UART Events Example

This example shows how to use the UART driver to handle special UART events. It also reads data from UART0 directly, and echoes it to console.

• Compile and load example from terminl running make flash monitor
• Being in 'monotor' type samething to see the UART_DATA events and the typed data displayed.

How to use example

Configure the project

make menuconfig

• Set serial port under Serial Flasher Options.
• make monitor baud rate set to what you set in the example.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

make -j4 flash monitor

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Example Output

• Paste 0123456789 to monitor, the UART DATA event will be received.
