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..54d68f3 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,17 @@ +; 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:esp12e] +platform = espressif8266 +board = esp12e +framework = arduino +lib_deps = + adafruit/Adafruit MAX31855 library@^1.4.2 + Wire + SPI diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..aca552a --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,40 @@ +#include +#include +#include +#include + +#define CS D8 +Adafruit_MAX31855 thermocouple(CS); +void setup() { + Serial.begin(9600); + while(!Serial) delay(1); + SPI.begin(); + + Serial.println("MAX31855 test"); + delay(500); + Serial.println("sensor init"); + if (!thermocouple.begin()) { + Serial.println("sensor init error"); + while(true) delay(10); + } + + Serial.println("init done"); + +} + +void loop() { + Serial.print(">internal:"); + Serial.println(thermocouple.readInternal()); + + double c = thermocouple.readCelsius(); + if (isnan(c)) { + uint8_t e = thermocouple.readError(); + if (e & MAX31855_FAULT_OPEN) Serial.println("FAULT: thermocouple open"); + if (e & MAX31855_FAULT_SHORT_GND) Serial.println("FAULT: thermocouple short to GND"); + if (e & MAX31855_FAULT_SHORT_VCC) Serial.println("FAULT: thermocouple short to VCC"); + } else { + Serial.print(">tempc:"); + Serial.println(c); + } + delay(1000); +} \ No newline at end of file diff --git a/src/pinout.h b/src/pinout.h new file mode 100644 index 0000000..1141902 --- /dev/null +++ b/src/pinout.h @@ -0,0 +1,11 @@ +#define D0 16 +#define D1 5 +#define D2 4 +#define D3 0 +#define D4 2 +#define D5 14 +#define D6 12 +#define D7 13 +#define D8 15 +#define D9 3 +#define D10 1 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.
