title: RTOS Datalogger example
body: <p>I'm trying to develop a datalogger on a Cortex M0 (LPC11U14), and I was thinking of using a real-time OS like FreeRTOS, so that I can have one low-priority task that writes the data to SD, and multiple higher-priority timers that fetch the sensor data.</p>
  
  <p>Does anyone know of any code examples that can serve as a reference design? I know how to create tasks/timers, but I'm interested in efficient ways to pass the data from the timers to the write-task. And I'm hestitant to re-invent the wheel, if there already exists a good datalogger project which can serve as a codebase?</p>
