I would like to take a somewhat different look at your "problem". Code that is transferable between CPUs without modification: it's one of those things that makes the 21st century so superior to the last century, where all the other developers are still living. The profundity of those last two words is usually missed by beginners in the field of embedded-systems development, but they strike awe in the people who have mastered many similar-in-concept-but-different-in-a-thousand-details microcontrollers over the years. But your final application code is transferable to other Arduino-supported AVR devices and even a few ARM devices, without modification. It takes the same amount of time to learn how to do microprocessor development in Arduino C++ as it does for standard C or assembler. These libraries have callback functions that handle the activity that is triggered by a button action. Then the current button status (such as pressed, released, held for x milliseconds) is compared to status recorded on the previous time that the button was sampled. Both of these libraries sample the button's status at user-programmable intervals. With this standard platform, you would handle buttons by using one of the two popular Arduino button libraries on GitHub. I just typed that in from memory, so don't freak if there's one letter wrong or worse.Īllow me to go against everyone else's advice and recommend that you not deal with any AVR except the mega328p because that AVR device is the one that is found on the international AVR standard hardware development platform: The Arduino UNO and Nano boards. I assume you want it to change state when you push the button, rather than when you release it. What you want is a 'software toggle' or 'push on push off' button. Should be longer than bounce duration, several ms If(swtoggleon) setledson() else setledsoff() If(swpushedfallingedge) swtoggleon = !swtoggleon //flip state on falling edge Swpushedlast = swpushed //remember state for next pass Swpushedfallingedge = swpushed & !swpushedlast //edge detect Swpushed = SWPUSHED() //read switch state right now Unsigned char swtoggleon //the software toggle that is the message subject Unsigned char swpushedlast //saves current state for next pass Unsigned char swpushedfallingedge //one shot of switch being pushed Unsigned char swpushed //saves the current state #define SWPUSHED() (PORTB & 1)=0 //reads the input I really don`t have idea where is mistake, as I`m still very nooby. Sometimes when I push button LED not switch to opposite state (or switch 2 times too fast? I dunno) and if i keep button pressed LED is blinking. I wrote the same in C and here is some problem. Without considering debounce.Īt first I wrote code in assembly and tested it in Proteus. With TPM v2.0 on board, UP Squared V2 has added hardware-based, security-related functions as well.ĪAEON is taking pre-orders for the UP Square 2 starting at $161 for the model with a Celeron N6210, 2GB RAM, 32GB eMMC flash, and going up to $323 with a Pentium J6426 CPU, 64GB eMMC flash, and 16GB RAM.One of the simpliest project everyone ever seen: Turning on and turning off LED using one button. It also designed with M.2 slots to unlock WiFi/ Bluetooth/ AI/ Storage expansion capability. UP Squared V2 with the Intel® Pentium® Processor J6426 and Intel® Celeron® Processor N6210 (formerly Elkhart Lake)Įxpand your UP Squared V2 further with the 40 GPIO having the same connector and pin definition of UP series boards, giving developers freedom to build up their shield.UP Squared V2 offers high performance with low power consumption in a form factor that can fit anywhere. It has been upgraded to 12V standard industrial power input, increased memory options and audio wafer for easily expand the audio mic-in and line out feature. Based on the latest Intel® Pentium®, and Intel® Celeron® N and J Series processors (formerly Elkhart Lake), UP Squared V2 offers up to 1.7x better compute performance and twice the performance for 3D graphics with Intel® UHD Graphics for 10th Gen Intel® Processors. UP Squared V2 is the successor to our UP Squared series.
