Interrupts in Arduino Due
-
I require my Arduino Due to be able to plot a square wave with a predetermined duty cycle and time period, without the use of delay() or millis() or any such function that keeps the processor idle unnecessarily. Hence, I've decided to go for interrupts and found a lot of resources on implementing it on the Uno, but none for the Due.
Can someone shed light on how I can set up an interrupt ( I guess two will be required here) from the inbuilt timers in the Due?

Hi @SuperGops , All the digital pins of Arduino Due are capable of interrupts, and since you are using the Arduino framework everything is the same as Arduino Uno.

@salmanfaris Thanks! I'll definitely have a look at these!
-
@SuperGops You can use a Timer interrupts or run interrupts via watchdog timer.

@SuperGops When you want to create a PWM signal, why don't you just use
analogWrite(dutycycle)to just create your PWM? Is there any specific reason you are going for interrupts?

In this second edition of MakerCuriosity Podcast Series by MakerGram, we are discussing programming Microcontrollers using Python.
The discussion includes how exactly an interpreted language works on a Microcontroller?! Besides that, we have covered the pros and cons and when it is preferred to use Python on Microcontrollers when 95% of existing embedded code is written using either C or C++. Listen now and let us know your feedback and opinion!
Stay tuned till we meet with another exciting topic on next week!

Hi all,
I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.
Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows. -

@abdultechguy999 usually https://dl.espressif.com/dl/package_esp32_index.json this works while installing through boards manager. But I faced the same issue some times. it might be due to a couple of reasons.
Bad Internet connectivity
The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)
I remember there is a way to install the board files offline by downloading from some github repos.
All the best.

Ok, then you need to check the LM2596 output current and voltage!
