flexio_uart_int_rb_transfer#
Overview#
The flexio_uart_interrupt_ring_buffer example shows how to use flexio uart driver in interrupt way with RX ring buffer enabled:
In this example, a flexio simulated uart connect to PC through USB-Serial, the board will send back all characters that PC send to the board.
Note: The example echo every 8 characters, so input 8 characters every time.
Supported Boards#
EVK9-MIMX8ULP
Hardware requirements
Micro USB cable
MIMX8ULP-EVK/EVK9 board
J-Link Debug Probe
5V power supply
Personal Computer
Board settings
The example requires connecting the FLEXIO0 pins with the USB2COM pins The connection should be set as follows:
PTA8(J20,10) on base board, TX of USB2COM connected
PTA9(J20,9) on base board, RX of USB2COM connected
GND(J20,7) on base board, Ground of USB2COM connected
Please note this application can’t support running with Linux BSP!
Prepare the Demo
Connect 5V power supply and J-Link Debug Probe to the board, switch SW10 to power on the board.
Connect a micro USB cable between the host PC and the J17 USB port on the target board.
Open a serial terminal with the following settings:
