While playing with newly arrived Micro MinimOSD and attempting to flash it with latest MW OSD software, I’ve discovered that offical tutorial, as well as many other are missing one tiny detail that makes whole process much harder than expected. In theory, MinimOSD just Arduino Pro Mini with additional hardware. So, in theory, you plug in your FTDI USB adapter and upload a sketch. But if you never worked with Arduino Pro Mini (like me, it was always Uno, Pro Micro, or barebone Atmega328) you might not know one detail. Yesterday it took me more than 30 minutes to figure out firmware upload is not working, while it should. So, another tutorial will be written.
To flash MW OSD to Micro MinimOSD we will need:
- Micro MinimOSD with soldered pins, but isn’t this obvious?
- USB to Serial cable adapter like FTDI FT232RL with drivers installed,
- MW OSD software downloaded,
- Arduino software,
- 5 female-to-female golpin wires,
