+
+## Installation
+- The library can be found under the name **Gyver433** and installed via the library manager in:
+ - Arduino IDE
+ - Arduino IDE v2
+ - PlatformIO
+- [Download library](https://github.com/GyverLibs/Gyver433/archive/refs/heads/main.zip) .zip archive for manual installation:
+ - Unzip and put in *C:\Program Files (x86)\Arduino\libraries* (Windows x64)
+ - Unzip and put in *C:\Program Files\Arduino\libraries* (Windows x32)
+ - Unpack and put in *Documents/Arduino/libraries/*
+ - (Arduino IDE) automatic installation from .zip: *Sketch/Include library/Add .ZIP library…* and specify the downloaded archive
+- Read more detailed instructions for installing libraries [here] (https://alexgyver.ru/arduino-first/#%D0%A3%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%B2%D0%BA%D0%B0_%D0%B1%D0%B8%D0%B1%D0 %BB%D0%B8%D0%BE%D1%82%D0%B5%D0%BA)
+
+
+## Interface
+- Before sending data there is a clock pulse, *TRAIN* ms
+- Next start impulse, *START* ms, LOW
+- Data is encoded by pulse length
+- Terminates the sending of a stop pulse, *TRAIN* ms
+
+
+
+
+## Connection
+
+Transmitters:
+- SYN115, small chip: 1.8-3.6V, max. speed 8000
+- FS1000A: 3-12V, max. speed 10000
+- WL102-341: 2.0-3.6V, max. speed 6000
+
+Receivers:
+- SYN480R, large chip: 3.3-5.5V
+- MX-RM-5V (RF-5V): 5V
+- RX470 (WL101-341): 3-5V
+
+
+
+
+
+## Initialization
+```cpp
+// === TRANSMITTER ===
+Gyver433_TX tx;
+Gyver433_TX tx;
+
+// === RECEIVER ===
+Gyver433_RX rx;
+Gyver433_RX rx;
+Gyver433_RX rx;
+
+// pin: digital pin
+// buffer: buffer size in bytes, default 64
+// CRC: data integrity check: G433_CRC8 (reliable), G433_XOR (light), G433_NOCRC (disabled). By default G433_CRC8
+```
+
+
+## Usage
+```cpp
+// ========= Gyver433_TX =========
+void sendData(T&data); // send data of any type (CRC added automatically)
+void write(uint8_t* buf, uint8_t size); // send an array of bytes of the specified size (no CRC added)
+
+// ========= Gyver433_RX =========
+// receive in interrupt
+void tickISR(); // receive ticker to call in CHANGE interrupt
+uint8_t tickISRraw(); // manual reception in CHANGE interrupt. Returns 1 (beginning of reception), 2 (byte received), 3 (end of packet)
+
+// receive in loop
+uint16_t tick(); // non-blocking receive. Returns the number of successfully received bytes
+uint16_t tickWait(); // blocking receive. Returns the number of successfully received bytes
+
+bool readData(T&data); // read the buffer into any data type (into the specified penexchange)
+uint16_t getSize(); // get the size of the received data
+uint16_t gotData(); // will return the number of bytes successfully received in tickISR() (see isr_rx example)
+uint8_t getRSSI(); // get reception quality (percentage of successful transmissions 0.. 100)
+
+uint8_tbuffer[]; // access to the receive buffer
+uint8_t byteBuf; // access to the received byte buffer
+
+// ============= CRC ==============
+// you can use built-in functions to generate a CRC byte for manually packing packets
+uint8_t G433_crc8(uint8_t *buffer, uint8_t size); // manual CRC8
+uint8_t G433_crc_xor(uint8_t *buffer, uint8_t size); // manual CRC XOR
+
+// ====== DEFINE-SETTINGS ======
+// call before linking the library
+#define G433_FAST // [TX] fast sync for green modules
+#define G433_MEDIUM // [TX] average timing when sent to SYN480R OVER 400ms (active by default)
+#define G433_SLOW // [TX] long sync when sent to SYN480R LESS than 400ms
+#define G433_SPEED 1000 // [RX/TX] speed, should be the same on RX and TX, 100-10000 bps, default 2000 bps
+#define G433_RSSI_COUNT 8 // [RX] number of successfully received packets for RSSI calculation (default 8)
+#define G433_CUT_RSSI // [RX] remove RSSI calculation from code (save some memory)
+```
+
+### Receiver operation without interruption
+To receive data, it is enough to call the `tick()` method in the main loop, it polls the radio pin itself.
+- If there are blocking places in the program and loop() is executed with delays - there will be data loss
+- For a more reliable reception, it is recommended to call `tickWait()`, it blocks the execution of the code for the duration of the reception.
+
+### Receiver operation with interrupts
+It is recommended to use the CHANGE interrupt technique by calling `tickISR()` in it.
+Then the reception will be asynchronous and will work even in the loaded program.
+- If the standard interrupt pins are not enough, you can use PCINT. Manually or withLibraries https://github.com/NicoHood/PinChangeInterrupt
+
+
+## Examples
+See **examples** for other examples!
+### Sending
+```cpp
+#include
+Gyver433_TX<2>tx; // specified pin
+
+void setup() {
+}
+
+chardata[] = "Hello from #xx"; // string to send
+byte count = 0; // counter to send
+
+void loop() {
+ // add counter to string
+ data[12] = (count / 10) + '0';
+ data[13] = (count % 10) + '0';
+ if (++count >= 100) count = 0;
+ tx.sendData(data);
+ delay(100);
+}
+```
+
+### Receive in interrupt
+```cpp
+#include
+Gyver433_RX<2, 20> rx; // specified pin and buffer size
+
+void setup() {
+ Serial.begin(9600);
+ attachInterrupt(0, isr, CHANGE); // interrupt radio pin by CHANGE
+}
+
+// spec. ticker is called in interrupt
+void isr() {
+ rx.tickISR();
+}
+
+void loop() {
+ if (rx.gotData()) { // if more than 0 successfully received
+ Serial.write(rx.buffer, rx.size); // output
+ Serial.println();
+ }
+ delay(50); // simulate loaded code
+}
+```
