as explained, ISRs should run as fast as possible and should not perform long operations, such as writing to the serial port. Thus, a good way of implementing interrupt handling code is making the ISR only signal the occurrence of the interrupt and defere the actual handling (which may...
To prevent this from happening I might need to set the brownout voltage to be 1.8V and this can be done as explained in this comment. Battery Level Detector As previously said we will build a potential divider to measure the battery voltage. The input from the potential divider will go ...
The Rules code consists of two files Rules.h and Rules_prog.h. The former is the library functionality for the Rules. The other file is where you enter your HEX codes from the spreadsheet as well as setting up your Flags, commands and timers. These files generate serial messages that give...

In chapter 1 you will learn how to set up the programming environment for Arduino and start programming the Arduino UNO board.
Porting arduino libraries to libmraa as UPM libraries is usually fairly easy. The issues typically come from misunderstanding of how a non real time OS deals with interrupts and timers. It also highly depends on the sensor. A concrete example is explained in detail onMaking a UPM module for ...
While the ESP32 is in deep sleep mode, the RTC memory also remains powered on, so we can write a program for the ULP co-processor and store it in the RTC memory to access peripheral devices, internal timers, and internal sensors. ...
The timers can be made available withstopMozzi(), which stops audio interrupts, until you callstartMozzi(). Note that it is of utmost importance to write non-blocking code, such that the audio buffer never runs low. Hints on how to do this, including why, and how you should avoid using...
Now i have it finally running and i´m using your sketch to switch a LEd on and off just like it´s explained here. But what happens is that when i upload the sketch the LED goes on…when it reaches the Time for “MorningAlarm it goes off…when it reaches the time for the “...
Keep in mind that to generate the PWM signals the Servo Library will need to use some of the internal Arduino timers, specifically Timer 1. This can interfere with other libraries that also need the same timers. One way around this is to look for alternate libraries for either the servo of...
