If they need to be changed, they can be changed in one +place, and programs that include the header file will automatically use the +new version when next recompiled. The header file eliminates the labor of +finding and changing all the copies as well as the risk that a failure to +find one copy will result in inconsistencies within a program. + +In C, the convention is to give header files names that end with `.h'. + +Read more about using header files in official GCC documentation: + +* Include Syntax +* Include Operation +* Once-Only Headers +* Computed Includes + +https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html diff --git a/lib/README b/lib/README new file mode 100644 index 0000000..9379397 --- /dev/null +++ b/lib/README @@ -0,0 +1,46 @@ + +This directory is intended for project specific (private) libraries. +PlatformIO will compile them to static libraries and link into the executable file. + +The source code of each library should be placed in a separate directory +("lib/your_library_name/[Code]"). + +For example, see the structure of the following example libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html +| | +| |--Foo +| | |- Foo.c +| | |- Foo.h +| | +| |- README --> THIS FILE +| +|- platformio.ini +|--src + |- main.c + +Example contents of `src/main.c` using Foo and Bar: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +The PlatformIO Library Dependency Finder will find automatically dependent +libraries by scanning project source files. + +More information about PlatformIO Library Dependency Finder +- https://docs.platformio.org/page/librarymanager/ldf.html diff --git a/platformio.ini b/platformio.ini new file mode 100644 index 0000000..8ba220f --- /dev/null +++ b/platformio.ini @@ -0,0 +1,14 @@ +; PlatformIO Project Configuration File +; +; Build options: build flags, source filter +; Upload options: custom upload port, speed and extra flags +; Library options: dependencies, extra library storages +; Advanced options: extra scripting +; +; Please visit documentation for the other options and examples +; https://docs.platformio.org/page/projectconf.html + +[env:nanoatmega328new] +platform = atmelavr +board = nanoatmega328new +framework = arduino diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..08e2cfd --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,34 @@ +#include + +#define LED 13 + +double f = 0.1; +double t = 0.0; +double Ts = 0.25; + +void senddata(double _t, double _f, double _A=1) { + + float _y; + + _y = _A * sin(2 * PI * _f * _t); + + Serial.print(_t); + Serial.print(","); + Serial.println(_y); + +} + +void setup() { + + Serial.begin(115200); + +} + +void loop() { + + senddata(t, f); + delay(Ts * 1000); + + t = t + Ts; + +} diff --git a/src/readdata.py b/src/readdata.py new file mode 100644 index 0000000..c917884 --- /dev/null +++ b/src/readdata.py @@ -0,0 +1,97 @@ +import matplotlib.pyplot as plt +import serial +import glob +import numpy as np + +print('Hello, World!') + +# Get Arduino Port +arduinoports = glob.glob('/dev/*USB*') +arduinoport = arduinoports[0] + +print(arduinoports) + +# Open Arduino Port +arduino = serial.Serial(arduinoport, 115200) +arduino.close() +arduino.open() + +#initiate the data +tdata = np.array([]) +ydata = np.array([]) + +# create the plot +plt.ion() +fig = plt.figure(1) +fig.clf() +ax = fig.add_subplot(111) + +dataline, = ax.plot(tdata, ydata, 'o') +ax.set_ylim([-1.5, 1.5]) +ax.set_xlim([0,20]) + +# plt.show() + +#define the plot update function +def plotupdate(_t, _y): + + + ax.clear() + + # dataline.set_xdata(_t) + #dataline.set_ydata(_y) + ax.plot(ydata) + + + #ax.relim() + #ax.autoscale_view() + + fig.canvas.draw() + fig.canvas.flush_events() + + plt.pause(0.05) + + +while True: + + #read the raw data from the arduino + rawdata = arduino.readline() + #rawdata = arduino.read_until(b'\n') + + print(rawdata) + + splitdata = rawdata.decode().split(',') + + tdata = np.append(tdata, float(splitdata[0])) + ydata = np.append(ydata, float(splitdata[1])) + + tdata = tdata[-100:] + ydata = ydata[-100:] + + #plotupdate(tdata, ydata) + + #dataline.set_xdata(tdata[-1]) + #dataline.set_ydata(ydata[-1]) + + ax.clear() + ax.plot(tdata, ydata, 'o') + + ax.relim() + #ax.autoscale_view() + + #ax.set_xlim([0, 100]) + + fig.canvas.draw() + fig.canvas.flush_events() + + plt.pause(0.05) + + + + + + + + + + diff --git a/test/README b/test/README new file mode 100644 index 0000000..9b1e87b --- /dev/null +++ b/test/README @@ -0,0 +1,11 @@ + +This directory is intended for PlatformIO Test Runner and project tests. + +Unit Testing is a software testing method by which individual units of +source code, sets of one or more MCU program modules together with associated +control data, usage procedures, and operating procedures, are tested to +determine whether they are fit for use.
