  1. Why does energia report two com ports? I can't find any info on this. Both ports download correctly but only one supports Serial.print(). I have a Launchpad FR4133. I know that one is a debug port and the other the Application UART, but as far as I can see energia does not support Debug. Code Composer Studio does allow import of energia sketches and debug. I thought energia was meant to be as simple as Arduino. Energia is a much higher level than C or driverlib and is much quicker and accepts C when needed.
  2. The post does refer to Energia. Perhaps I should have posted elsewhere. The question is really about the limitations of using interrupts in Energia. I have code that uses the 3768 crystal in Code Composer Studio and hoped that it was possible to use the 32768Hz crystal with the Real Time Counter in Energia. If a separate library is needed then I suppose RTC counter support is not supported in Energia.
  3. The attach interrupt function works with GPIO pins. I have been able to read and write to the RTC registers. Is it possible to use the attach function to declare isrs for the RTC counter.
  4. Should I have referred to it as P1.0, TXD, LED1, RED_LED or P1_0. The blink sketch just uses RED_LED.
  5. Using the FR4133 launchpad I found that the red led seems to use the serial port. Using the red led as an output stops the serial output.
