  1. I am trying to run the Firmata library code on my TIVA-C launchpad TM4C123GXL. Firmata located here: https://github.com/energia/Energia/tree/master/libraries/Firmata Now I have followed the instructions on the page, but still get the error when trying to compile the StandardFirmata. The error is : StandardFirmata.cpp.o: In function `setPinModeCallback(unsigned char, int)': StandardFirmata.cpp:(.text._Z18setPinModeCallbackhi+0x5a): undefined reference to `Servo::attached()' StandardFirmata.cpp:(.text._Z18setPinModeCallbackhi+0x1ec): undefined reference to `Servo::attached()' S
  2. Dear Fellows, So I got a new CC3100 Booster Pack, and out of box, decided to try the IOT-MQTT example with energia. While energia did run the basic AnalogSerialRead example perfectly with my potentiometer, I wasnt able to move past that. I got the MQTT code as in the example from the PubSubClient - potentiometer example, and made necessary changes like updating my ssid and pwd, also changed the corresponding pin etc. I compiled and uploaded the code. Upon resetting my TIVA-C TM4C123GXL launchpad, the Serial monitor printed the first message "Start Wifi", and then hung indefintel
  3. I have a TSL235 R light to frequency converter, the datasheet is here: http://www.rhydolabz.com/documents/sensors/TSL235R_LF.pdf. I want to measure the output frequency which is in the range of 250 kHz. I have an ARDUINO Uno and TIVA LaunchPad. How can I interface the sensor with the board for the frequency measurement ? I am not an electronics engineer, so only reading the datasheet doesnt do it for me. |O Page 5 of the datasheet shows the diagram to interface the sensor with an MCU. Is it possible to do with TIVA Launchpad ? Will it be accurate enough ? Any example program for
