**************************** * * * Flysky GT3B-PSX manual * * * **************************** This is a preliminary manual for alternative firmware for FlySky FS-GT3B radio and clones. This manual is written as differences to original firmware. This firmware is completely written from scratch and is not compatible with the original Flysky firmware. It is distributed with NO-WARRANTY. All of the model setups saved by original firmware will be erased!!! You can backup your original firmware and config, use tabs "PROGRAM MEMORY" and "DATA MEMORY" in STVP to read it from radio a save it to disk. Global characteristics: ======================= - 15 models memory (for 6-channel firmware, for 3-channel it is little more and for 8-channel little less) > numbers 10-19 will show with Right-Arrow > numbers 20-29 will show with Left-Arrow - added Subtrims - added SaveAs to save model config to another memory location - added Global Setup menu to change function features, including backlight time, battery low voltage, etc. - dead zone for steering and throttle - added key mapping specific for each model memory - calibrate menu will be automatically invoked after first power-on with this firmware, so 6 menu items will start to blink Buttons: ======== - it is now possible to differentiate between long press (>1 second) to normal button press (short) and it will be recognized like "ENTER-long" - Trims and DualRate > now shows changed value only temporaly (5 seconds or till another key press), values are saved to EEPROm automatically when it disappears > when autorepeat disabled on trims (default), reset trim to 0 by pressing both trim keys together for long (eg. TRIM_LEFT-long + TRIM_RIGHT-long and similar for channel 2 trim) > while value is showed, it is possible to change it with rotate encoder also > when value set to reset_value (usualy 0), longer beep sounds to attention to it and short pause is intruduced to ignore keys Standard menu: ============== - swapped behaviour of ENTER and END when editing items, ENTER now select next value and END (+ ENTER-long) will end editing items - ENTER-long on ABS will leave menu also (as BACK) - Trims are now only for steering and throttle - Expo > value for channel 2 is splitted to forward and back and is indicated by arrows > positive values are those You want to use like at Spektrum radios - DualRate > value for channel 2 is splitted to forward and back and is indicated by arrows - SaveAs > choose menu MODEL and press ENTER-long > menu MODEL will blink > choose memory position where to save model config > press ENTER/BACK to save it - Model reset > choose menu NAME and press ENTER-long - Subtrims > choose menu TRIM and press ENTER-long > menu TRIM will blink > set subtrims for each channel > press ENTER/BACK to end this submenu - Steering speed > choose menu D/R and press ENTER-long > menu D/R wil blink > now only channel 1 can be selected > turn wheel left to show left arrow - this represents Turn speed 1-100% > turn wheel right to show right arrow - this represents Return speed 1-100% 100% means no delay 1% means above 4s delay end to end - mixes 4WS, DIG, throttle brake cut-off (for boats with forward-only throttle), Multi-Position (to set arbitrary up to 8 positions) > choose menu EPOINT and press ENTER-long > menu EPOINT will blink > select one of mixes 4WS (4), DIG (d) or brake cut-off (b) for mixes 4WS, DIG: > press ENTER and choose channel for this mix or OFF - for dual-ESC steering (boat, tank, ...) select DIG channel 1 and with D/R reduce required ESC travel (at 100% it will go to contra to allow steering at place) > press ENTER and set mix in range -100...0...100 % 0% is default and means both channel have same max steering/throttle 100% means 100% reduce on rear steering/throttle (eg. no steering) -100% means 100% reduce on front steering/throttle (eg. no steering) > for 4WS press ENTER and select crab (CRB) or no-crab (NOC) for Multi-Position: > press ENTER and choose channel for this mix or OFF > press ENTER and set channel value for first position > press ENTER and set channel value for second position or END > ... up to eight position for brake cut-off: > ser OFF or CUT - Key mapping specific for each model: > choose menu REV and press ENTER-long > menu REV will blink > choose trims (id 1 2 3 d) or other keys (CH3-C, Back-b, End-E) or if trim is OFF, then also trim keys (id 1 2 3 d with left/right arrow) > press ENTER and modify first setting > press ENTER and modify next setting > .... ----- steps of settings of trims (1 2 3 and D/R): - sequence: function -> buttons -> step -> reverse -> opposite_reset -> previous_val -> rotate id: % % V V V blinking % blinking % V blinking - function: selected function listed at the end of manual - buttons: MOM - momentary, hold left/right trim key to get end values, when nothing pressed, servo is at centre NOL - no long keys, long press is the same as short press RPT - autorepeat is on RES - long press of one of trim keys will reset to centre/reset value END - long press of trim key will set to coresponding end value - step: select trim step for one trim key press (1, 2, ... 100, 200), not available when buttons MOM or fuction is list of items (MPO) - reverse: NOR - no change REV - swap left/right trim keys - opposite_reset: not available when buttons MOM NOO - no change ORS - when trim key is pressed and value is at opposite side of centre/reset, set value to centre/reset, - previous_val: available only when buttons MOM or fuction is list of items (MPO) NPV - no change PRV - instead of setting value to centre/reset when key is released, it is set to previous value, which was active before key press - rotate: available only if fuction is list of items (MPO) NOR - no rotate ROT - rotate from max item to 1.item and back ----- steps of setting of keys (C b E 1< 1> 2< 2> 3< 3> d< d>): - sequence: function -> momentary -> reverse -> prev_val -> function_long -> reverse_long -> prev_val_long id: % V % blink % V V % blink - function: selected function listed at the end of manual - momentary: only available for 2-state functions (channel, ...) SWI - key press will switch something (channel value, ...) MOM - value change will be active only while key is pressed - reverse: only available for 2-state functions NOR - no-press or default value is left endpoint REV - no-press or default value is right endpoint - prev_val: only available for 2-state functions NPV - key release or OFF state sets value to left endpoint (noREV) PRV - key release or OFF state sets value to value active before key press or ON state - function_long: function applied when long press of key happens, choose from the same list as function - reverse_long: same as "reverse" - prev_val_long: same as "prev_val" Calibrate menu: =============== - enter it by wheel right-turn and ENTER-long - 6 menu items starts to blink - use END or ROTATE to change channels - there is also channel 3 representing CH3 button (for those who will do some 3-position switch/potentiometer modification) - there is also channal 4 representing battery voltage - calibrate as usual (for channel 1/2 left+mid+right and ENTER) > calibrated value will disappear from menu > it is not needed to calibrate all values - calibrate battery (it will not be probably needed to use this) > select channel 4 > press ENTER > set your current battery voltage (measure it by voltmeter) > press ENTER to save it or END to no-save - press BACK-long or ENTER-long to end calibrate menu and save values Key-test menu: ============== - enter it by wheel left-turn and ENTER-long - if ENTER-long keep pressed, all segments on display will stay on till ENTER is released - now check keys by pressing them short or long - if keys long pressed, an "L" symbol will appear left to displayed key symbols - press BACK-long or ENTER-long to end key-test menu Global setup menu: ================== - enter it by ENTER-long - now menu items MODEL and NAME will start blinking - select requested item by ROTATE and press ENTER - use ROTATE to change value and press ENTER to end value changing - press BACK-long or ENTER-long to end global setup menu, values will be saved to EEPROM - selected menu items are indicated by following symbols: F firmware version (this of course cannot be changed :-) L backlight time 5s,10s...10m...MAX A inactivity alarm OFF,1m...10m LOW POWER! battery low voltage 7.5...10.5V E.POINT maximum allowed endpoint value 100...150% DANGER - values greater than 120% can damage your servo or will not be possible to transmit to receiver because of 2.4GHz HF module limitation This danger zone will be indicated with a flashing "d" symbol for values greater than 120% 1 dead zone for steering 0...50 2 dead zone for throttle 0...50 b key beep OFF/ON d long press key delay 100...1000 miliseconds r + ALL global reset - change to YES to set global configuration and all models to default values r + MOD all models reset - change to YES to set all models to default values Return to original (and modified) firmware: =========================================== - flash original firmware - delete whole EEPROM (tab DATA MEMORY in STVP and write those empty zeroes) or return back your saved config (also tab DATA MEMORY in STVP, read your saved config from disk and write it to radio) - calibrate steering and throttle (not needed when You returned back saved config) Functions assignable to trims: ============================== OFF - nothing, it is possible to assign each button individualy as key TR1, TR2 - trim of channel 1/2 DRS, DRF, DRB - dualrate of steering/forward/back EXS, EXF, EXB - expo of steering/forward/back CHn - change channel "n" value in range -100...100 STn - subtrim of channel "n" 4WS - 4 wheel steering mix -100...100% DIG - DIG throttle mix -100...100% MPO - Multi-POsition, switches position up/down SST - steering speed turn 1...100% SSR - steering speed return 1...100% Functions assignable to keys: ============================= OFF - nothing CHn - switch channel "n" value from one end value to opposite end value. There is special handling for CH3 button. When using 3-position switch instead of CH3 button and momentary is selected for this button, then centre 3-pos value will also be detected and set to servo (but this was not tested yet, I wouldn't do this modification to my radio). CnR - reset value of channel "n" to centre 4WS - switch crab (CRB) no-crab (NOC) for 4 wheel steering DIG - switch DIG mix between -100 and 100 (more useable when using return to previous val key setting) MPO - Multi-POsition, switches position up (at END back to 1.) MPR - Multi-Position Reset, switches position to first one
