Is it better to use #define or const int for constants?

WebProgramming an ESP-12E / ESP-12F / NodeMCU over Wi-Fi is a Catch-22. You need to run an Arduino sketch capable of receiving code updates over Wi-Fi to upload your code over Wi-Fi. You can get around that by getting the USB connection working first. You can then upload a sketch running the "ArduinoOTA" library to upload code over Wi-Fi. WebPROGMEM is a Arduino AVR feature that has been ported to ESP8266 to ensure compatibility with existing Arduino libraries, as well as, saving RAM. On the esp8266 declaring a string such as const char * xyz = "this is a string" will place this string in RAM, not flash. It is possible to place a String into flash, and then load it into RAM when it ... WebMar 1, 2014 · Indeed, a lot of Arduino code is very C like though. C has traditionally used #define s for constants. There are a number of reasons for this: You can't set array sizes using const int. You can't use const int as case statement labels (though this does work in some compilers) You can't initialize a const with another const. mix match socks for girls
