APM 2.0 Dataflash Chip

Started this discussion. Last reply by Cadbury Dec 16, 2013. 1 Reply

I have a bent and battered 2.0, that went through some crashes. First, the Mediatek GPS got ripped off and I went with an external U-Blox. Then, to my astonishment, I found the SD-Card-like dataflash…Continue

Greetings.I have a quad equipped with RcTimer 5010 360KV motors and 16 inch props, running on 4S LiPo. Nice and steady platform for FPV and amateur video, flew it all spring and summer with a chinese…Continue

Para replied to nickthecook's discussion Questions for videographers
"Coaxial setups and GoPro footage don't get along too well. Because of the bottom propeller arcs, you are forced to mount your gimbal close to the aircraft center, and it will be hard to keep both the aforementioned props and the landing gear…"

Para commented on CSGShop's blog post NEO-M8N with GPS Glonass antenna + Compass ready for purchase and testing
"The M8N is fun. I get 11 sats and 1.0 HDOP in my livingroom, and that's below a metal roof and a reinforced concrete floor. But then I removed the NEO module and antenna and replaced a NEO-6 on a GPS that has external SAW and LNA. What do you…"

"I'm sure I saw this somewhere, but I can't find it now, so I'll ask: How do I enable IMU logging without a console ? :)"

"Attopilot 180A and a SBEC. I'd rather go with tested and trusted hardware for $30 extra, then risk a whole bird."

"It's hard to believe that vibration pulled off two DF13 connectors and the rest of the flying machine is still in one piece :)"

Para replied to Ben G.'s discussion Can't get my pixhawk quad to fly...
"Ben, starting with any DJI autopilot is not a good ideea. It's an extremely beginner-friendly system, that will actually teach one to gude the flying machine, not to fly it. The GPS and Simple/Supersimple modes (equivalent to…"

Para commented on CSGShop's blog post UBLOX NEO-M8N GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS receiver EVAL module ready for purchase
"I'm doing some comparative tests between a pair of "vanilla" GPSes, one Crius CN-06v2 and other Reyax RY825Al, sporting a NEO-6 and a NEO-M8N respectively, with just a 25x25x4mm ceramic antenna each, and no external LNA/SAW. I saw…"

Para replied to Pierre Gibouin's discussion 3DRobotics temporarily stops shipments outside of US and Canada
"Forgot the name, but it's that board Nick Arsov is building in Bulgaria. I personally don't like it because it has too few DF-13s. (-: Frankly, before Gary came up with the sparkfun link, I was thinking of someone hacking into 3DR servers…"

Para replied to Cory Hill's discussion Pixhawk + Taranis / X8R Fail Safe Configuration
"On X8R it's the SBUS. The horizontal connector below all the vertical PWM ones. Do not connect it to the S-Port where the antennas exit the case, because that's for telemetry."

Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"It's a rather convoluted setup, but it works. You have to flash the bootloader (either simonk's for use with Turnigy USBLinker or an AVRLoader to use with an Arduino) with an USBASP or equivalent, then switch to the single-wire programmer…"

Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"George, xoltri. I've played with my F-30s over the weekend. Simonk, BLHeli and Wii-Esc firmware. The winner is definitely Wii-Esc with comp_pwm on. Simonk 3/6/2014 won't desync anymore, but for 0.75 Kg of thrust it will ask for 8.8…"

Para replied to Bryan Anderson's discussion Pixhawk Quadcopter Yaw
"I don't know if an autotune will help a yaw drift, as it only tunes roll an pitch, but you might try it, because when a motor accererates or decelerates, the angular (yaw) influence is immediate, while thrust (roll/pitch) is a bit delayed. You…"

Para replied to Stone1295's discussion Pixhawk + Taranis X9D + FrSky X8R
"Stone. Get the Taranis in D16 mode and bind with the X8R in either Mode 4 or Mode 5 (instructions in the X8R leaflet or pdf). Get to the mixing table and start defining CH1-4 as AETR and add a switch or mix of two swithes to CH5, a pot on CH6 and a…"

Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"Then don't buy an ESC32 :) They have two calibration sequences that you do with the prop on, ramping up the motor between different rpm ranges. And if your parameters are unsuited to the motor, and it detects a desync, it screeches to a sudden…"

Para replied to Ritche M's discussion help needed: motors will spin only at 40% throttle and hover at 55%
"If you're using the Quadro ESCs, I'd advise you to buy a SiLabs ToolStick and reprogram them with BLHeli. The GUI allows you to set min/max pwm values and min_command on each ESC."

Para replied to Nolan Crook's discussion Generic Magnetometer on APM 2.6??
"Nolan, you can't differentiate between two HMCs. Just make sure SCL goes to SCL and SDA to SDA. I2C is not like a serial port where Rx goes to Tx. Then pay attention to mag orientation. Default APM orientation is chip facing up and pin1 dot on…"
