error compilation

[ELMAY]

bonjour
je test un model .mdl pwm mais il apparait une erreur

svp est ce que vous pouvez m`aider
merci d*avance

Hi Elmay,

Unexpected problem, easily solved however !

It happens that your model name pwm.mdl generates C code files with the same name (i.e. pwm.c and pwm.h). But the model must include another files which is pwm.h from the microchip library. Here, the generated file pwm.h shadows the microchip library file pwm.h.

Workaround:
Rename your simulink file into pwm_test.mdl for example. Compilation is then Ok.

Others ticks : a model time step of 1/100000 which is 1us is pretty fast for the microcontroller ! You should try with a 1ms or 250us time step for example ! This time step has no effects on the max PWM frequency you can achieved.

I am also not certain that PWM blocks is configured as you expected it.
Here, the period id set to (1000/PWM*0.41943) with PWM = 65534 thus you'll get a period of 6.4ms and duty cycle (500/1000 = 50%) of 3.2ms.

Please try to copy/past from the matlab workspace the errors you obtain using the forum Code function. Try to add to the model you posted a screenshot of it. It may help other users and I may respond faster.

Hello,

I make changes on this model but still error appears
thank you

Could you test with the model I uploaded on the forum ?
