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 <Foo.h> +#include <Bar.h> + +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/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..99f8578 --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,73 @@ +#include <TinyGPS++.h> +#include <axp20x.h> + +TinyGPSPlus gps; +HardwareSerial GPS(1); +AXP20X_Class axp; + +void setupPower() { + if (!axp.begin(Wire, AXP192_SLAVE_ADDRESS)) { + Serial.println("AXP192 Begin PASS"); + } else { + Serial.println("AXP192 Begin FAIL"); + } + axp.setPowerOutPut(AXP192_LDO2, AXP202_ON); + axp.setPowerOutPut(AXP192_LDO3, AXP202_ON); + axp.setPowerOutPut(AXP192_DCDC2, AXP202_ON); + axp.setPowerOutPut(AXP192_EXTEN, AXP202_ON); + axp.setPowerOutPut(AXP192_DCDC1, AXP202_ON); + axp.setChgLEDMode(AXP20X_LED_OFF); +} + +void setupGps() { + GPS.begin(9600, SERIAL_8N1, 34, 12); //17-TX 18-RX +} + +static void smartDelay(unsigned long ms) +{ + unsigned long start = millis(); + do + { + while (GPS.available()) + gps.encode(GPS.read()); + } while (millis() - start < ms); +} + +void printGpsStatus() { + axp.setChgLEDMode(AXP20X_LED_LOW_LEVEL); + Serial.print("Latitude : "); + Serial.println(gps.location.lat(), 5); + Serial.print("Longitude : "); + Serial.println(gps.location.lng(), 4); + Serial.print("Satellites: "); + Serial.println(gps.satellites.value()); + Serial.print("Altitude : "); + Serial.print(gps.altitude.feet() / 3.2808); + Serial.println("M"); + Serial.print("Time : "); + Serial.print(gps.time.hour()); + Serial.print(":"); + Serial.print(gps.time.minute()); + Serial.print(":"); + Serial.println(gps.time.second()); + Serial.print("Speed : "); + Serial.println(gps.speed.kmph()); + Serial.println("**********************"); + axp.setChgLEDMode(AXP20X_LED_OFF); + smartDelay(1000); + if (millis() > 5000 && gps.charsProcessed() < 10) + Serial.println(F("No GPS data received: check wiring")); +} + +void setup() +{ + Serial.begin(115200); + Wire.begin(21, 22); + setupPower(); + setupGps(); +} + +void loop() +{ + printGpsStatus(); +} diff --git a/test/README b/test/README new file mode 100644 index 0000000..df5066e --- /dev/null +++ b/test/README @@ -0,0 +1,11 @@ + +This directory is intended for PIO 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.
