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..8ee6d4a --- /dev/null +++ b/platformio.ini @@ -0,0 +1,15 @@ +; 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:blackpill_f103c8] +platform = ststm32 +board = blackpill_f103c8 +framework = arduino +upload_port = stlink diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..026967d --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,79 @@ +#include + +#define LED1 PB14 +#define LED2 PB15 +#define LED3 PA8 +#define BUTTON PA0 + +#define BUTTONDELAY 500 + + +uint8_t patternIndex = 0; +unsigned long buttontimer = 0; +bool buttonFlag = false; +bool patternFlag = false; + + +uint8_t ledpattern[5][3] = { + {1,0,0}, + {0,0,1}, + {0,1,0}, + {0,1,0}, + {0,0,1} +}; + + +void setup() +{ + pinMode(LED1, OUTPUT); + pinMode(LED2, OUTPUT); + pinMode(LED3, OUTPUT); + pinMode(BUTTON, INPUT_PULLUP); +} + +void loop() +{ + unsigned long currentMillis = millis(); + //debounce button + if(!digitalRead(BUTTON)) + { + if(!buttonFlag) + { + //button not detected jet, check timer + if(currentMillis - buttontimer >= BUTTONDELAY) + { + buttonFlag = true; + } + } + } + else + { + //button is not pressed, keep updating the timer + buttonFlag = false; + patternFlag = false; + buttontimer = millis(); + } + + if(buttonFlag) + { + if(!patternFlag) + { + patternIndex++; + if(patternIndex > 5) + { + patternIndex = 0; + } + patternFlag = true; + } + //write pattern to the LEDs + digitalWrite(LED1,!ledpattern[patternIndex][0]); + digitalWrite(LED2,!ledpattern[patternIndex][1]); + digitalWrite(LED3,!ledpattern[patternIndex][2]); + } + else + { + digitalWrite(LED1,1); + digitalWrite(LED2,1); + digitalWrite(LED3,1); + } +} \ No newline at end of file diff --git a/test/README b/test/README new file mode 100644 index 0000000..b94d089 --- /dev/null +++ b/test/README @@ -0,0 +1,11 @@ + +This directory is intended for PlatformIO Unit Testing 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.
