Minim OSD v1.1

Minim OSD v1.1
Minim OSD v1.1

This is a mini Arduino based on-screen display board. It's tailored for use with ArduPilot Mega and the MAVlink protocol, and designed to be as small as possible.
 
It's main components are an ATmega328P 8 bit microcontroller with an Arduino bootloader, and a MAX7456 monochrome on-screen display. Programming is done through an FTDI-compatible 6-pin cable.

It features two independent power and ground sections to isolate the OSD's analog stage: a +5V section for the ATmega and the OSD's digital stage, powered through the FTDI cable or other +5V source; and a regulated +5V section for the OSD's analog stage, powered through the video in/out header and capable of handling up to +12V input.


Features:


• ATmega328P with Arduino bootloader
• MAX7456 monochrome on-screen display
• FTDI cable compatible pinout
• Standard 6-pin ISP header
• Two independent power sections with an LED indicator on each
• Solder jumpers for combining the power sections
• +5V 500mA regulator for up to +12V supply input (5-12v range)
• Solder jumper for PAL video option
• Exposed test points for HSYNC and LOS

Specs:
Voltage: 5-12v
Dimensions: 50 x 18 x 10mm
Weight 4g

Great product! Using it with my DJI Naza lite and could see every gps data.

Since upgrading to the second last Arduplane, the OSD parameters do not show up on the monitor every time the system is powered up. I have to push the reset button on the OSD board to get it going. My Apm is version 2.5. Have tried to refresh the OSD firmware using different version, without success. Can anyone suggest reason for that ? Thanks Frankie

Maybe the Arduino bootloader got corrupted somehow..or the MAVlink code..i can*t really tell from those details what is going wrong

Hi Nightfall, Thanks for yr reply. I tried uploading a previous firmware, such as arduplane 2.78, but without success. I also tried to install the APM board again by following the Wizard, that doesn't help either. What may have done wrong with the MAVLINK code ?
 NightFaLL 42 points
Then the problem might lay in the ArduPlane config. I guess you have to modify some params to allow ArduPlane to communicate via serial 3 with MinimOsd. I will get back with a link.

I also went to the same link which you gave me, and I forwarded this link to my buddy which is also into UAV and FPV. He also cannot find the SR3 parameters in the Full Parameter List in the Mission Planner. Do you know where they are ? I can see the SR1 parameters but not the SR3.. My arduplane is the latest version.
 NightFaLL 42 points
What board are you using? SR3 only works if you have a board with an atmega 2560 microcontroller like APM 2.5/2.6
 Frankie 2 points
MIne is APM 2.5. I once saw these parameters when I started using MinimOSD Extra instead of the usual Arducam OSD Configuration Tool. But when I have this problem, I could not find these SR3 parameters. Strange..
 NightFaLL 42 points
Strange indeed. Try upgrading osd's firmware to somethin 1.9 . If that fails too try reinstalling arduplane (last version) and try to add the osd via mision planner hardware configs..hope it helps
 Frankie 2 points
I did all these.............upgrading or downgrading OSD recent firmware (total 3-4), also re-installing arduplane V3.0.1 (the latest), also pressed the "enable telemetry" button in the Mission Planner Initial Setup **- Optional Hardware page, all these did not help. My buddy just told me the SR3 parameters were replaced by the SR1 in the Full Parameters List. So I changed my setting according to the values in the OSD trouble shooting section. That did not help either. This problem creates another problem **- after I re-installed the latest arduplane, the " distance to current waypoint > current waypoint No." became very large (1>65535) , instead of the usual 0>0. These 2 figures appear under the flight mode on the HUD in the Mission Planner. I did not set any waypoint during trouble shooting the OSD problem. Do you have any clue ?
 NightFaLL 42 points
This is really odd but i have to admit it is getting way out of my knowledge area. Sorry mate. I hope you will be able to solve your problem.

I recently built a new quad with APM and using MinimOSD with 'MinimOSD-Extra' firmware. Here's my last flight at night.

hi . Please help. How to make minim osd read rssi i solder resistor onboard. wire signal wire from open lrs. now how i can change code to minim osd understand to start read it?
 NightFaLL 42 points
I think you need to get the RSSI signal to the flight controller to get it into the mavlink transmission.
 facedown 8 points
Thats is one options what I will try next. Connect apm2.5. But I know there is another way. Anyway iw I have one w tx and 100mw rx is the rss will send back 100mw and if rss will be low 1w stil send enought power to recive control. It mean no point from rssi if I have signal rss from tx.
 NightFaLL 42 points
You are right with that. I think APM will solve your problem. Please click Best Answer if this answer helped you or anyother answer.
 facedown 8 points
Nightfall I will give you best unsver avarde. But you dont telme nothink what I dont know and wrealy 0.01 $ is that w hat you want? I more interest of some answer of clear instructions how to get rssi to apm. Clear mesuring resistors and capacitors. And how to wire them

Works at 5V/PAL (soldered the jumpers) without any problems. Very nice product! Paired with HK MegaPirate AIOP board v2.0 plus HK UBLOX plus HK Bluetooth. Nice combo, Hobbyking!

excellent product, got it working with multiwii easier enough after flshing rush-osd and setting it up via rush gui. would be nice if you had jumpeers for your external monitor leads rather than having to solder onto the main chips legs but that it a problem with the initial design not hobbykings copy of that. i run mine off 5v with the soldered pads.

Just burned one because I connect it to one battery.
Note: make sure you are using a flight battery and a vtx battery.
