- The hex file size generated by Arduino IDE is also a problem. A source code that just blink a LED, once compiled, generates a hex file greater than 1 Kbyte. Same code in Bascom is below 250 bytes and in IAR below 100 bytes.
Apples and oranges. Is your Bascom 'same code' initiating and controlling a timer to support a millis() and microSecond() freerunning timer?
Basic was a good way to learn getting started with programming, but soon there is a need to grow up, join the real world and work for a living.
