| Overview |
| ======== |
| This document explains the freertos_event example. It shows how task waits for an event (defined set |
| of bits in event group). This event can be set by any other process or interrupt in the system. |
| |
| The example application creates three tasks. Two write tasks write_task_1 and write_task_2 |
| continuously setting event bit 0 and bit 1. |
| |
| Read_task is waiting for any event bit and printing actual state on console. Event bits are |
| automatically cleared after read task is entered. |
| |
| Three possible states can occurre: |
| Both bits are set.z |
| Bit B0 is set. |
| Bit B1 is set. |
| |
| |
| 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 |
| ================ |
| After the board is flashed the Tera Term will start printing the state of event bits. |
| |
| Example output: |
| Bit B1 is set. |
| Bit B0 is set. |
| Bit B1 is set. |
| Bit B0 is set. |
| Bit B1 is set |
