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..3420e45 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,18 @@ +; 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:esp01_1m] +platform = espressif8266 +board = esp01_1m +framework = arduino +lib_deps = + adafruit/Adafruit IS31FL3731 Library@^2.0.0 + adafruit/Adafruit GFX Library@^1.11.3 +monitor_speed = 9600 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..4d82432 --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,112 @@ +#include +#include +#include +#include +#include + +using namespace std; + +const char* HOSTNAME="led_test"; +const char* SSID="ncc74656"; +const char* PSK="Rw7qfY5tmtaWbXaWQ5aMSRkF"; + +#define NUM_SCREENS 2 +#define BRIGHTNESS 8 + +Adafruit_IS31FL3731 matrix0 = Adafruit_IS31FL3731(); +#if NUM_SCREENS>=2 +Adafruit_IS31FL3731 matrix1 = Adafruit_IS31FL3731(); +#endif +#if NUM_SCREENS>=3 +Adafruit_IS31FL3731 matrix2 = Adafruit_IS31FL3731(); +#endif +#if NUM_SCREENS>=4 +Adafruit_IS31FL3731 matrix3 = Adafruit_IS31FL3731(); +#endif + +void setup() { + // set up I2C + Wire.pins(0,2); // SDA on GPIO0, SCL on GPIO2 + Wire.begin(0,2); + + // // connect to network + // WiFi.hostname(HOSTNAME); + // WiFi.begin(SSID, PSK); + // while (WiFi.status()!=WL_CONNECTED) + // delay(500); + + // connect to display(s) + if (! matrix0.begin(0x74)) + while (1); + #if NUM_SCREENS>=2 + if (! matrix1.begin(0x75)) + while (1); + #endif + #if NUM_SCREENS>=3 + if (! matrix2.begin(0x76)) + while (1); + #endif + #if NUM_SCREENS>=4 + if (! matrix3.begin(0x77)) + while (1); + #endif +} + +void loop() { + + String msg="The quick brown fox jumps over the lazy dog."; + //String msg=" Hellorld!
