- FreeRTOS uses its list structure to keep track of tasks for scheduling, and also to implement queues
- 此作業重點在於要將TCB (Task Control Block)找出來
- 由rtenv porting to RTOS
- ls -lh xxxxx --> 檔案詳細資訊

- fio_write(1, buf, count); // Write buffer to fd 1 (stdout, through uart)
- 首先要先移植如下功能至FreeRTOS:
htoa --> ok (與itoa共用一個helper function)
int2str -> ok
str2int -> ok
strlen -> ok
strcmp -> ok
sprintf -> ok
printf -> ok
sprintf -> ok
printf -> ok
- xQueueCreate usage: (from queue.h)
