MultiWii

Ok, I figured it out. Now the problem is that, to configure it in the GUI, I'll need to build the GUI to talk to the OSD at 19200. I've got the source, and I've installed Eclipse and JRE, but I'm not sure how to open and build a java project. Can anyone point me in the direction of how to build MW_...

Our cloners are lazy. Smart ones don't clone cheap stuff in the first place anyway

Suggestion: Blink # of sats while waiting for GPS fix

I didn't test this, but should work.

If the board is tilted more than a certain amount (30 degrees?) green will start blinking and it won't arm. If it's not tilted but you changed board orientation (with align_board_*) try recalibrating the accelerometer.

I have the font file from an OSD product. If somebody is interested to get 'inspiration' from their font and make better font/characters for this one, here's a preview.

Question, When Im on the github baseflight firmware main page and I click on the "Downlaod Zip" button in the bottom right of the page am I getting the very latest baseflight.hex? Or do I have to get it another way for the absolute latest updates to baseflight.hex If so I can not figure o...

iirc, (TC correct me if I'm wrong) for altitude GPS is never used, so if you haven't covered the baro unit on the Naze with dark foam it is not surprising to have such effects.

But it didn't in my case. It could only use it as a ubx gps when i did set gps_baudrate=4 (9600 baud), but i didn't realize that it should have worked then I try It again with Naze32 rev0 and rev4, but with "Chrome Google Baseflight configurator" and I had the same issues, GPS is not dete...

Ok this is working for me. But what are the optimal settings for baseflight? - 115200 baud - protocol in and protocol out only ubx - which messages are needed? i like to kick out everything else or at what baudrate do i have to configure it so autoconfigure will work in baseflight? gps_baudrate is ...

Just flashed latest baseflight from configurator, GPS seems to work for me. It's an ublox NEO-6M.

4. CLI access You can use for example: CoolTerm. You can download it from here: m 5. MultiWiiConf 2.2 (if needed) for serial you can use screen use it like so: "screen /dev/tty.SLAB_USBtoUART 115200 -xion" to quit you could use ctrl+a and then k, or just unplug usb and it will disconnect....

Here I've published my changes. Also includes a better (well, at least "kinda working") pwm rssi handler for FrSky receivers.

Today I even attempted using hardware timers and pin change interrupts to measure the PWM signal, but failed to get stable results. Code here.

A few things. Which FrSky receiver are you using? The new X8R does not use PWM RSSI. Just analog voltage. So it's easy to plug straight in. Also, it works fine with the MISO pin. The trick.... You have to have it plugged in and working when you make the change in the GUI or it will hang. It's worki...

Problems with PWM RSSI and current r370 code: In the config, default PWM RSSI pin should not be the MISO pin (12) since it's already in use by the MAX chip and nearly hangs the OSD (pulseIn blocks too much) when enabled. Make D3 (pin #3, PAL jumper) default instead. (Config.h, line 8) KV_Team_OSD.in...

Switch rx/tx lines and try again.

Here is another useful patch, backported from baseflight (jef78m is the original author, m ) Allows dumping of matching cmdline variables by running an incomplete set command. ie. something like "set gps" will dump all gps variables. (I tried with stristr/strcasestr, but couldn't make it i...

Short notice, a first test Version for v5 is in the github repo. You should add a zero-byte to MSP_STATUS reply to indicate current profile id even if Harakiri doesn't yet support profiles. Just to avoid breaking MSP. ("global_conf.currentSet" in msp documentation) Here's a quick diff: --...

Any plans to make it compatible with FrSky telemetry data? ie. connect a single wire from a flight controller (MultiWii with frsky patch, Baseflight, etc) to both the RX and OSD and get the data on both using a single serial connection on the FC side. Of course that would mean removing all the MSP c...

Here is my branch, based on QuadBow's FrSky Telemetry code. m Update 2: Also added a Multiwii 2.2 based branch, at m disq, I finally got a chance to try your code tonight with not so favorable results. I have a witespy Mega Ez 3 (ATMega2560) with baro, mag, GPS. While I did receive telemetry data b...

Just took this process loop implementation on baseflight/stm32 for a test flight, very nice! Great work alex.k!!! The values posted here by Phil.S are great, though I added a little more RC Expo.. I'll maiden it on one of my Crius AIO Pros on the weekend... Also in baseflight i_level is limited to ...

I'm assuming you mean the dohicky to connect the Multiwii to the Frsky RX ? I've been using this : multiwii_to_frsky.png That one works better than the PNP version that's been floating around on the interwebs so use it Btw still, if you're short of serial ports but have a few kb of extra space, you...

(Yeah that trace goes into the MAX chip as well) Good news, PAL jumper FTW then Can't solder a pin there, but at least soldering a wire will be easy.

PWM is "solved because I will code it to use digital PD3 instead of MISI,(something Itai and me figured while chatting other day) or you can easily do it also if you like, just the input please, the code is OK. The only bug is with the ADC value on screen when using the OSD analogue input (it ...

Hi, Looks like this was missed during code refactoring, in the I2C code GPS-Hold P value is sent twice instead of P&I. File: m #if defined(I2C_GPS) i2c_rep_start(I2C_GPS_ADDRESS<<1); i2c_write(I2C_GPS_HOLD_P); i2c_write(conf.pid[PIDPOS].P8); i2c_write(conf.pid[PIDPOS].P8); /* this should be .I8 ...

I added a modified i2c-gps-nav fork to my github. It has DISTANCE_TO_HOME_IN_METERS as an option in config.h. (You still need to modify MultiWii for this to work) I couldn't resist and also added FrSky telemetry, so if you don't have space for a FC in your fuselage you can still have the GPS-coordin...

For the max 655-meter distance-to-home stuff, instead of waiting for a fix/release you could easily follow these steps to convert the distance to home unit in transmission to meters. 1. Comment out (or remove) this line in MultiWii GPS.ino GPS_distanceToHome = GPS_distanceToHome / 100; //register is...

Here is my branch, based on QuadBow's FrSky Telemetry code. m I converted the code to be compatible with the latest Multiwii (r1424, but vbat/motors/rpm not tested) and also added Softserial support, using SendOnlySoftwareSerial. This way you don't need to dedicate a serial port for the telemetry, i...
