<p>void user_init(void) is the entrance function of the application. </p><dl class="section attention"><dt>Attention</dt><dd>1. It is recommended that users set the timer to the periodic mode for periodic checks. </dd>
|
||
|
|
<dd>
|
||
|
|
(1). In freeRTOS timer or os_timer, do not delay by while(1) or in the manner that will block the thread. </dd>
|
||
|
|
<dd>
|
||
|
|
(2). The timer callback should not occupy CPU more than 15ms. </dd>
|
||
|
|
<dd>
|
||
|
|
(3). os_timer_t should not define a local variable, it has to be global varialbe or memory got by malloc.</dd>
|
||
|
|
<dd>
|
||
|
|
2. Since esp_iot_rtos_sdk_v1.0.4, functions are stored in CACHE by default, need not be added ICACHE_FLASH_ATTR any more. The interrupt functions can also be stored in CACHE. If users want to store some frequently called functions in RAM, please add IRAM_ATTR before functions' name.</dd>
|
||
|
|
<dd>
|
||
|
|
3. Network programming use socket, please do not bind to the same port. </dd>
|
||
|
|
<dd>
|
||
|
|
(1). If users want to create 3 or more than 3 TCP connections, please add "TCP_WND = 2 x TCP_MSS;" in "user_init".</dd>
|
||
|
|
<dd>
|
||
|
|
4. Priority of the RTOS SDK is 15. xTaskCreate is an interface of freeRTOS. For details of the freeRTOS and APIs of the system, please visit <a href="http://www.freertos.org">http://www.freertos.org</a> </dd>
|
||
|
|
<dd>
|
||
|
|
(1). When using xTaskCreate to create a task, the task stack range is [176, 512]. </dd>
|
||
|
|
<dd>
|
||
|
|
(2). If an array whose length is over 60 bytes is used in a task, it is suggested that users use malloc and free rather than local variable to allocate array. Large local variables could lead to task stack overflow. </dd>
|
||
|
|
<dd>
|
||
|
|
(3). The RTOS SDK takes some priorities. Priority of the pp task is 13; priority of precise timer(ms) thread is 12; priority of the TCP/IP task is 10; priority of the freeRTOS timer is 2; priority of the idle task is 0. </dd>
|
||
|
|
<dd>
|
||
|
|
(4). Users can use tasks with priorities from 1 to 9. </dd>
|
||
|
|
<dd>
|
||
|
|
(5). Do not revise FreeRTOSConfig.h, configurations are decided by source code inside the RTOS SDK, users can not change it. </dd></dl>
