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.

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/250119-085716-esp32-c6-devkitc-1/lib/README b/250119-085716-esp32-c6-devkitc-1/lib/README new file mode 100644 index 0000000..2593a33 --- /dev/null +++ b/250119-085716-esp32-c6-devkitc-1/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 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/250119-085716-esp32-c6-devkitc-1/platformio.ini b/250119-085716-esp32-c6-devkitc-1/platformio.ini new file mode 100644 index 0000000..5d75a23 --- /dev/null +++ b/250119-085716-esp32-c6-devkitc-1/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:ESP_NOW_Rc_Car_Sender] +platform = espressif32 +board = esp32-c6-devkitc-1 +framework = arduino +lib_extra_dirs = ~/Documents/Arduino/libraries +serial_speed = 115200 +upload_protocol = esptool diff --git a/250119-085716-esp32-c6-devkitc-1/src/ESP_NOW_Rc_Car_Sender.ino b/250119-085716-esp32-c6-devkitc-1/src/ESP_NOW_Rc_Car_Sender.ino new file mode 100644 index 0000000..34e6126 --- /dev/null +++ b/250119-085716-esp32-c6-devkitc-1/src/ESP_NOW_Rc_Car_Sender.ino @@ -0,0 +1,68 @@ +#include "Arduino.h" +#include +#include + +// REPLACE WITH YOUR RECEIVER MAC Address +uint8_t broadcastAddress[] = {0xF0, 0xF5, 0xBD, 0x07, 0x81, 0x7C}; + +// Structure example to send data +// Must match the receiver structure +typedef struct struct_message { + int JoyX; + int JoyY; +} struct_message; + +// Create a struct_message called myData +struct_message myNowMessage; +esp_now_peer_info_t peerInfo; + +int JoyPinX = A1; +int JoyPinY = A4; +// callback when data is sent +void OnDataSent(const uint8_t *mac_addr, esp_now_send_status_t status) { + Serial.print("\r\nLast Packet Send Status:\t"); + Serial.println(status == ESP_NOW_SEND_SUCCESS ?
