how to code microprocessors and microcontrollers in python or do I need to learn assembly

the_future

Hi everyone i just wanted to know if learning assembly is really

needed and how to code other microcontrollers and microprocessors

like arduino and raspberry pi but are not arduino and raspberry pi or

in case I wanted to design my own circuit board

    I completely agree with John,

    Michael I think you misunderstood

    Assembly is always faster than c,  even in avr

    Binary is even faster

    It is because even in a language like there is a lot of code that is not necessary for the program to function(libraries) ,

    In a computer with 16GB ram and 3.6ghz processor it is not a problem but when used with a mcu with 8kb ram and 16mhz processor it has effects on speed of execution.

    @s142857, there's a not bad Wiki article about assembler which will help you to understand why assembler and binary run at the same speed.

    Assembly language - Wikipedia, the free encyclopedia

     

    Assembler (in real life) isn't always faster than C because it takes too long to write it well. In the days when there was no choice most programmers used libraries of code which meant that they were using  a standard bit of code for most jobs rather than opitimising exactly for each tiny task - which is pretty much what compilers do except they don't get bored and make silly mistakes so easily.

     

    C compilers and linkers generally do a good job of not including code which isn't used  - a lot of my C code is running on processors with less than 8k of RAM. Speed and code size are not always directly related - for example it may be faster on some processors to unroll a loop and repeat the same code many times  - leaving chunks of unused code in a programme is bad practice but it doesn't necessarily make it slower.
