Re: Vida CEM swapping

Another way to write a shuffle, which I think is better is: B:P 0:3 1:1 2:0 3:2 4:4 ( .bin to Pin, 0 to 3, 1 to 1, 2 to 0, 3 to 2, 4 to 4 ). The advantages are: 1. It is easier to read and work with. 2. If you want to the reverse shuffle to get Pin to .bin: A. Flip each set, P:B 3:0 1:1 0:2 2:3 4:4 ...

Re: Vida CEM swapping

I like your way of thinking. But, have you tried to test those transcievers even on breadboard? Because now you are putting all your power and time to make new design and the result could be negative in case if craxker will not work correctly for some reasons... Sharp is using TJA1051T/3 so we know...

Re: Vida CEM swapping

You have to remove alarm in cem config and after - disconnect siren. If you have cem flash, send it to me, i'll remove alarm from config ( in case if you do not know, how to do it ;) ) Oh, also, also... Maybe internet wisdom knows at least where to start looking at... I'm planning upgrading my tire...
