Status LEDs
Bus Probes feature two status LEDs — greed and red. LED patterns of Bus Probes conform to Tibbo's standard LED patterns used on our programmable devices.
Here is the list of LED patterns supported by BP sensors:
- During the device boot, after the Monitor/Loader (M/L) verifies the integrity of the application firmware:
