TIM6 setting in stm32cubemx

Dear All,

I am working in STM32F070R8T6.

For the Timer base pwm generation I need to use TIM6, I have no option for choosing TIM1 and TIM2.

I need to activate internal pwm which may cause by pressing GPIO key button.

Kindly, help me to set TIM6 in stmcubemx.

Hi hasan.md_mubdiul,

''I am working in STM32F070R8T6.

I guess that you use STM32F070RBT6 (not STM32F070R8T6), and you don?t have option for choosing TIM1 and TIM3 (not TIM1/2)

TIM6/7 are basic timers witch don?t feature independent channel for PWM generation so you cannot use them.

As shown in this figure you can use TIM14/15/16/17

Dear Sir Syrine,

Thank you very much, I saw this in datasheet that TIM6/7 will not be use for this MCU.

My circuit does not contain any external TIMER I/O port. That means, I have to activate internal timer.

This setting generates,

static void MX_TIM14_Init(void)

{

TIM_IC_InitTypeDef sConfigIC;

htim14.Instance = TIM14;

htim14.Init.Prescaler = 0;

htim14.Init.CounterMode = TIM_COUNTERMODE_UP;

htim14.Init.Period = 0;

htim14.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;

if (HAL_TIM_Base_Init(&htim14) != HAL_OK)

{

Error_Handler();

}

if (HAL_TIM_IC_Init(&htim14) != HAL_OK)

{

Error_Handler();

}

if (HAL_TIM_OnePulse_Init(&htim14, TIM_OPMODE_SINGLE) != HAL_OK)

{

Error_Handler();

}

sConfigIC.ICPolarity = TIM_INPUTCHANNELPOLARITY_RISING;

sConfigIC.ICSelection = TIM_ICSELECTION_DIRECTTI;

sConfigIC.ICPrescaler = TIM_ICPSC_DIV1;

sConfigIC.ICFilter = 0;

if (HAL_TIM_IC_ConfigChannel(&htim14, &sConfigIC, TIM_CHANNEL_1) != HAL_OK)

{

Error_Handler();

}

if (HAL_TIMEx_RemapConfig(&htim14, TIM_TIM14_MCO) != HAL_OK)

{

Error_Handler();

}

My aim is to apply this timer along with pwm and use it by press key.

Kindly, refer me any helpful example source code.

Regards

Hasan
