Hi Andrej,

You can try to increase startup power:
Code: Select all
#define PCT_PWR_STARTUP 20
#define PCT_PWR_MAX_STARTUP 25

Hi,

Just a quick update on the progress:
  • new dynamically adjusted ZC filter
    • less chances of misfire
    • one filter for all modes: startup/slow/fast
  • reviewed lost ZC recovery strategy. Now it recovers pretty much in all cases.
  • Support of Complimentary PWM for n-FET boards

Hi all!

@ziss_dm
While with the ZCFastSlow branch the ESC was still resetting, the v0.12 always recovers. Well done =)!

@Andrej
I used Mystery20A and pwm_fast_200 with the TY-P1. Which revision/tag are you using?

Cheers,
Heiko.

Just tested my ESC with the attached version and it works very well (the BEMF caps are not removed).

Did you set the fuses to ext. crystal / high frequency?
Can you confirm that your ESC is 100% identical to the one shown on the pictures?
Do you have another motor to test with?

Cheers,
Heiko.

Does a given firmware work for all models in a familly of ESCs?

Can I flash the Hobbyking SS 40-50A?

Hello,
- I did not set any special stuff (apart from what ziss_dm suggested).
- It looks pretty similar (apart from missing cap. from your picture), pleas check my picture.
- I've tested with 3 motors (heavy 910rpm/V, lighter apr. 2000rpm/V and small Hacker 4100rpm/V) all have sam issues.
- I've tested with your hex and issues are still here.

Hi crashlander,

Forget my question about BEMF caps, somhow I have missed that you are talking not about Mystery ESC.
But another question still remains: Is it starting motor(s) without props?

@Heiko
So, this board has all n-FETs but they are not inverted?
Why it is neccesary to change fuses?
Maybe it is better to pre-charge bootstrap capacitors for this board?

yes, this ESC has all nFETs (IRF IRLR7843) and works with the Mystery20A hw target. Somehow it uses 6 dual transistors (SMD code H11: CHUMH11PT) plus 6 other transistors (SMD Code Y1: ROHM EMY1 / UMY1N / FMY1A), but I don't have a schematic.

It's not neccesary to "change" the fuses, I just thougt maybe he didn't set them proper after the avr reset. We can try to pre-charge the capacitors, but this board works really well for me on all my motors. I have no startup problems at all, I can't imagine what's causing Andrej's problems.

Cheers,
Heiko.

@Heiko
I have not intentionally change fuses (I'm so fresh in AVR programing) so I'm using ziss_dm's manual how to upload using Arduino as ISP programer and modified _make.cmd form SVN (I'm Mac user that's why modified).

try to reset the AVR and set the fuses:

Code: Select all
avrdude.exe -C avrdude.conf -v -p m8 -P comX -c avrisp -b 19200 -e
avrdude.exe -C avrdude.conf -v -p m8 -P comX -c avrisp -b 19200 -U lfuse:w:0x3f:m -U hfuse:w:0xcf:m

After that, reflash the software. If that doesn't work, please post the avrdude output.

Cheers,
Heiko.

Hi Andrej!

I just tried Heiko's fuse settings (my original was different only in brown-out voltage). Since the symptoms are still present I'm posting avrdude output.

Hm, the log looks OK to me. Did you reset the AVR with the "-e" switch? Please connect one ESC directly to a reciever and try to start the motor this way. You can also record a short video that we can see/hear the problem ;).

Cheers,

I have problem with AVRootloader. I flashed ESC with software form first post on this site viewtopic.php?f=13&t=516&start=160 and set fusebits to High-Fuse: 0xCC and Low-Fuse: 0x2E
Now i can connect with flash software, write and read EEPROM, erese FLASH. But if i want to write flash there is problem.

logs:

Maybe some one have the same problem and can help me.

I guess AVRRootloader is compiled without Flash verify:

Code: Select all
.equ   UseVerify         = 0         ; Verify FLASH command (FLASH write/erase have implicit verify, can be deactivated)

Because the write command has implicit verify, you can uncheck "Verify device after programming" in the GUI.

I tried flash ESC with all kind of setings (in option section) but problem still remain.
The AVRootloader which I use, is from your link and it seems that UseVerify is set (.equ UseVerify= 1 )

if you use the one from my zip it should be enabled.

I checked your fuses, it seems that you set BOOTSZ to 256 words. I don't know if this will fix it, but please try:

Code: Select all
-U lfuse:w:0x3f:m -U hfuse:w:0xca:m

And this is what I get with "Verify device after programming" enabled and disabled in the GUI:

Only one question. Mystery 12A ESc like the others Mystery has two source of 5v on PCB. One is for atmega and second is for external device (receiver etc.) We can't power microprocesor for 3pin connector.
Is it safe to flash (AVRootloader) ESC with connected battery?

I always use the battery connection when flashing via BL. If you try a new and untested firmware, it's better to use a regulated power supply (9V/1A) instead of a LiPo :D.

Hi ziss_dm,

go for it! I'm very happy with your software.

There is one thing left, maybe we (or you ;)) can write a README which describes all the settings that can be configured with the hw/input files. Something like:

ziss_dm wrote:Almost.. ;) rpm = (motor rpm * rotor poles) / 2.

ENOUGH_GOODIES - number of successful electrical rotations before checking RPM.
RPM_START_MIN_RPM - minimal RPM for transition to run
RPM_STEP_INITIAL, RPM_STEP_MAX - initially when there no back EMF, it starts commutation with RPM_STEP_INITIAL speed and accelerates up to RPM_STEP_MAX. For a good start you need to provide enough power to rotate motor (with load) at least at RPM_STEP_INITIAL and motor should be able to produce detectable back EMF somewhere inside this range.

RPM_RUN_MIN_RPM - below this RPM it exits from run mode. Currently we have 2 cases:
- if current power is lower than PCT_PWR_MAX_STARTUP it goes to startup
- if higher - reset

Code: Select all
PWR_CURVE_POINT(01, 3500, 25)
PWR_CURVE_POINT(02, 7000, 50)

Basically it says that below 3500 limit power to 25% and below 7000 limit power to 50%. It is done to prevent overcurrent in case you put WOT at low rpm. ;)

I think this can help a lof of people. You can also add a sentence in the README that this software works with every PWM capable flight controller, and not only with multiwii. What do you think?

Cheers,
Heiko.

Hi,
Good Idea!! I was thinking, to use G.P. wiki for this:
http://code.google.com/p/wii-esc/wiki/H ... figuration

This way everyone can contribute(I'm a bad writer.. ;))

Or if we want fancy one, we can use Google Sites:

You are not the only one with bad writing skills ;), but how can we edit this page?

I would suggest we use google code, it looks easier to use.

I strongly support the idea of making the firmware a Version 1.0. Would be even better if we could get a supplier (or aftermarket supplier) to provide ESCs with this firmware RTF. (now that I have come to taste the sweetness going back to stock for other copters is not desirable)

Zero problems after hours of flying I think its ready for V1.0.......
I just finish the second version of the pcb. Pictures follow tommorow.......

Ziss, Please sent a PM with your adress so I can send you 4 ESC's (if you want).

Hi Everyone,

great work of all members here. Thanks.

for a VTOL project with EDF I need 40A+ ESC. The Turbojet 60A seems to be a good candidate for this job.
Because we have for hoovering high currents I want to modify the ESC.
For this setup activ freerun mode is used, or PWM with the hi-Fets.
The Turbojet ESC is pefect conditioned for this job, IR2101S hi-lo Drivers(output in phase with input), powered by a MAX662A charge pump.

My questions are:
do you have a firmware for all N-Fet setup?
do you have experience with IR2101 setups with hi-side PWM

here some pictures of the ESC and his schematic:

best Regards, Dieter

Hi,

My questions are:
do you have a firmware for all N-Fet setup?
do you have experience with IR2101 setups with hi-side PWM


1) Theoretically should work (this is just "bl-17a" schematic). I can create hw file later. But you would have to test it yourself. ;)
2) There are support for high side PWM, but it would not work well with this BEMF sensing circuit (virtual neural point).
3) There are support for complimentary PWM (activ freerun), but it is not tested really well.
4) Currently fw has limit: 240 000 electrical RPM, with EDF you may hit this limit. (or may not. ;))
5) Currently timing advance is fixed to 15deg which is good for low KV outrunners, but not sure for your setup.

Ziss,

I have find 1 bug.... if I slowly decrease the input down to 900us (with servotester) The motor is making (little) sound (startup active?).
If I decrease fast everything is shut down correctly.

I use pwm_fast_100.inc

and will you chance in Qynx20A.inc :
Code: Select all

#define DbgLEDOff          sbi     PORTD,2
#define DbgLEDOn           cbi     PORTD,2

; FET Control *****************************************************************


LED_AAN and LED_UIT can removed....


Thanks....

Hi ziss_dm,

thanks for your helps.
I have edit a hw file for the Turbojet60A.
Please have a look on it. I'm not quite shure about port inits and AnRef.
For the first step I want to use normal setup conditions.

"Turbojet60A.inc" see here: http://www.modfly.de/media/TorboJet60A_nFET.zip

Where can I find infos for a complete tournaround to save/reflash firmware.
I have some expierence with AVR Studio and STK500v2 compatible ISP prommers, not with AVRdude.

Firmware to use? ZCFastSlow or v0.12

Regards, Dieter

Hi Dieter,

Please have a look on it. I'm not quite shure about port inits and AnRef.

there is somehting wrong wiht your port initialization.

Code: Select all
#define INIT_PD         0
#define DIR_PD          (1<<c_comp)+(1<<rcp_in)
#define BRAKE_PD        (1<<CnFET)+(1<<BnFET))+(1<<AnFET)

All FET ports must be configured as output pins, c_comp an rcp_in as input pins:

Code: Select all
#define INIT_PD         0
#define DIR_PD          (1<<AnFET)+(1<<BpFET))+(1<<BnFET)+(1<<BpFET)+(1<<CnFET))+(1<<CpFET)
#define BRAKE_PD        (1<<AnFET)++(1<<BnFET)+(1<<CnFET))

Where can I find infos for a complete tournaround to save/reflash firmware.
I have some expierence with AVR Studio and STK500v2 compatible ISP prommers, not with AVRdude.

Ziss_dm explained here how to backup/flash a firmware. But you don't have to use avrdude, just use what you know best.

Code: Select all
Firmware to use? ZCFastSlow or v0.12

Try v0.12, or checkout svn trunk.

Cheers,
Heiko.

Should be fixed. ;) An I also cleaned-up Qynx20A.inc.

Hi Dieter,
I have commited bord definition for TurboJet60A. You can carefully test it. ;)
Please note that I have re-arranged phases to have them like here: http://home.versanet.de/~b-konze/blc_18 ... ematic.pdf

Hi Ziss_dm,
I'm having issues with TurnigyPlush6A (old ones, with Atmega proc) I traced the lines, and it seems that it has the same pinout as the Plush12A. However, if I flash the same firmware into a 12A and into a 6A, the 12A is working but the 6A does not start a motor. It newer reaches to a stabil rotation. It just shaking. I tried to play with the values without any success. Does anyone had a success with Turnigy Plush 6A ?

Hi EOSBandi,

Are you testing them with exactly the same setup? Same voltage/motor/prop?

EDIT: I have found schematic of Plush 6A: http://wii-esc.googlecode.com/svn/doc/Schematics/6a.pdf
Could you please confirm that this matches your board, especially comparator connections. If yes, we would need to create special configuration for them as it slightly different from normal Plushes.

EDIT2: In case your board looks exactly like here: http://home.versanet.de/~b-konze/blc_6a/blc_6a.htm. I have commited HW profile for it. Please be carefull when testing it. ;)

You are the man!
It's working now, i tested it at the bench, flight test will follow soon. Thank you for your dedicated work.

what was the differenc?

Hi,

Just B and C phases swapped and different comparator connections.

I would like to know if the Hobbyking SS Series 25-30A ESC
SKU (HK-SS30A @ $5.99) works well with MultiWii ?

it uses a Atmega8 or a C8051F330 ?

This ESC has need to be reprogrammed to work better ?
Is there a firmware for it ?

Thanks a lot for your answers !

as far as I know, they have a SiLabs C8051. If you would like to have faster throttle response (what results in better flight stability), it's necessary to reprogram every "China" ESC.

In my opinion, the best ESCs for reprogramming are currently the Mystery/HobbyKing BlueSeries types.

Cheers,
Heiko.

I own a 12A version with a F330.

I use the Silabs-IDE (3.61), Config2 (2.50) and sdcc-2.9.0-setup. I had some problems with the newest versions in the web and continued with the older one, I used before.

The actual files are here:
http://home.versanet.de/~b-konze/blc_f3 ... 120_hp.zip

You must open a new project, because my IDE has somewhere pathes saved or something like that. But it's very easy to build a new project.

Copy "input_ppm.c" or(!) "input_pwm.c" to input.c and the build the HEX, depending what input mode you want to use. The PWM input is designed for 4kHz 0%-100% PWM.

This is only a "play version", but is already running on my desk.

Don't use it in this state for real flights. I think, there are some improvements and tests needed previously.

Hi Bernhard,

nice work!

I have 4 Hobbywing Pentium 12A ESCs, but the MCU is the F334 with only 2kB flash. I guess thats not enough for your code?

Cheers,
Heiko.

This actual version has 0x08f8 = 2297 bytes, means it would not fit in a F334 version. But it should be possible to reduce code size.

This is a initial version for testing, for learning the behaviour of the silabs chip.
Additionally the port setting must be adapted to each ESC, as it is with the atmega software.

Would be appreciated, if someone could help testing.

Well, I will take HobbyKing BlueSeries type with your wonderful Atmega firmware ! :)

Are there any generic version already compiled (hex) in http://code.google.com/p/wii-esc ?
like https://github.com/sim-/tgy/downloads

Hi Synthex,

Currently there are no compilled .hex files. And not sure would it be possible ;(
Now we have 8 input methods and around 7 targets which is 57 hex files.

But we have nice instruction how to compile (tnx to Heiko!): ;)
