STM32CubeMX GPIO Defined initial level after initialization

To avoid

glitches

at the output

,

we

initialize

in

the following order

:

1. GPIOx

clock

enable

2. Set output

registers

to

defined value

3. Perform

initialization

Now we would

like to use

STM32CubeMX

.

Is it

possible

when initializing the

GPIO

to initialize the

output level

?

Example of

implementation:

In source:   /*Configure GPIO pins : PE2 PE3 PE4 PE5                            PE6 PE8 PE9 PE10                            PE11 PE12 PE14 PE15                            PE0 PE1 */   HAL_GPIO_WritePin(GPIOE,GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_4|GPIO_PIN_5                           |GPIO_PIN_6|GPIO_PIN_8,GPIO_PIN_RESET);   HAL_GPIO_WritePin(GPIOE,GPIO_PIN_8|GPIO_PIN_9|GPIO_PIN_10                           |GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_14|GPIO_PIN_15                           |GPIO_PIN_0|GPIO_PIN_1,GPIO_PIN_SET);   GPIO_InitStruct.Pin = GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_4|GPIO_PIN_5                           |GPIO_PIN_6|GPIO_PIN_8|GPIO_PIN_9|GPIO_PIN_10                           |GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_14|GPIO_PIN_15                           |GPIO_PIN_0|GPIO_PIN_1;   GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;   GPIO_InitStruct.Pull = GPIO_NOPULL;   GPIO_InitStruct.Speed = GPIO_SPEED_LOW;   HAL_GPIO_Init(GPIOE, &GPIO_InitStruct); #initializing #stm32cubemx #gpio

Hello,

STM32CubeMX manages the GPIO initialization settings only. The GPIO level is not part of the GPIO init structure (from HAL GPIO driver). The following need to be used to set the GPIO level: /**   * @brief  GPIO Bit SET and Bit RESET enumeration   */ typedef enum {   GPIO_PIN_RESET = 0,   GPIO_PIN_SET }GPIO_PinState; #define IS_GPIO_PIN_ACTION(ACTION) (((ACTION) == GPIO_PIN_RESET) || ((ACTION) == GPIO_PIN_SET)) I have logged a ticket for your request (on STM32CubeMX and requesting the possibility to go beyond the basic GPIO initialization). Best Regards

Dear user,

Please note your request is now implemented in STM32CubeMX 4.13. Thank you
