  1. Just as an update, in the same sketch as the problem sketch above if I call these functions in my setup the connection is made and data is published. void setup() { Serial.begin(9600); MyCounter.start(); // start counter wifiConnect(); wifiPrintout(); } Results in the following Serial Monitor output: Start WiFi ......... SSID: HomeWiFi IP Address: 2250 testA testLoop Publishing successful! testB Why is it when I call the same function in the loop that it would cause this to hang up? Essentially I need to get this function working in my main loop.
  2. Hello all, I have recently gotten two separate functions working but when combining I am having trouble publishing data to an MQTT broker. The command "client.connect("LaunchPadClient");" is causing my launchpad to stop operation. I am using the MSP4305529 & CC3100. The libraries I have combined for this particular project are: CounterLib_t WiFi.h SPI.h PubSubClient.h The code where the problem portion occurs: void wifiPrintout() { // read the input on analog pin: int sensorValue = (analogRead(24)); Serial.println(sensorValue); // convert into to char array Str
  3. Thanks, I have been using Node-Red up until recently because I wanted a way of actually storing data but am currently looking into pulling data from Node-Red.
  4. Hello all, I am looking to stream sensor data and back it up preferably in the cloud where I can later analyze the data. I'm currently using the CC3100+MSP430. I have yet to get Temboo working properly, though it looks to be exactly what I want. If anyone has had any luck with Temboo or would make any other recommendations I would appreciate the input.
  5. @@Fmilburn This did indeed work . I will update in the other thread with my results after I do some more testing. As it stands right now it appears the data is in 10Hz increments ideally I would like to get this down, I'm sure this was unnecessary with the larger frequencies measured.
  6. @@Fmilburn Yes I am looking for some type of counter that increments by the signal being equal to some threshold. I have revamped my initial question in a new thread seen HERE
  7. Hi everyone, I am looking to write/port code to determine real-time frequency of an input signal (audio signal no greater than 4kHz for my needs) on my MSP430 F5529. After looking over interrupts/timers I feel I have a better sense of how this will tie into this project. But I am still at a bit of a loss on the coding portion when it comes to having interrupts occur at my desired frequency. High level abstract of my desired algorithm is as follows (although I am open to any ideas): A ) Enters Loop B ) Input analog signal (audio tones) crosses some set threshold (not zero due to
  8. Is there a way of sampling an analog input (audio signal) and processing the signal with the on board ADC for input into this particular frequency counter on the F5529?
  9. Thank you for the input Fmilburn. I am looking to obtain the real time frequency values from an analog signal (microphone circuit). Considering I am not interested in higher frequency signals (4KHz would be the absolute max I am interested in, needing 8K samples/second) would I still need to utilize the pulses from P1.0. Since I am using the MSP430F5529LP in the link you sent along it says that "you have to use the upper pin of the LED1 jumper to input the signal", so do I have to physically remove this jumper and wire from the pin closer to the inside of the board to one of the pins t
  10. Could anyone offer any info on interrupts and using the internal clock to help determine the frequency?
  11. Hello all, let me start by saying thank you ahead of time for any input. I am looking to take real time (or close to) readings of audio frequencies with my Ti Launchpad. Ideally I want to feed in a periodic signal and look for deviations in the signal. I am only interested in the frequency range of 20Hz - 2KHz. I have been looking at some previous spectrum analyzer projects others have done to display frequency bands which move with corresponding audio signals and have come up with a few questions. I would like to do something similar but output numerical value of the frequency as accurate
