Serial Hello
demo Open · freely redistributable
An original CC0 bare-metal i.MX RT1062 program. It gates LPUART6 and GPIO in CCM, configures pin 13 as an output, sets the LPUART6 baud divisor and enables the transmitter (CTRL.TE), then prints "Hello from the Teensy 4.0 (i.MX RT1062)!" repeatedly — waiting on STAT.TDRE / STAT.TC for each byte — while blinking pin 13. Exercises the real LPUART6 transmit path onto the serial console (TX on pin 1, Teensy Serial1).
