Internal clock and RTOS system

1.RTOS is not better, it just depends on the needs. When you have some complex applications and multi-task scheduling, it is very troublesome to control the time on a bare metal machine. At most, you can write a time slice schedule yourself. Then RTOS is better for task management. It is equivalent to a single-chip system, so it is much more convenient to use RTOS on general material network products?

2. What are the advantages and disadvantages of built-in high-speed clock and low-speed clock? In general situations, can the internal clock be used instead of the crystal oscillator?

The built-in accuracy is generally not too high

Now that RTOS systems are becoming more and more popular, you have to learn one.

It does not need to be very accurate, but it must meet the product's five-year service life. The current ADC acquisition frequency is once every 100ms, and 20 bytes are stored every second. If the flash is used as an EEPROM, how many times can it be erased and written? How many years is it converted into?

It is better to be cautious when using flash as eprom.

It depends on the requirements. If the device needs to be connected to Ethernet, it is best to run RTOS in the embedded device, otherwise the system will be unstable. The internal clock is not accurate enough.

Why can running RTOS make the clock more accurate?

I just finished reading the official FreeRTOS introductory manual and roughly understood what is going on.

The next step is to run the included routines.
