6.7.3.1. 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)
Settings | Description | Default Value |
---|---|---|
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 |
Default network task configuration in uc_tcp_ip_init.c
#define TX_TASK_SIZE (4096u)
#define RX_TASK_SIZE (4096u)
#define TMR_TASK_SIZE (4096u)
static const unsigned TX_TASK_PRIO = 1u;
static const unsigned RX_TASK_PRIO = 3u;
static const unsigned TMR_TASK_PRIO = 5u;
