I was wondering if idea of “bandwidth monitor” for ISP, Serial etc could be implemented. It would be very nice to tell bus utilization based on selected speed? How much actual data is TX/RX And maybe some errors?
For example tracing serial line set to 115200 I would like to see graph that shows TX and RX bandwidth to see how close it is to 115200. Perhaps if I notice that it is only using 19200 I might lower connection speed to sufficient 19200 to minimize transmission errors. Same for CAN and others. Any one like this idea?
