1. usleep is inaccurate on different hardware platforms, for example, usleep (2*1000). The result is sleep for 10 ms. Is it too much? The test code is as follows: #include #include int main(int argc,char **argv){ struct timeval oldTime, newTime;

1 taskdelay Taskdelay (n) delays the task calling this function by N tick (kernel clock cycle ). This task voluntarily abandons the CPU at the specified time, except that taskdelay (0) is dedicated to task scheduling (giving the CPU to other tasks

During application programming, a task usually needs to execute a specified action after a specific delay, such as waiting for peripherals to ensure data reliability, control speaker voice time and serial communication timeout and resend. This

First, prefaceFrom an application perspective, there are three types of time-related services that the kernel needs to provide:1, and system time-related services. For example, when you write a record to a database, you need to record the operation
