Hello everyone !

I've successfully connected stm32f4 discovery board with Matlab R2015a Simulink, but when i make a block diagram for generating simple pwm on simulink and set the sampling time of 0.1 milli seconds or less than that then a significant time delay is observed on output ports of stm board, the output is not accurate in that case...!Anyone, who've struggled and came up with a solution, help me please !I'll be highly obliged...Regards ! #stm32f4

Hi butt.usman,

For R2014b and R2015a MATLAB version, code generation for peripheral initialization is not done. This will be solved for R2015b. In this link you will find a patch to workaround the problem.
