Hi once again

I built the 'Arduino Nano as IR sender and receiver'. I tried the code 'protocol Panasonic, D=176 S=1 F=91' but nothing happened.

I tried the original Panasonic remote and captured the signals and what I discovered till now is that the protocol is Panasonic, D=160

Thanks,

Thanks for the help. I like your project and thinking of building 1 I downloaded the hex file firmware but I cannot download the Xloader program.

Which Arduino Nano version should I buy (3.3V 8MHz) or the (5V 16Mhz).

Thanks,

Panasonic SA-HT990 stuck in ST MODE

Panasonic SA-HT990 stuck in ST MODE


Hi all,

I have a Panasonic SA-HT990 which is stuck in ST MODE after trying to make it region free with an application.

I tried to do a factory reset but the player is not responding. I am thinking that I will have to install new firmware.

Anyone can help ...
