Dear friends,

I'll be using stm32f4 discovery with Matlab embedded coder. Now I'm not quite sure if this is the right place to ask for Matlab help,but my queries are solely related to the hardware programming.

Now my objective is simple. I want my board adc to trigger when some external high to low pulse occurs on a gpio pin. Only thing I want to do this task on simulink. I could initialise the ADCs GPIOs, but the connection for the external trigger seems to be tricky. Yes I'm not much conversant with the embedded coder, looking forward for some help in this regard.

Thanks & regards,

Souvik

Hi Souvik,

sorry for the late answer.

I think that you can use GPIOs external interrupt to do that.

You can have a look to .../Test/ButtonAndLeds_Interrupt model example.

IRQ_Ext trig ADC_read instead of GPIO_Write.

Best regards

Pascal
