Re: ISO INTERFACE FOR USB

Nah ... to transform an RS232 device to USB only a chip is needed ...
a lot of converter around ... they works transparently, so no code
change needed ....

I tested few of them ... and i found (as said) problems getting right
timing ...

Cheers,

Ida

Now microchip, cygnal, and many other companies make cheap processors
that have USB ports. The challenge is in implementing the OBD
protocol on these processors. If only ELM would port their code to
one of them. :0)
