Clarification on Scheduling Algorithms for Task Priority

Posted by KRS

Hi guys I am little confused about a topic I was going through the scheduling algorithms and my question is:

Let’s say I have 2 tasks
Task 1 has higher priority
Task 2 has lower priority

Task1_10ms()
{
CAN_send1();
CAN_send2();
CAN_send3();
Motor_algo();
}

Task2_20ms()
{
Read_inp();
DCDC();
LV_check();
}

All CAN msg should be sent at 10ms.

Now this Task1 loop will be executed every 10ms and so that means when system is started :
CAN_send1() will be sent at first 10th ms
CAN_send2() will be sent at 20th ms
CAN_send3() will be sent at 30th ms
Motor_algo() at 50th ms..

Is this correct because it feels wrong and I am confused now..
