I'm using my Arduino to make a speaker-like device. Instead of sound, it receives the beat of the song, thus the data comes in an array of floats. Each item in the array is a timestamp, an LED is turned on based on that value.
For example, [0.01,0.53] means sleep 0.01s, turn on LED, pop off 0.01, sleep 0.53 seconds, turn on LED.
I have two questions:
1)How can I receive data and pop off data at the same time? I'm thinking I can send maybe 10 items for the Arduino to buffer at one time, and repeat that until the whole action is done. The popping off action is time sensitive, so I can't do it sequentially. How can I run both functions at once? Are arduinos capable of multithreading?
2)I'm using an arduino with BLE and sending over the data using serial.read() from an iPhone. and the device only allows 18 bytes to be sent over at one time and it is very slow. What other methods can I use? I need to send 18 bytes from my iPhone, wait 2 seconds, then send it again otherwise the arduino treats it as one single send and the other values are not sent over.
3)Is there a better way of doing all of this that I'm missing?
Thank you very much.
