In this cases the following implementation can be used. Absolutely **NO dependencies** are required, *printf.c* brings all necessary routines, even its own fast `ftoa` (float), `ntoa` (decimal) conversion. -If memory footprint is really a critical issue, floating point and 'long long' support and can be turned off via the `PRINTF_SUPPORT_FLOAT` and `PRINTF_SUPPORT_LONG_LONG` compiler switches. +If memory footprint is really a critical issue, floating point and 'long long' support and can be turned off via the `PRINTF_DISABLE_SUPPORT_FLOAT` and `PRINTF_DISABLE_SUPPORT_LONG_LONG` compiler switches. When using printf (instead of sprintf/snprintf) you have to provide your own `_putchar()` low level function as console/serial output. -- cgit v1.2.3
