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..c53aba9 --- /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:pico] +platform = https://github.com/maxgerhardt/platform-raspberrypi.git +board = pico +framework = arduino +board_build.core = earlephilhower +lib_deps = + https://github.com/adafruit/Adafruit-GFX-Library.git + https://github.com/adafruit/Adafruit_SSD1306.git + https://github.com/sekigon-gonnoc/Pico-PIO-USB.git diff --git a/src/main.cc b/src/main.cc new file mode 100644 index 0000000..4a0cdcd --- /dev/null +++ b/src/main.cc @@ -0,0 +1,77 @@ +#include +#include +#include + +#include +#include + +#include +#include + +static Adafruit_SSD1306 display(128, 32, &Wire1, /* OLED_RESET */ -1); +static int i = 0; + +void feedback(void *) { + vTaskCoreAffinitySet(nullptr, 1 << 1); + // vTaskDelay(1000 / port_TICK_MS); + + pinMode(18, OUTPUT_12MA); + pinMode(19, OUTPUT_12MA); + + while (true) { + display.clearDisplay(); + display.setCursor(0, 0); + display.print("Sun input emulator"); + display.setCursor(0, 12); + display.print("CAP CMP SCR NUM"); + display.drawRoundRect(0, 20, 18, 12, 4, SSD1306_WHITE); + display.drawRoundRect(30, 20, 18, 12, 4, SSD1306_WHITE); + display.drawRoundRect(60, 20, 18, 12, 4, SSD1306_WHITE); + display.drawRoundRect(90, 20, 18, 12, 4, SSD1306_WHITE); + display.display(); + + digitalWrite(LED_BUILTIN, HIGH); + // digitalWrite(18, LOW); + // digitalWrite(19, HIGH); + delay(420); + digitalWrite(LED_BUILTIN, LOW); + // digitalWrite(18, HIGH); + // digitalWrite(19, LOW); + delay(420); + // Serial.println(i++); + } + + vTaskDelete(nullptr); +} + +void usb(void *) { + while (true); + + vTaskDelete(nullptr); +} + +void setup() { + // needs to be done manually when using FreeRTOS + Serial.begin(); + + pinMode(LED_BUILTIN, OUTPUT); + + // Wire1.setSDA(31); + // Wire1.setSCL(32); + display.begin(SSD1306_SWITCHCAPVCC, /* SCREEN_ADDRESS */ 0x3C); + display.setRotation(2); + display.cp437(true); + display.setTextColor(SSD1306_WHITE, SSD1306_BLACK); + display.clearDisplay(); + + xTaskCreate(feedback, "feedback", 2048, nullptr, 1, nullptr); + xTaskCreate(usb, "usb", 2048, nullptr, 1, nullptr); + + while (!Serial); + Serial.write("\r\n\r\nSun input emulator"); +} + +void loop() {} + +// void serialEvent() { +// } 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.
