Hi,
I am using Serial1 at higher baud rates(921600 and 3000000), i want to know how reliable is Serial1.read() at lower core clock. Usually i set teensy3.5/3.6 core clock to 120Mhz but if i set core clock to 48Mhz for these baud rate, will there be error involved while reading or writing data?
I have added hardware flow control for Serial1, if that sufficient to avoid uart errors?
