Right - well it's expected that you'd have to run SAMConfig in
onInit- after all, the NFC doesn't remember anything.However you shouldn't need
I2C.setup- thanks for yourdump()command output - it looks to me like this is a bug in Espruino (the digitalWrite would end up resetting the pins after they'd been set up for I2C).
