Ports 20 and 21 do not (I don't understand why, at the moment). I think it may be something to do with this part, But I don't really Jun 27, 2018 · Multi threading does not require multiple processors or cores! Multi processing does not require multiple processors or cores! All it means is saving where we are upto in one job/task and then moving on to some other task. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Of course, you could achieve the same things using a stock Arduino with some crafty coding or timer interrupts, however using a purpose-built language such as this could be a great way to get your feet wet in threaded computing Jul 14, 2022 · Hello My project consists of Arduino mega 2650 Esp32 Ethernet module (w5500) Esp32 will be responsible for receiving 30 feedback (using shift register) . Display and update messages on the Arduino without delays. Ports 18 and 19 work correctly, waking up Arduino Mega 2560 with RAISING, LOW, HIGH, CHANGE and FALLING parameters. Another option is a Direct Memory Address controller which gives you the opportunity to (nearly) run several process at a time with a single core because a DMA requires very few CPU load, and you can even run several DMA process at a time.
