Splash Screen and Display Characters #13

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Cleared EEPROM
2.Installed KV Team OSD software/firmware using arduino board setting aurduino 
duemilanova w/atmega328 and selected com port, my case 10
3.Run KV Team GUI 2.2, browse font, selected MW_OSD_Team.mcm uploaded. able to 
edit/view fonts.
4.Reset OSD controls, Selected settings for OSD, write to OSD and Saved 
settings.
5.Hooked MinimOSD KVT (cut trace and checked with multimeter) to MultiWii Pro 
ez3 board ser "0" port also tried ser 1 and ser 3 ports. Both blue leds on and 
green led flashing. Camera FH18C 520tvl wide voltage mini camera (NTSC) Working 
voltage: 3.6-24V and TS832 Transmitter/RC832 receiver which is plugged into 
4.3inch monitor set to nTSC 16:9.
6.Monitor displays splash screen and display but with funky looking characters? 
see attached pictures.
7.What is wrong with Characters displayed. Is it a bad MinimOSD KVT
What is the expected output? splash screen and display to look like the  video 
teaser you have on youtube.

What do you see instead? see attached

What version of the product are you using? On what operating system?
KV Team 2.2 and MultiWii Pro ez3/Quad firmware from witespy

Please provide any additional information below.
Currently MinimOSD kvt trace cut and checked, pads are soldered. Powering MW 
board will power minimOSD KVT but will not diplay any video. but when I use 
cam/tx battery to power video cam/tx, minimOSD KVT and MW board work and video 
is displayed? I don't like the idea of powering all four components via cam/tx 
battery. 
I've also desoldered pads on MinimOSD KVT and used separate power for MW 
Board/MinimOSD KVT and powered cam/tx and MinimOSD KVT side. Board lights up 
blue and green leds but no video output/display? 
Please Help!

The software version I see is not 2.2, is r370.

What is your exact OSD model?

If your jumpers are in truth closed and both blue LED´s on, is known that some 
FTDI´s don´t really have the output voltage that MAX need, this is why some 
users report that they try several times until a successful upload.
Another option you have in order to try to solve this, is to power your MAX 
externally with a battery (video side) and ground your FTDI/PC.

As for not powering up with your FC board it´s rare and seems to me that you 
have a faulty one. 
If both blue LED´s are on (assuming you have the OSD I think you have) you 
should have video also...
(Powering the video side externally solve it like you mentioned).

Hope this help you somehow and get you up in the air for real fun.
I will tag this issue invalid because it is not a software defect, you can use 
the forum (visible on main page) to continue this conversation if you need more 
help from us.
Cheers.
