Hi all, I’ve been having this problem :

the input must have a 32 bit signed fixed-point data type with power of two slope and zero bias. the input fraction lenghts has to be between 1 and 29 (incluse).

see the screeshoot.

I have tried to change the parameter in simulink with fixed point-tool, but nothing change. i have change the input with block convert in fixed point and other solution but i have the same problem.

With this DMC block i must have a fixed point library? because i don’t have fixed point toolbox and license installed and I would like to know if there is any way around to this problem, or i have to buy it.

My system: Windows 7 64bits

Code Composer: v5.5 Matlab/Simulink: 2013b 64bits Bios: 5.42.01.09 Controller: TI TMS320F28069 code generation tool : 6.4.3 Thank you very much in advance for your help.
