don't kill the messenger, I know that this my video is not taken by multirotor, but just wanted to show how accurate can an old BMP085 sensor be, I still can't believe it. on my multirotors I have MS5611 and although it does work better than BMP, it's still no 'Naza like' alt. hold. watch the second...

dr.tom

I am happy how 180 servos linked above work

they are also very cheap.

sorry for late reply,

I fly with Hitec Aurora 9 + Rangelink 433MHz
for FPV flying with 1.5W readymade video TX + IBCrazy's cloverleaf+ crosshair antennas .

on gimbal equipped MWC multirotors gimbal servos make all sort of rapid movement during first 3-4 seconds of battery being plugged in, many times I had to unplug them to allow board to initialise properly before this mod, so this surely helps, because no unplugging is needed more, p.s. is there a wa...

thnx will try it, and report. this seems to be executed when doing stick input calibrations, m from multiwii2.1, multiwii tab, line 724 else if (rcData[THROTTLE] > MAXCHECK && !f.ARMED) { if (rcData[YAW] < MINCHECK && rcData[PITCH] < MINCHECK) { // throttle=max, yaw=left, pitch=min i...

dr.tom

Yes, I am aware that servos go to rx on the plane, I emphasysed that in my video, gimbal code would be usefull for HT too if it was giving out the PPMsum for injecting into rc link. (imho it gives better response, no lag and more precise, as seen in my vid, if it could be modded to give PPM out, it ...

dr.tom

Thank you very much for your will to help. here are the GUI scrnshts if needed for debug 1. with new version and HT_debug commented, servos react the same way, move like they should, but with some lag and random jitter like in video http://imageshack.us/a/img404/6389/debugnotactive.th.jpg 2. with ne...

dr.tom

i tried to remove acc readings, and force code to output same value (middle) no matter what acc input is. and it is working, no response on tilting the board, servos are staying in center, but still twitching. http://imageshack.us/a/img221/5042/origw.th.jpg http://imageshack.us/a/img21/9788/delvq.th...

dr.tom

here's the video, with both analog and digital servo for eliminating them as cause of twitches. m first test: MWC code for flying, with gimbal active, (could work for headtracker but doesn't have PPM out to inject it into stream...) second test: this HT code, just uncommented the type of board, ever...

dr.tom

Great stuff! I would like to try it on my fpv plane. but I tested it on my mwc boards, that fly well. and gimbal works well of them, so nothing broken. m CRIUS SE on the left, and GY86 on the right http://imageshack.us/a/img833/5387/boardsx.th.jpg sadly, I have random servo twitches, around +/- 5° i...

dr.tom

so, for now

the only way to fly that IMU(and GY86 I have, same mag orientation) is on good old 8bit atmel?
ordered this shield:

hope developers will come upon a solution,
performance is not everything, keep that in mind.

dr.tom

at least 1 mag axis is reversed on this 32bit board due to pcb layout http://www.goodluckbuy.com/kcopter-stm32f103cbt6-flight-control-board-with-itg3200-bma180-hmc5883l-ms5611.html copter is pointing north, but in gui arrow shows south (180 degrees shift). pitch axis is reversed, roll and Z is ok as...

dr.tom

you need to define GIMBAL in config section, not multirotor. (and adjust servo travel... define which board it is..) that way stabilisation will work even without receiver, only 5V is needed if you want, you can connect pitch and roll to turn camera manually where you want, and still have stabilisat...

dr.tom

it sure tries different speeds because my AIO+gps (rctimer) works with Bandi's code even withouth GPS battery!
(removed it to test the eeprom mod, but it didn't remember settings with it, so I just desoldered eeprom and then Bandi's code came right in time to test it)

dr.tom

Just pIcked up a nice ready made AT328 based I2C module, would it be difficult to modify the ATTiny code to run on it ? I have an HC-SRF04 kicking about, between them it could make for a very simple to build and low cost I2C sonar sensor, any thoughts http://www.rctimer.com/index.php?gOo=goods_deta...

try to clear EEPROM before flashing with latest mwii.

it's in arduino menu under 'tools' or 'sketch samples' I believe, look for it.

dr.tom

glad to hear that,
it would be great if you could test if battery would hold from weekend to another(6-7 days),
that's about as long as we put our models unpowered,

if it can only hold a day or two... it's too short. EOSBandi EEPROM hack is 'a must' then.
thanks

dr.tom

2 dr.tom, Thanks for the info, what MultiWii board are you using? According to RCTimer's picture of their i2c interface at their website, it is pluged into the CRIUS SE board's UART port. Can someone confirm if this is correct? Thanks for your time. I had navigatron i2c soldered to Crius SE board, ...

dr.tom

2 little nellie: yes, the one linked is serial GPS, but I don't have it yet, considering to order it if it turns out compatible... the gps module on rctimer page has some flaws that EOSBandi described in his guide some pages before. most of all it needs eeprom chip to be usefull (to not forget it's ...

dr.tom

I've flew my last model with flytron i2c gps, it worked great,
now it is out of stock for over a month and I need new sensor for some other model.

is this compatible? looks like it should work

dr.tom

Did you copy included files to your arduino library folder?

dr.tom

ok, stm32 it is

did you buy the SKU: 83736 one with newer MPU IMU that has some internal acc+gyro sensor fusion if I remember correct
http://www.goodluckbuy.com/kcopter-stm3 ... -chip.html

or SKU: 83734 with well tested ITG+BMA IMU
http://www.goodluckbuy.com/kcopter-stm3 ... s5611.html

all stm32 versions seem to have only 6 PWM outputs, so it can't be used on hexa + 2servo gimbal?
