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 convention is to give header files names that end with `.h'. + +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..9379397 --- /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 the executable file. + +The source code of each library should be placed in a separate directory +("lib/your_library_name/[Code]"). + +For example, see the structure of the following example libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional. for 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 + +Example contents of `src/main.c` using Foo and Bar: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +The PlatformIO Library Dependency Finder will find automatically dependent +libraries by 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..e356bcb --- /dev/null +++ b/platformio.ini @@ -0,0 +1,23 @@ +; 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 = jgromes/RadioLib@^7.4.0 + +[env:pico2] +platform = https://github.com/maxgerhardt/platform-raspberrypi.git +board = rpipico2 +framework = arduino +board_build.core = earlephilhower +lib_deps = jgromes/RadioLib@^7.4.0 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..fe9648f --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,120 @@ +/* + Simple test of a LoRa RA-01 module usign RadioLib on an Arduino 101 +*/ + +#include +#include +#include + + +#define RADIO_CS_PIN 6 // on-device: NSS +#define RADIO_IRQ_PIN 8 // on-device: DIO0 +#define RADIO_RST_PIN 7 // on-device: RST +#define SCK_PIN 2 +#define MISO_PIN 4 +#define MOSI_PIN 3 + +#define LOCKUP(x) do{Serial.println(x);delay(1000);}while(true) + + +const bool TRANSMIT_FIRST = true; + +SX1278 radio = new Module(RADIO_CS_PIN, RADIO_IRQ_PIN, RADIO_RST_PIN); +int tx_state = RADIOLIB_ERR_NONE; +bool tx_flag = false; +volatile bool operation_done = false; + + +void operation_done_cb(void) +{ + operation_done = true; +} + + +SPISettings spisettings(1000000, MSBFIRST, SPI_MODE0); + +void setup() +{ + Serial.begin(9600); + + SPI.setSCK(SCK_PIN); + SPI.setTX(MOSI_PIN); + SPI.setRX(MISO_PIN); + SPI.begin(true); + + Serial.print(F("[SX1278] Initializing ...
