get a fixed string format for USB version string parsing
fix left border ver display for v1.2-3-g.., 1.2-34-g.. and 1.2-3456-g..
changes to make dfu (build *.dfu) and make flash (switch to dfu mode)
Signed-off-by: Martin <Ho-Ro@users.noreply.github.com>
Decrease sweep thread stack size from 640 to 512 (also stack usage code optimization give good result)
Little change 16x22 font
ui.c
Use definition for some hard coded values
Fix button "Correction" not reset after use "reset"
Define menu button and input num size
#define MENU_BUTTON_WIDTH 60
#define MENU_BUTTON_HEIGHT 30
#define NUM_INPUT_HEIGHT 30
Reduce button height from 32 to 30 pixels (fix in stimulus menu "<back" button overwrite by input num field)
Little code change
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
Decrease interrupt stack size
Use __ROR instruction in flash.c for checksum rotate
Fix erase background for frequencies string in plot.c
Implement getStringIndex function for parse string arguments, now Usage show correct information about used arg, and more easy use strings definitions
Example:
Need check if string "on" in avaible arguments list "load|open|short|thru|isoln|done|on|off|reset|data|in"
getStringIndex("on", "load|open|short|thru|isoln|done|on|off|reset|data|in") return 6
If not found return -1
Not need use if (strcmp() == ...) else ....
This usage save some amount of size
