Teensy 4.1 One-Cycle FSK

I’m building a proof-of-concept transmitter that must output a single, precisely timed cycle of FSK per data bit on a Teensy 4.1. The bit stream is stored exactly as volatile uint8_t dataBits[] = {1,0,1,1,0,0,1};… (Budget: €30 – €250 EUR, Jobs: Analog Electronics, Arduino, C Programming, Circuit Design, Digital Signal Processing, Electronics, Embedded Systems, Microcontroller)
