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..6ce1797 --- /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:pro8MHzatmega328] +platform = atmelavr +board = pro8MHzatmega328 +framework = arduino +extra_scripts = extra_script.py +upload_protocol = custom +build_flags = -Wall -O3 \ No newline at end of file diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..30a2d0a --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,99 @@ +#include + +static const uint8_t PORTD_ROWN = 0xFF; +static const uint8_t PORTD_ROW0 = ~((1 << PD0)); +static const uint8_t PORTD_ROW1 = ~((1 << PD3)); +static const uint8_t PORTD_ROW2 = ~((1 << PD1)); + +static const uint8_t OUT_LEN = 2; + +volatile uint8_t output[OUT_LEN]; + +static inline void wait(uint16_t del) { + auto begin = millis(); + while (millis() - begin < del); +} + +static inline void update_output() { + PORTD = PORTD_ROW0; + delayMicroseconds(30); + uint8_t tmp = (PIND >> 4) & 0x0F; + + PORTD = PORTD_ROW1; + delayMicroseconds(30); + tmp |= (PIND & 0xF0); + + output[0] = tmp; + + PORTD = PORTD_ROW2; + delayMicroseconds(30); + output[1] = (PIND >> 4) & 0x0F; + + PORTD = PORTD_ROWN; + delayMicroseconds(30); +} + +volatile uint8_t ctr = 0; +// ISR(SPI_STC_vect) { +// SPDR = output[ctr]; +// ctr = (ctr + 1) % OUT_LEN; +// } + +ISR(PCINT0_vect){ + if (!(PINB & (1 << PB2))) { + while(!(SPSR & (1<
