STM32-MAT Matlab target. Problem with GPIO

Posted on November 05, 2015 at 08:17

I am now trying to make stm32 matlab target work with stm32 discovery f3 board.

The problem i have is when i am using GPIO_write block in simulink it updates GPIO only once on reset.

C code line

HAL_GPIO_WritePin(GPIOE, GPIO_PIN_13, SimpleGPIO_B.DataTypeConversion);

is present only in initialize procedure and does not appear in step().

If i copy this line to step() everything works fine.

Input signal for GPIO_Write block is not constant, i can see it changes if i use debugger.

Also in simulink itself GPIO_Write block is marked as constant.

It looks like code generator considers this block constant and does not update in inside step() despite it has variable input.

Is there a proper way to fix this without changing generated code each time?
