188.8.131.52. Network Task Configuration
In this example design, the µC/TCP-IP stack has three configurable tasks, the Receive task, the Transmit De-allocation task and the Timer task. Each task is configured with its own task priority and task stack size.
In order to place a task at higher priority, you have to register it with a lower value, and vice versa. The third-party vendor recommends configuring the task priorities as listed below for optimum performance.
- Network Transmit (TX) De-allocation task (Highest priority)
- Network timer task
- Network Receive (RX) task (Lowest Priority)
|TX_TASK_PRIO||Network TX De-allocation Task Priority||1u|
|RX_TASK_PRIO||Network RX Task Priority||3u|
|TMR_TASK_PRIO||Network Timer Task Priority||5u|
|TX_TASK_SIZE||Network TX De-allocation Task Stack Size||4096u|
|RX_TASK_SIZE||Network RX Task Stack Size||4096u|
|TMR_TASK_SIZE||Network Timer Task Stack Size||4096u|
