the printf float support with -Wl,-u,vfprintf -lprintf_flt is somehow unconditional. it makes even Blink large

| Jun 8, 2020 at 14:02 | comment | added | Edgar Bonet | I compiled both versions for the Uno with float support and, to my surprise, Juraj's is smaller (text: 4814, data: 68, bss: 166) than yours (text: 6226, data: 62, bss: 166). | |
| Jun 8, 2020 at 12:02 | comment | added | Majenko | @Juraj Maybe on the Arduino, but then the Arduno printf lacks float support, which is included in the code here. If you take out the float support you will most likely find this code considerably smaller. Float support is massive. | |
| Jun 8, 2020 at 12:00 | comment | added | Juraj♦ | sorry. no. printf produces a little smaller code. I use my StreamLib for printf wrapper for Serial github.com/jandrassy/StreamLib/blob/… | |
| Jun 8, 2020 at 11:49 | comment | added | Majenko | @Juraj A lot. Take a look at the link in my comment above for a "light weight" printf formatter and you'll see how much is involved in it. | |
| Jun 8, 2020 at 11:48 | comment | added | Juraj♦ | how much flash space does this save compared to printf? in my test none. | |
