Reply To: New Koryuu test firmware 1.1-test1

Hi @əotta,

Are you referring to the Minipro TL866 (or some variation thereof), by any chance? I could not find anything relevant when searching for TL899. I have not tried using that particular line of programmers for flashing the Koryuu. If you can get a connection to the 6-pin ICSP header, then it should be theoretically possible. There are a few caveats, though: 1) The logic level must be 5V, and 2) the programmer should not attempt to provide power to the Koryuu (“target mode” off), lest something burns out.

During programming, the Koryuu needs to be switched on and be powered by its own PSU.

What software do you usually use to program your atmega328p boards with when using the programmer you mentioned?

As for the ordering of the component outputs, through a firmware update or other programmatic means, it is only possible to swap R/B or Pr/Pb to B/R or Pb/Pr, IIRC, due to the way the DACs are assigned internally within the encoder. It is unfortunate that there is most likely no further flexibility offered by the video encoder chip. I’ll try to find the time to recheck and confirm this, though.
