<p>Hi,gdoffe</p>
<p>Thank you first for the efforts solving this problem . And I tried to use the Riot-master version that you merged this "float problem" into, and i use it now. I do find that you changed the Make.include part and the pseudomodules.inc.mk which is added the float part. And i then tried the suggestion that adding USEMODULE += scanf_float in Makefile. It is built and flashed successfully, but when i run it. I still cannot see any float number. You can see the picture below.<br>

<p>And i want to show you my code for this part.<br>

<p>you can see that i defined the variable speed float type and try to print it ,but it still cannot work. Could you pls help me find the reason why?</p>
<p>Thanks so much!<br>
Best regard!<br>
