Excel seems to keep crashing on me. Is it bc of my sample rate? CPU usage goes up to 60% while the app is running but doesn't seem to be draining resources completely. It collects data for about 400 rows and then crashes. I tried baud rate 9600 and 115200. It seems to be more stable if I increase the delay to 100ms (sampling rate of 10Hz) But realistically I need to sample at least 50Hz.
