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..2593a33 --- /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 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..25165b1 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,20 @@ +; 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:nodemcu-32s2] +platform = espressif32 +board = nodemcu-32s2 +board_build.mcu = esp32 +framework = arduino +monitor_speed = 115200 +lib_deps = + mrfaptastic/ESP32 HUB75 LED MATRIX PANEL DMA Display@^3.0.12 + https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA.git + adafruit/Adafruit GFX Library@^1.11.10 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..58d54d0 --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,183 @@ +//#include +#include +#include +#include +#include +#include +#include +const char* ssid = "VSMI-Guest"; +const char* password = "h3ll0vsmi"; + +#define R1_PIN 25 +#define G1_PIN 26 +#define B1_PIN 27 +#define R2_PIN 14 +#define G2_PIN 12 +#define B2_PIN 13 +#define A_PIN 23 +#define B_PIN 22 // Changed from library default +#define C_PIN 5 +#define D_PIN 17 +#define E_PIN 32 // required for 1/32 scan panels, like 64x64px.
