The LED is attached to pin 13 on Arduino. SparkFun RebBoard with additional LED on pin 12. Requires Bill Greiman's port of Free RTOS to Arduino Porting Marshall Taylor's out-of-synch blinker example The LED on pin 13 flashes every 200 milliseconds, and I've added a second LED on pin 12 that toggles every 210 milliseconds. I've also assigned each of them its own LED, rather than sharing a single LED among them. I'm only running two timed blinkers, rather than three. For the sake of demonstration, I've changed a couple of things. A Quick TourĪs a quick example of RTOS programming, I've adapted MTaylor's 3-channel blinker example. The result should be that the pin 13 LED blinks about twice a second. From the file menu, select file->examples->FreeRTOS_AVR->frBlink On my PC, that's C:\Users\byron.j\Documents\Arduino\libraries. Install the library by copying the folder from /libraries/FreeRTOS_AVR to your local Arduino library directory.Rather than getting deep into RTOS therory or application design, let's jump in and get an RTOS working, then examine some code that uses its facilities.įor these examples, I'm using a RedBoard and Arduino 1.6.5. Moving from plain Arduino to an RTOS is a big conceptual step - big enough that a single blog post isn't going to be a comprehensive introduction. If you're adventurous, he also has Arduino-library versions of ChibiOS and NilRTOS. It seemed to meet my requirements: I've got the Arduino IDE, and from past experience, I knew FreeRTOS is mature, well documented and reasonably full featured. This time around, however, I found exactly what I was looking for: Bill Greiman (the guy behind the SdFat library) has ported FreeRTOS to work as an Arduino Library, with support for both AVR and ARM based boards. It wasn't easy to find an RTOS that ran on the AVR, wasn't broken or incomplete, was well documented, and was compatible with the compliers and debuggers I had available I've done surveys like this in the past, and my findings ranged between disappointing and frustrating. My goal was to have something that I could use on a RedBoard or ProMini, both of which are based on the Atmel ATMega328P, a member of the AVR family. This seemed like an opportune time to do a survey of RTOS, hopefully finding one that could fit on small microcontrollers, and that wouldn't take a lot of effort to get working. I've done a lot of programming with RTOS on larger microcontrollers, like the Motorola 68000 and various ARM7 chips, but hadn't yet used one on an 8-bit micro. ![]() In the comments, several people mentioned that a Real Time Operating System ( RTOS) might be a more flexible and generic solution to the timing and scheduling problem. Last week, my esteemed colleague MTaylor explored a solution to scheduling periodic tasks on Arduino. ![]()
