Programming cl-osd onto board.

Updated May 16, 2012 by call...@gmail.com

Programmer

You need a AVR programmer in order to program the chip on the board. There are several

different types of programmers and in this case I will focus on USBASP since that's what I use

and it's cheap.

Soldering

There are six pads on the boards that you need to either solder cables to or add a socket to.

The pitch of the pads are 2.0 mm which means that we need a special socket that has 2.0 mm

pitch. If you don't have those at hand you can use a normal 2.45 mm pitch socket as Parity has

done here:

Then you can use some sort of jumper cable sutch as these:

Connecting board and programmer

Now it's time to connect the board with the programmer. Connect each of the cables together

with jumper cables according to the following images:

E-OSD programming pins (by kristaps_r) G-OSD programming pins AVR ISP programming header Note that this pinout is for the header and not the cable. Just to make everything a bit more complicated. I could not find a pinout image for the cable. VTG should be connected to +5 Volt.

Get avrdude I use avrdude to program my boards but there are alot of other options. For example some programmers such as the STK500 are able to program using the AVR Studio. But in this example we use avrdude, get it here. Note: If you have an atmega88PA instead of an atmega88 read this page. Programming NOTE: Do not change the fuses on the AVR unless you really need to! You might brick you chip.

Hi, I try this with my 0 experience in programming, just wanna update my G-OSD. No luck with avrdude, is says flashed OK but no change on the OSD. Did it with eXtreme Burner and works fine at the first try, just had to ignore the non recognition of the Atmega88 chip and write anywhere. Thanks Comment by berkelyb...@gmail.com, Jun 21, 2012 For the cable layout, that would be the following 2 pictures.
