You request the use of a +header file in your project source file (C, C++, etc) located in `src` folder +by including it, with the C preprocessing directive `#include'. + +```src/main.c + +#include "header.h" + +int main (void) +{ + ... +} +``` + +Including a header file produces the same results as copying the header file +into each source file that needs it. Such copying would be time-consuming +and error-prone. With a header file, the related declarations appear +in only one place. 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 usual convention is to give header files names that end with `.h'. +It is most portable to use only letters, digits, dashes, and underscores in +header file names, and at most one dot. + +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..6debab1 --- /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 executable file. + +The source code of each library should be placed in a an own separate directory +("lib/your_library_name/[here are source files]"). + +For example, see a structure of the following two libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional, 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 + +and a contents of `src/main.c`: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +PlatformIO Library Dependency Finder will find automatically dependent +libraries 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..edb3dd1 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,17 @@ +; 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:nanoatmega328] +platform = atmelavr +board = nanoatmega328 +framework = arduino +lib_deps = + adafruit/Adafruit SH110X@^2.1.11 + adafruit/Adafruit GFX Library@^1.11.11 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..fcdee17 --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,81 @@ +#include +#include +#include +#include +#include + +#define i2c_Address 0x3c //initialize with the I2C addr 0x3C Typically eBay OLED's +#define SCREEN_WIDTH 128 // OLED display width, in pixels +#define SCREEN_HEIGHT 64 // OLED display height, in pixels +#define OLED_RESET -1 // QT-PY / XIAO + +Adafruit_SH1106G display = Adafruit_SH1106G(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET); +int VoltPin=A1; +float Spannung; +float R1=30000; +float R2=7500; +float Vout; +float Vin; + +const byte address[6] = "00001"; + +void Startbildschirm(){ + display.clearDisplay(); //Display löschen + display.setTextColor(SH110X_WHITE); //Textfarbe + display.setTextSize(2); //Textgröße + display.setCursor(25,5); + display.print("Battery"); + display.setCursor(35,35); + display.print("Guard"); + display.display(); +} + +void Anzeige(){ + display.clearDisplay(); //Display löschen + display.setTextColor(SH110X_WHITE); //Textfarbe + display.setTextSize(2); //Textgröße + display.setCursor(20,5); + display.print("Voltage:"); + display.setCursor(30,35); + display.print(Vin); + display.setCursor(100,35); + display.print("V"); + display.display(); +} + +void Anzeige2(){ + display.clearDisplay(); //Display löschen + display.setTextColor(SH110X_WHITE); //Textfarbe + display.setTextSize(2); //Textgröße + display.setCursor(20,5); + display.print("Battery"); + display.setCursor(35,35); + display.print("low!"); + display.display(); +} + +void setup() { + Serial.begin(9600); + + Wire.begin(); //SDA -> A4, CLK -> A5 + display.begin(i2c_Address, true); + Startbildschirm(); + delay(5000); + + pinMode(VoltPin,INPUT); +} + +void loop() { + Spannung=analogRead(VoltPin); + Vout=Spannung*5/1024; + Vin=Vout/(R2/(R1+R2)); + + while(Vin>10.5){ + Spannung=analogRead(VoltPin); + Vout=Spannung*5/1024; + Vin=Vout/(R2/(R1+R2)); + Anzeige(); + delay(1000); + } + Anzeige2(); +} 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.
