NEW FIRMWARE WITH OLD HARDWARE?

Post by wtfwtfdef »

I have an old tvbgone 1.1 edition from way back. I want to upgrade to the latest firmware that comes with 1.2, because there seems to be alot more codes for North america. Is this possible, can I direct flash the tvbgone.hex to the attiny? Or should i just work at porting the newer firmware and codes into the old firmware code? Also does anyone have any knowledge on flashing the attiny85? I am reading posts from way back when and i understand that I might need to desolder the LED's and resistors to program the chip on the tvbgone board. Is it ok to leave everything else just remove the LED+LED'S RESISTORS?

Any help or ideas would be appreciated.

The V1.2 firmware should work with V1.1 hardware.
I'm not sure about removing the resistors to re-program. I'll have to check on that.

you do have to remove the single driver resistor but you can cut one side and then resolder it. unfortunately, the hardware has changed and v1.2 firmware is not compatible with v1.1 i believe - the transistor arrangement changed!
