How do you write a 4-button program in 51 assembly to perform different operations in different interfaces? I started by writing a scan pin JB statement after each interface, but this wastes program s...
The Tiny Lisp Computer 2 (uLisp microcomputer) is a small standalone device based on the ATmega1284 that has its own display and keyboard and can be used to program in uLisp. For more information, see...
As the title says [code]/*practise 8.2*/ /*This program is very simple, just convert the input integer into character type output*/ #include char *itoa(int n,char str[]) //God knows why I came up with...
I used IAR 9.3 to write a small positioning program for broadcast transmission and reception. I did not use the protocol stack. Every time I debugged it in a single step, the length value was too larg...
