* bloonchipper: Add transport and sensor detectionTom Hughes2020-01-081-0/+28
bloonchipper (aka hatch_fp aka dragonclaw) has a voltage divider that can be used to select the sensor and the transport type. Supported designs: * Dragonclaw rev 0.2 (green with Google logo): go/dragonclaw-schematic-rev-0.2 * Hatch reference v3.0: go/hatch-schematic-rev-3.0 The selection lines are connected to ADC inputs, so a future change will use the ADC to allow more than two transports or sensors.
