10 I2C Programming in Real-Time Operating Systems
I2C transmissions are slow, typically 100 kHz. In systems like Arduino, your code must wait for each transmission or reception to complete before doing other work, which drastically reduces your application’s performance. While waiting, the CPU is just executing a busy-waiting loop (also called a spin loop), wasting CPU cycles. In this chapter, you’ll learn to use real-time operating systems (RTOSs) to put those CPU cycles to work.
This chapter introduces several different RTOSs—µC/OS, FreeRTOS, Teensy Threads, and Mbed—that you can run on typical SBCs, and it provides an example program ...
