Sample format

The probes (on the device housing) are numbered 1-8. They seem to have internal pull-ups, i.e. if you don't connect them to the target, their value will be high (1).

• 8 probes: Bit 7 is the value of probe 8, bit 0 is the value of probe 1.
• 4 probes: Bit 3 is the value of probe 4, bit 0 is the value of probe 1. Bits[7:4] are probes 4..1 respectively.
• 2 probes: Bit 1 is the value of probe 2, bit 0 is the value of probe 1. Bits[7:6], bits[5:4], and bits[3:2] are probes 2..1 respectively.
