Not arm are united, in what languages ​​of other MK?

Question

Microcontrollers

This is such a stupid question. From avr, peak, arm infa is quite transparent. What about other microcontrollers? Here, you open the lid, and there - some kind of MK from Samsung in the monitor, or some kind of STI chip in the receiver. What are they programmed with? What languages? Or is it written each time individually in the datasheet? And not all microns, in principle, can be altered?

Answer 1

1. There is such a thing as LLVM. Here is a list of his frontends (programming languages). Here is a list of his backends (target platforms).
   
2. There is such a thing as GCC (the original decoding of this abbreviation does not reflect the whole essence of this toolkit for a long time). Here is a list of its frontends (programming languages). Here is a list ( more from Wikipedia) of its backends (target platforms).
   
3. You are wrong about there being no cross-platform BASIC compiler (from comments on another answer). Thanks to LLVM it is possible and already implemented .
   

Answer 2

Everywhere C and ASM.
By the way, the language does not depend on the hardware used, here is the question of the compiler.
