sprinf conversion of float is not working for STM32F7
Hello Breinholm,
Check your linker flags (project properties > C/C++ Build > Setings > Tool Settings (TAB) > MCU GCC Linker > Miscellaneous > Linker flags),
if you are using nanolib “-specs=nano.specs” you need to add “-u _printf_float” to enable float printf.
