ESP32 Arduino Serial Communication 02 - Sends Multiple Data Up to 20 Data, Handle Long Data Packets
The ESP32 microcontroller boasts powerful capabilities for serial communication, making it an ideal choice for projects requiring reliable and efficient data transfer. The ESP32 has three UART interfaces (UART0, UART1, and UART2), allowing it to handle multiple serial devices simultaneously. UART is widely used for communication with devices like sensors, GPS modules, and other microcontrollers. We can configure the baud rate, data bits, parity, and stop bits to tailor the communication to our needs. The ESP32 supports the Arduino framework, which provides easy-to-use libraries for serial communication. For instance, the HardwareSerial class simplifies UART communication.
This is a video demo of serial communication between ESP32 and Arduino Uno. In this video, I demonstrate sending multiple serial data, with a total of up to 20 data. The data types sent are byte, bool, char, and float. I think this is enough to represent other data types.
In this demo video, I use Arduino Uno as a transmitter and ESP32 as a receiver. ESP32 uses Serial2 (Serial Hardware) and Arduino Uno uses Serial Software (pins 10 and 11).
