J19 UART port mapping.
-
Hello Team,
@Chad-Sweet @modaltb
We are trying to connect a Ydlidar Tmini pro which has 3.3 V signal level UART interface. We are trying to connect it to J19 UART port in the voxl2 and would like to know which UART pins (GNSS or RC) to use for our requirement. Moreover, what will be the port mapping. For ex: whether it will be ttyHS0-3 or some other port.Thanks

Anubhav@Anubhav The J19 ports are only mapped to the SLPI DSP. You cannot access them directly from the applications processors. Are you running PX4 on VOXL2? If not then you can use libqrb5165_io (https://gitlab.com/voxl-public/voxl-sdk/core-libs/libqrb5165-io) to access the SLPI DSP UARTs from the applications processors.
