| Overview |
| ======== |
| The uart_auto_baudrate_detect example shows how to use uart auto baud rate detect feature: |
| |
| In this example, one uart instance connect to PC through uart. First, we should send characters a or A to board. |
| The boars will set baud rate automatic. After baud rate has set, the board will send back all characters that PC |
| send to the board. |
| |
| Toolchain supported |
| =================== |
| - IAR embedded Workbench 8.50.1 |
| - GCC ARM Embedded 9.2.1 |
| |
| Hardware requirements |
| ===================== |
| - Micro USB cable |
| - MIMX8MQ6-EVK board |
| - J-Link Debug Probe |
| - 12V power supply |
| - Personal Computer |
| |
| Board settings |
| ============== |
| No special settings are required. |
| |
| |
| |
| Prepare the Demo |
| ================ |
| 1. Connect 12V power supply and J-Link Debug Probe to the board, switch SW701 to power on the board |
| 2. Connect a USB cable between the host PC and the J1701 USB port on the target board. |
| 3. Open a serial terminal with the following settings: |
| - 115200 baud rate |
| - 8 data bits |
| - No parity |
| - One stop bit |
| - No flow control |
| 4. Download the program to the target board. |
| 5. Launch the debugger in your IDE to begin running the demo. |
| |
| |
| Running the demo |
| ================ |
| Set any baud rate in your terminal, and send character a or A to board, then |
| When the demo runs successfully, the log would be seen on the debug terminal like: |
| |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| UART has detect one character A |
| Baud rate has been set automatic! |
| Board will send back received characters |
