Great!

Ben has measured the timings again on his wonderous scope, and sent me the attached capture (below) of an I2C transmission.

Based on that, I've now added an extra microsecond to high pulses of SDA, giving it more rise time. But I've also fixed the low pulses to be *much* quicker, as they hardly need any time at all to transition.

Hijack v506 is now released with the I2C rework completed.

Cheers
