Hallo to all,

I plan to move to STM32 and now I am working on System Workbench + HAL + Cube MX. All works fine. My Problem: Where I can find information and/ or didactically well prepared tutorials, how to use the STM32?
Example:
Wenn you plan to use an GPIO Pin, then you have to configure the pin first, that is what I expected. In HAL Semantics it would be written like

int main(void)
{
HAL_Init();
MX_GPIO_Init();
}
where MX_GPIO_Init() is
static void MX_GPIO_Init(void)
{

GPIO_InitTypeDef GPIO_InitStruct;

/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOC_CLK_ENABLE();
__HAL_RCC_GPIOH_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
__HAL_RCC_GPIOB_CLK_ENABLE();

/*Configure GPIO pin Output Level */
HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);

/*Configure GPIO pin : B1_Pin */
GPIO_InitStruct.Pin = B1_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(B1_GPIO_Port, &GPIO_InitStruct);

/*Configure GPIO pin : LD2_Pin */
GPIO_InitStruct.Pin = LD2_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(LD2_GPIO_Port, &GPIO_InitStruct);

}

Cube MX delivered the code.

How can I know, that I have surprisingly to enable someting_like_ CLK or somthing_like_SPEED in order to use a pin? And what, when I try to use different Timers, ADC, FPU?
Main Question:
Is there a documenation which explaines the usage of the STM32, that means how to use GPIO, Timers, ADC, FPU with Code Examples (for HAL), like a cook book? Maybe there is, i cant find in the Internet. How you did your first practice?

Thanks in advance for constructive answers
