Now need use blit8BitWidthBitmap for draw image
Now big bitmap image need define as uint8_t bitmap array, for more easy use _BMP16, _BMP24, _BMP32 macro
Redefine bitmaps arrays vs this macro
Now bitmap image can be any width and height
Now any bitmap image can be draw transparent on cell
Result code more compact
>Multiline text - now possible output multiline in one print (for 2 line buttons for example)
>But syntax is "1_line_text\n2_line_text" possible 3 line and bigger (need only more bigger height for output)
In plot.c prepare for 8bit/pixel mode (test, allow increase cell buffer size by use 4 or 8bit/pixel mode, but not need for now)
main.c little change wait execute shell command in sweep thread
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
Rework display spi driver:
use DMA for read, write
add blitBitmap functions
Use DMA for color fill
More correct SPI bus control
Move color definitions to nanovna.h
Some code optimization for speed and size (save about 3k bytes)
Change grid Y resolution to 10
Fix convert from float to int (fix some rounding errors on plot)
Disable unused HAL serial
Change battery icon
