commands Remove chMtxLock(&mutex);chMtxUnlock(&mutex); from commands, and define command flag for use it in calls Apply default scale from trace_info on trace change Led blink outside from main sweep cycle (better look, and less noise) Some size fixes chprintf.c Implement small memory stream object, only put function and plot_printf(char *str, int size, const char *fmt, ...) Use it in all code (little increase speed, and huge decrease size) Restore USE_EXCEPTIONS_STACKSIZE = 0x180 (possible not need, but not good tested) plot.c Made huge screen render profile (add some comments) Not use cell clipping on draw cell data (use constants increase speed, decrease stack usage (not need put it to stack)) Clip cell if need only on screen flush Use new plot_printf, remove chsnprintf usage Apply code style ============================================================================================================ Interesting fact Usage memset(spi_buffer, DEFAULT_BG_COLOR, (h*CELLWIDTH)*sizeof(uint16_t)); dramatically decrease render speed possibly it fill buffer by 8 bit data, so slow Usage uint32_t *p = (uint32_t *)spi_buffer; while (count--) { p[0] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16); p[1] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16); p[2] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16); p[3] = DEFAULT_BG_COLOR|(DEFAULT_BG_COLOR<<16); p+=4; } gives x10 speed perfomance Draw polar and smit grid very slow (but i don`t know how increase it except use bitmaps, but it need about 5-8k flash size and file prepare) On long lines render slow down, but clipping use more calculation, and not give good result Need made stack usage check	6 years ago
DiSlord	02a5715bb4	Big code redisign (increase CELL draw size, more faster screen render), also save about 4-5kB flash size ... Try remove all hardcoded values from code (use definition if set) Some error fix main.c: Rewrite Shell, now it run on main thread and require less RAM (not need stack) (possible run it as thread if define VNA_SHELL_THREAD Remove not used trace_info[].scale_unit in set_trace_scale/get_trace_scale (it just divede on set and multiple on get, better use it for default scale set) Replace some hardcoded values MARKERS_MAX SAVEAREA_MAX TRACES_MAX plot.c Rewrite CELLWIDTH and CELLHEIGHT use, now possible set any CELL width and height (CELLWIDTH * CELLHEIGHT <= spi_buffer size) Free RAM from shell stack use fore increase spi_buffer size now it have 2048 pixel (64x32) Rewrite cell index and markmap use (now correct use cell size, and more faster), correct use CELLWIDTH and CELLHEIGHT in calculation Fore set update area use invalidateRect (still need use some hardcoded values :( ) Rewrite cell_draw_line Rewrite many hardcoded size definitions Refrence point now draw as bitmap (less size, more costumable) Fix drag marker (now correct search closest index in search_nearest_index) Rewrite plot_into_index, now correct use size definitions, moe ui.c Small rewrite keyboard definitions, for use less flash size Define KP_WIDTH, KP_HEIGHT for set key size Better look some big font symvols All: use static fore some local functions (use less space on calls) replace tabs on spaces (code style) Use M_PI from math.h fore define pi value Fix printf on print HEX values	6 years ago
DiSlord	e9f65b1426	Huge rework chsnprintf function (basic functional more compact and faster): ... I can`t upload my version chprintf.c to ChibiOS\os\hal\lib\streams upload it to root :( now support print float and Suffix if use example %.1F on 1.234e-3 print 1.234m, %F print 1.23m now support + flag %+d on 8 print +8, %+d on -8 print -8 now support freq output if use %q example %q on 1234567890 print 1.234 567 890 GHz, %.8q print 1.234567GHz fix rounding errors on print float example if print use %.2f on 2.199 print 2.20 (before 2.19) Use it in code - made more compact (save about 2k bytes) and easy display values (set output more digits after . for some values) Made some font glyph more compact, allow 3px glyph More correct create frequencies table on big span (not use float operations), also produce more compact code Use double value input from keyboard (not lost Hz on input) Set sweep_points as uint Optimize set_sweep_frequency size Fix freq commands broken after freq set as uint32 (add str to uint32 functions for freq bigger then 2 147 483 647): cmd_freq cmd_offset cmd_threshold cmd_scan cmd_sweep Define _isdigit macro (replace isdigit() function, its too big) Rewrite std universal atoi() to more compact my_atoi and write new unsigned variant my_atoui	6 years ago
