Need for speedup calibrate if need
 2020-03-24 11:04:34 +03:00
DiSlord 48e28f79d0 Use compact variant sin_cos table in fft (not decrease speed, and need only 208 bytes flash) 2020-03-23 15:10:01 +03:00
DiSlord 9221ad04ca Revert, use sin_cos table in fft.h 
#define FFT_USE_SIN_COS_TABLE by default
Increase code size on 700 bytes, but huge speedup (x3) transform

Merge pull request #126 from DiSlord/master 
Fix screen artifacts, change start/stop or center/span mode set, remove Mutex use
 2020-03-21 09:22:06 +09:00
DiSlord 597c2c2958 Better solutiom of prev fixes (reload si5351 settings on sweep begin) 2020-03-15 16:02:22 +03:00
DiSlord 23c765b719 Fix very strange bug, on band 2 
!!!!! Don`t understand why si5351 non stable on band 2 then change from band 3
It fixed if set before sweep one frequency from band 1 (for example 50MHz)
Possibly problem in tlv320aic3204_set_gain, call only si5351_set_frequency_with_offset not work

Little faster call command from shell

Fix interpolation if points < POINTS_COUNT
 2020-03-15 14:14:52 +03:00
DiSlord 3eb8a4cfe9 Fix interpolation range if sweep_points!=source calibration points count 
use sweep_points exept POINTS_COUNT on marker search and so

Now possible change sweep_points in process (for faster sweep)
 2020-03-14 21:23:02 +03:00
DiSlord fdb3886b0f Move define to str macro in nanovna.h (it allow output define valuer in error messages) 2020-03-14 16:50:35 +03:00
DiSlord 45dfd7d970 Fix sweep if points < maximum (mot sweep if frequency[i] == 0) 
Fix my tupo in extended scan command (not correctly parse point count)
 2020-03-14 16:48:36 +03:00
DiSlord 8a11eaa764 Extend scan command, now in have additional input variable (optional), allow more faster get measured data 
usage: scan {start(Hz)} {stop(Hz)} [points] [outmask]
[outmask] - optional, allow output measured data, its a mask (allow dec, hex, bin, oct)
0b001 - output frequency
0b010 - output CH0 data
0b100 - output CH1 data
Example:
'scan 1000000 5000000 101 0b111' - output data in format: freq ch0[0] ch0[1] ch1[0] ch1[1]
'scan 1000000 5000000 101 0b101' - output data in format: freq ch1[0] ch1[1]
'scan 1000000 5000000 101 0x7'   - output data as 0b111
 2020-03-14 16:05:26 +03:00
DiSlord ec81a01226 Not use float in vbat measure (faster, less size), yes get little error (but less then 1mV) 2020-03-14 15:21:26 +03:00
DiSlord 922b66abdb Move offset variable to si5351.c (better use it as independent library) 
Define and move constants in nanovna.h, and use it
Fix command 'marker' - display marker freq (not current freq)
 2020-03-14 15:18:14 +03:00
DiSlord 88617a31fe In ili9341.c remove tabs, add palette mode blit function 
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
 2020-03-13 22:42:28 +03:00
DiSlord 8bdb650212 Implement color command, allow change color settings in config (enabled bu default ENABLE_COLOR_COMMAND) 
Usage: usage: color {id} {rgb24}
- Grid color: id = -3
- Menu bg color: id = -2
- Selected menu: id = -1
- Trace 1-4: id = 0..3
Color in hex RGB format (but possible any type input, dec, hex, bin. oct)
 2020-03-12 21:43:35 +03:00
DiSlord 6f25d0d43f Remove Mutex use (CH_CFG_USE_MUTEXES = FALSE), now all Mutex depend functions run in sweep thread 
It allow:
- reduce shell thread stack size
- more compact code
- fix some hardcoded scan command code, allow write better scan version
- run calibrate (not depend from pause sweep flag)

Rewrite uint32_t my_atoui(const char *p), now its allow read:
hex 0xaAbBcC1122
dec 12345678
bin 0b00011100
oct 0o12345678

Add some comments
 2020-03-12 19:53:58 +03:00
DiSlord 51b5cce016 Fix Random jitters at band 1 and band change on some freq ranges 
Improve frequency stability on band change (100 MHz, 150MHz, 300 MHz, 450MHz)

Restore freq cache in CW mode
 2020-03-11 20:11:46 +03:00
DiSlord 10ae59e786 Little cleanup 2020-03-09 23:57:03 +03:00
DiSlord 3714e05395 Fix artifacts after marker move 
(For faster screen update on marker move, all old area update info invalidate after use draw_all_cells(TRUE) on page switch)
Force redraw all cells after end marker move
 2020-03-09 22:47:35 +03:00
DiSlord eebb625b9d Always update marker info 2020-03-09 22:28:05 +03:00
DiSlord 04fb661b1a Add flag in config for sweep mode 
#define FREQ_MODE_START_STOP    0x0
#define FREQ_MODE_CENTER_SPAN   0x1
Now sweep mode not defined from frequency0 > frequency1 or frequency0 < frequency1
frequency0 always < frequency1

All freq must get by use get_sweep_frequency(mode)

Revert Select CH0 reflect channel before set freq, add additional delay on 0 sweep point
 2020-03-09 18:24:31 +03:00
DiSlord f9074149bb Size fixes, use define exept const, typdef index_t for indexes 2020-03-09 16:18:29 +03:00
DiSlord 19121b3371 Auto determine mark_map mask size from MAX_MARKMAP_X on compilation (up to MAX_MARKMAP_X = 32) 2020-03-09 14:40:17 +03:00
DiSlord 2d273a5548 Fix typo 2020-03-09 14:22:59 +03:00
DiSlord a19722cdc3 Reduce last patch fix size (use pointers) 2020-03-09 14:08:06 +03:00
DiSlord 90407d5730 Fix screen artifacts: 
In mark_cells_from_index(void) mark all rectangle (in most cases this not decrease render speed, and more fast in calculation, and no errors)
 2020-03-09 13:12:01 +03:00
DiSlord 5cf86ee1a6 Revert dsp changes, need more research 2020-03-09 10:28:33 +03:00
DiSlord a2d90a5e91 Try not lost data on dsp (Less noise on small signals) 
Use int64_t acc for values
Use double on calculation

Not cache freq on si5351_set_frequency_with_offset (to fast change in rare cases on cw mode, and process wrong DSP block) as i write before need change DSP delay tactic
