![]() But before starting let's discuss that why we should not use delay() function in any project. Arduino also has a delay() function which is used widely. Since the Arduino runs in low frequency and RAM compare to Laptop/Mobile/PC so the time given to each task will also be different. The concept will be almost same for the Arduino Multitasking, except the time distribution will be a bit different. ![]() This is how the multitasking is done in most of the systems. Let’s discuss how OS manages multitasking.Īs seen in the picture, the CPU divides the time in the three equal parts and assign each part to each task/application. The end user use all these applications at the same time but OS takes this concept a bit different. The good example of multitasking in computers are when users run the email application, internet browser, media player, games, at the same time and if users don’t want use the application it runs in the background if not closed. The MOS can be mobile or desktop PC Operating System. This kind of operating systems are known as MOS (multitasking operating system). Almost all operating systems feature multitasking. Multitasking simply means executing more than one task or program simultaneously at the same time. ![]() Before going into detail let’s start with understating Multitasking. So this article explains how we can avoid use of delay() function and replace it with millis() to perform more than one tasks simultaneously and make the Arduino a Multitasking controller. Here in this tutorial we will learn How Arduino performs Multitasking with Arduino millis function. Generally a delay() function is used in Arduino for a periodic task like LED Blinking but this delay() function halt the program for some definitive time and don’t allow other operations to perform. In embedded systems, microcontrollers can also handle Multitasking and performs two or more tasks simultaneously without halting the current instructions. It is connected to the standard clock and data pins.The multitasking has led the computers to a revolution where one or more programs can run simultaneously which increases efficiency, flexibility, adaptability and productivity. I can't imagine an I2C part causing the problem. It's not very complex, including the D1 there is an ADS1115 ADC and associated resistors/diodes to condition the input. ![]() The flakey board is mounted on a PC board that I designed, had manufactured and populated. If I press the restart button it works OK and if I remove and replace power it seems to work OK. I've also discovered that the problem only arises when the board is reset at the end of the upload. It behaves as expected, such as others have reported so I only have to believe the D1 has a problem. I happened to have another 8266 dev board with me, I discovered, so I plugged it in and ran a few tests. Signals aren't very strong and even when I can run a speed test, I get around 2 Mb/s and lots of dropouts. I think the campground WiFi is a repeater of the AT&T cell system 'cause when my hotspot stops working the campground WiFi also does. I have two hotspots, an AT&T and T-Mobile plus the campground WiFi. I'm a bit handicapped in that I'm in a motor home in PA at a campground that has less than desirable internet access.
