Arduino Serial Communication Crc
README.md CRC32 Description An Arduino library for calculating a CRC32 checksum. Features. Calculate the CRC32 checksum with minimal memory overhead. Calculate the CRC32 checksum as a stream or using buffered data. Calculate the CRC32 checksum of any arbitrary data type. Background A cyclic redundancy check (CRC) is often used to verify data integrity.
The CRC32 algorithm is a common way to quickly produce a small, repeatable hash representing an arbitrary block of data. It is often used to verify data packet integrity during serial or network communication. Use The CRC32 checksum can be calculated on-the-fly with no buffering or the user can pass a complete data buffer.
Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART): Serial.
It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB. Thus, if you use these functions, you cannot also use pins 0 and 1 for digital input or output. You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board.

Communication Protocol Best Practices and Patterns. Nearly the same quality as CRC but is much easier to. Arduino Micro serial communication is not working. I am trying to interface with an EPOS2 motor controller over RS232 Serial with an Arduino Duemilanove (because it's what I had lying around) Arduino serial.
Arduino Serial Communication
Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin. The Arduino Mega has three additional serial ports: Serial1 on pins 19 (RX) and 18 (TX), Serial2 on pins 17 (RX) and 16 (TX), Serial3 on pins 15 (RX) and 14 (TX). To use these pins to communicate with your personal computer, you will need an additional USB-to-serial adaptor, as they are not connected to the Mega’s USB-to-serial adaptor.
To use them to communicate with an external TTL serial device, connect the TX pin to your device’s RX pin, the RX to your device’s TX pin, and the ground of your Mega to your device’s ground.
