I wander what is the best option for formatting strings in Arduino for output. I mean what's a preferable way in the point of view of performance, memory usage – things like that. I see, people usually use direct Serial.print/println, like this: int x = 5; // 1st option Serial.print("x = "); Serial.println(x); Or like this:

Dec 5, 2024 · arduino/arduino-ide#2571, arduino/arduino-cli#2707, arduino/arduino-cli#2665, arduino/pluggable-discovery-protocol-handler#50. Previously, Arduino IDE would sometimes hang on startup if the user had previously installed @earlephilhower's excellent "Raspberry Pi Pico/RP2040" boards platform. Compatibility with that platform has now been restored.

Jan 28, 2022 · Some ESP-family cheap boards manufacturers had recently moved to CH9102X serial port chip (from CP2102), and it seems the drivers for CH9102X are hard to find.

Making embedded systems accessible to all. Discussion about software tools used for development and deployment of Arduino projects.

Open the arduino IDE and click on File\Preferences and tick the option ;'Show verbose output during: 'upload'.Then close the 'Preferences' screen. Load a small program that works. e.g. File\Examples\01.Blink. In the for your arduino board setup in the Arduino IDE; Tools\Board ... such as Arduino Nano. Tools\Processor ... such as ATmega328P

Jun 3, 2014 · For most Arduino boards, hardware multithreading isn't supported. However, there are ways to implement software multithreading . The approach by AsheeshR wouldn't work well for functions that take a long time to complete (i.e. something in a library that takes a while, or a delay) because it would get jammed up by those instructions, but it ...

Dec 2, 2010 · With my BASIC language programmed controllers I can use AND and OR. example: IF (VAL > 100 AND VAL < 140) THEN ... How can I solve this with the if function in the Arduino? Thanks. 😉

Jul 17, 2014 · Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

Sep 18, 2019 · You will see there are 4 data lines for parallel operation (Dat0, Dat1, Dat2, and CD/Dat3), and the Clock and Command (CMD) pin. Arduino uses serial operation over the SPI bus tho, so in this case CD is likely card detect from what appears to be a mechanical lever switch at the bottom of the socket.

Sep 26, 2014 · Following the KISS principle, I have recently published the Instructable "Simple Multi-tasking in Arduino on any board" It covers non-blocking delays, non-blocking serial output, non-blocking user input, removing delays from third party libraries, and loop timers, so you can see and adjust the response/latency of your tasks.
