| Overview |
| ======== |
| The gpt_timer project is a simple demonstration program of the SDK GPT driver. It sets up the GPT |
| hardware block to trigger a periodic interrupt after every 1 second. When the GPT interrupt is triggered |
| a message a printed on the UART terminal. |
| |
| 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 is needed. |
| |
| |
| |
| 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 |
| ================ |
| When the example runs successfully, following information can be seen on the terminal: |
| |
| ~~~~~~~~~~~~~~~~~~~~~ |
| |
| Press any key to start the example |
