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..8c9c29c --- /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..c877c22 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,19 @@ +; 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:esp32doit-devkit-v1] +platform = espressif32 +board = esp32doit-devkit-v1 +monitor_speed = 115200 +framework = arduino +lib_deps = + adafruit/Adafruit SSD1306@2.3.1 + adafruit/Adafruit GFX Library@^1.10.0 + adafruit/Adafruit BusIO@^1.4.2 diff --git a/src/Works_SimpleTest_ESP32.cpp b/src/Works_SimpleTest_ESP32.cpp new file mode 100644 index 0000000..39f2d45 --- /dev/null +++ b/src/Works_SimpleTest_ESP32.cpp @@ -0,0 +1,64 @@ +/* JTR 2020-09-05: This works now; Some pointers: + * 1) The library must have changed and the first 2 parameters of the display constructor are width and height.. + * 2) The default configuration seems to be that one hast to use the "HSPI" ports rather than the VSPI! + */ + +#include +#include +#include +#include +#include + +#define SCREEN_WIDTH 128 // OLED display width, in pixels +#define SCREEN_HEIGHT 64 // OLED display height, in pixels + +// Declaration for SSD1306 display connected using software SPI (default case): +#define OLED_CLK 14 // OLED: D0 +#define OLED_MOSI 13 // OLED: D1 +#define OLED_RST 22 // OLED: RES +#define OLED_DC 17 // (ESP32-"TX2") OLED: DC +#define OLED_CS 23 // OLED: CS + + +Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT,OLED_MOSI, OLED_CLK, OLED_DC, OLED_RST, OLED_CS); + +void setup() { + + Serial.begin(115200); + delay(1250); + + Serial.println("GO!."); + + if(!display.begin(SSD1306_SWITCHCAPVCC)) { + Serial.println(F("SSD1306 allocation failed")); + for(;;); // Don't proceed, loop forever + } + + + // Show initial display buffer contents on the screen -- + // the library initializes this with an Adafruit splash screen. + display.clearDisplay(); + display.display(); + + display.setTextSize(1); // Normal 1:1 pixel scale + display.setTextColor(SSD1306_WHITE); // Draw white text + display.setCursor(0,0); // Start at top-left corner + display.println(F("Starting...")); + display.display(); + delay(1000); +} + +int i=1; +void loop() { + display.clearDisplay(); + + display.setTextSize(i++); // Normal 1:1 pixel scale + display.setTextColor(SSD1306_WHITE); // Draw white text + display.setCursor(0,0); // Start at top-left corner + display.println(F("GroW")); + display.display(); + + if (i > 5) { i=1; } + delay(200); + Serial.println("GroW."); +} diff --git a/test/README b/test/README new file mode 100644 index 0000000..e7d1588 --- /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.
