I have an FMR.


I play a track 


Long Press play


Choose Pitch


Up and down work fine


If I press left or right the value moves ;down or up by 2% respectively


When I release the button it reverts to the original value
 
























Thanks Dave

Atof/sscanf and sprintf are very slow - CodeWarrior for
ColdFire

 

We are using the standard C library functions (atof,
sprintf, sscanf) to
convert between character strings and doubles. When we do,
we experience
long delays of up to 30 milliseconds to do the conversion.
When we use
these functions to convert to integers we do not experience
any
significant delay. Do you know if these functions support
floating point
operations in the hardware? Are we using the correct
library? We are
trying to avoid having to write our own conversion
functions, but it is
hard to imagine that they would be any slower. 

We are linking to the following libraries: 

C++_4i_CF_FPU_MSl.a 
C_4i_CF_CFPU_MSL.a 
Cpp_4i_CF_FPU_Runtime.a

 Any body have any thoughts
