Microprintf is a tiny printf implementation for embedded systems with a very small memory footprint. Microprintf uses only 256 bytes of internal static memory by default and can be configured to use even less if need be.
Tested on the following architectures:
- RISCV.
- ARM32.
- ARM64.
- X86_64.
Drop printf.c and printf.h into you project and include printf.h. Then define your custom printf handler, e.g.
void printf_handler(char c)
{
putchar(c);
}
Types:
%cCharacter.%dSigned decimal integer.%uUnsigned decimal integer.%sString of characters.%bUnsigned binary.%xUnsigned hex (lowercase).%XUnsigned hex (uppercase).%pUnsigned pointer address.
Flags:
0Zero padding-Left align+Right align.
