Simple usage and Exception Handling of parallel programming, and Exception Handling of parallel usage
When a large amount of data needs to be processed or a large number of tasks need to be completed, and each data or task is independent of each other, parallel programming can be considered. Modern computers are multi-core, and parallel programming can improve CPU utilization to increase throughput.
The Parallel. Invoke parameter can receive an array of actions.

I have to say that STMicroelectronics is really a bit of a flirt! Even a bit of a pervert. I am not flattered by the level of editing of the ST document stm32f10xxx reference Manual. Many of the manuals are vague, and even a lot of important to the beginner of the place is a stroke, let a person really can not touch the head. Like I said earlier about the introduction of NVIC nested vector interrupt Controller, this Part I think is very important, but when you read his part of the introduction,
First, what is the Air quality indexAir Quality index (air quality index, or AQI) is a numerical value used to quantitatively describe the level of air quality. The AQI value range is located between 0–500.There are many types of ambient air pollutants, such as sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3) and suspended particulate matter. In suspended particulate matter, the diameter is less than or equal to 10μm called PM10, and the diameter is less than or equ
