Because of the limited flash space of Atmega16, the code of OSD is slightly changed, and it is not compatible with Michael's original config tool. So I adapt the config tool as well.
The Remzibi's OSD uses Megaload bootloader, so please use the Megaload programmer to upload the firmware. (The config tool can also upload the firmware, but I have to admit that it is not quite good right now.)
Thank binzi for providing the hardware.
