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..8c9c29c --- /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..089ee04 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,14 @@ +; 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:digispark-tiny] +platform = atmelavr +board = digispark-tiny +framework = arduino diff --git a/src/AnalogReadRangeTest.cpp b/src/AnalogReadRangeTest.cpp new file mode 100644 index 0000000..8f838c0 --- /dev/null +++ b/src/AnalogReadRangeTest.cpp @@ -0,0 +1,52 @@ +#include +// JTR 2020-09-06: Doesn't work yet... + +//#define LED_BUILTIN 1 + +int sensorPin = 7; // select the input pin for the potentiometer +int ledPin = 1; // select the pin for the LED + +int minSens = 32767; +int maxSens = 0; + +bool isInit=true; // the "millis() function will overflow after 50 days, therefore using a flag..." + +void setup() { + pinMode(ledPin, OUTPUT); + pinMode(sensorPin, INPUT); + //Serial.begin(115200); + //delay(1000); // give me time to bring up serial monitor + //Serial.println("ESP32"); +} + +void loop() { + // read the value from the sensor: + int sensorValue = analogRead(sensorPin); + if (sensorValue > maxSens) { maxSens=sensorValue; } + if (sensorValue < minSens) { minSens=sensorValue; } + // stop the program for milliseconds: + + double diff=(double)(sensorValue-minSens+1)/(double)(maxSens-minSens+1); + + if ((isInit) && (millis() < 1000*30)){ + digitalWrite(ledPin, HIGH); + delay(diff*100); + digitalWrite(ledPin, LOW); + } else { + isInit=false; + } + + if ((diff > 0.1) && (!isInit)) { + for (int i=0;i<60*5;i++){ + // looks like really long delays are causing the thing to crash, therefore do something in the loop ;) + digitalWrite(ledPin, LOW); + digitalWrite(ledPin, HIGH); + + delay(1000); + } + } else { + digitalWrite(ledPin, LOW); + } + + delay(50); +} diff --git a/test/README b/test/README new file mode 100644 index 0000000..e7d1588 --- /dev/null +++ b/test/README @@ -0,0 +1,11 @@ + +This directory is intended for PlatformIO 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.
