Hello everyone, I had a question about how to run IRTIM on STM32F030. If there is an answer please tell me how to solve it?

What exactly is not clear in chapter 18  Infrared interface (IRTIM) of RM0360? There's even a code example in the appendix.

But they run PB9 and not PA13 (IR_OUT).

Could you please reset the sample code using PA13 (IR_OUT).Thanks!

Another minute of your attention. How to start PWM - TIM16 and TIM17 correctly? I set up IRTIM in CubeMX and set TIM16 to 'Output compare no byout' and TIM17 to 'PWM Generation no output' but it did not work.

Here is part of my code:

static void MX_TIM16_Init(void)

{

TIM_OC_InitTypeDef sConfigOC;

TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig;

htim16.Instance = TIM16;

htim16.Init.Prescaler = 9; htim16.Init.CounterMode = TIM_COUNTERMODE_UP; htim16.Init.Period = 240; htim16.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim16.Init.RepetitionCounter = 0; htim16.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim16) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

if (HAL_TIM_OC_Init(&htim16) != HAL_OK)

{ _Error_Handler(__FILE__, __LINE__); }

sConfigOC.OCMode = TIM_OCMODE_TIMING;

sConfigOC.Pulse = 0; sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH; sConfigOC.OCNPolarity = TIM_OCNPOLARITY_HIGH; sConfigOC.OCFastMode = TIM_OCFAST_DISABLE; sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET; sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET; if (HAL_TIM_OC_ConfigChannel(&htim16, &sConfigOC, TIM_CHANNEL_1) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

sBreakDeadTimeConfig.OffStateRunMode = TIM_OSSR_DISABLE;

sBreakDeadTimeConfig.OffStateIDLEMode = TIM_OSSI_DISABLE; sBreakDeadTimeConfig.LockLevel = TIM_LOCKLEVEL_OFF; sBreakDeadTimeConfig.DeadTime = 0; sBreakDeadTimeConfig.BreakState = TIM_BREAK_DISABLE; sBreakDeadTimeConfig.BreakPolarity = TIM_BREAKPOLARITY_HIGH; sBreakDeadTimeConfig.AutomaticOutput = TIM_AUTOMATICOUTPUT_DISABLE; if (HAL_TIMEx_ConfigBreakDeadTime(&htim16, &sBreakDeadTimeConfig) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

}

/* TIM17 init function */

static void MX_TIM17_Init(void){

TIM_OC_InitTypeDef sConfigOC;

TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig;

htim17.Instance = TIM17;

htim17.Init.Prescaler = 0; htim17.Init.CounterMode = TIM_COUNTERMODE_UP; htim17.Init.Period = 1263; htim17.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim17.Init.RepetitionCounter = 0; htim17.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim17) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

if (HAL_TIM_PWM_Init(&htim17) != HAL_OK)

{ _Error_Handler(__FILE__, __LINE__); }

sConfigOC.OCMode = TIM_OCMODE_PWM1;

sConfigOC.Pulse = 40; sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH; sConfigOC.OCNPolarity = TIM_OCNPOLARITY_HIGH; sConfigOC.OCFastMode = TIM_OCFAST_DISABLE; sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET; sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET; if (HAL_TIM_PWM_ConfigChannel(&htim17, &sConfigOC, TIM_CHANNEL_1) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

sBreakDeadTimeConfig.OffStateRunMode = TIM_OSSR_DISABLE;

sBreakDeadTimeConfig.OffStateIDLEMode = TIM_OSSI_DISABLE; sBreakDeadTimeConfig.LockLevel = TIM_LOCKLEVEL_OFF; sBreakDeadTimeConfig.DeadTime = 0; sBreakDeadTimeConfig.BreakState = TIM_BREAK_DISABLE; sBreakDeadTimeConfig.BreakPolarity = TIM_BREAKPOLARITY_HIGH; sBreakDeadTimeConfig.AutomaticOutput = TIM_AUTOMATICOUTPUT_DISABLE; if (HAL_TIMEx_ConfigBreakDeadTime(&htim17, &sBreakDeadTimeConfig) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

}

Modulation on the PA13 leg does not start.

Ok, but isn't that just a matter of pin configuration and AF mux setting, ie PA13 (AF1) vs PB9 (AF0), as either can be routed to IR_OUT

Yes. I use st-link v2. And that it off and delete?

 ,

 ,

Change the GPIO configuration, along the these lines

 , GPIO_InitStruct.Mode , , , , , = GPIO_MODE_AF_PP,

 ,

 , GPIO_InitStruct.Pull , , , , , = GPIO_NOPULL,

 ,

 , GPIO_InitStruct.Speed , , , , = GPIO_SPEED_FREQ_HIGH,

♯ if 1

 ,

 , __HAL_RCC_GPIOA_CLK_ENABLE(), // PA13 AF1

 ,

 , GPIO_InitStruct.Pin , , , , , , = GPIO_PIN_13,

 ,

 , GPIO_InitStruct.Alternate = GPIO_AF1_IR,

 , HAL_GPIO_Init(GPIOA, &,GPIO_InitStruct),

 ,

♯ else

 ,

 , __HAL_RCC_GPIOB_CLK_ENABLE(), // PB9 AF0

 ,

 , GPIO_InitStruct.Pin , , , , , , = GPIO_PIN_9,

 ,

 , GPIO_InitStruct.Alternate = GPIO_AF0_IR,

 , HAL_GPIO_Init(GPIOB, &,GPIO_InitStruct),

 ,

♯ endif
