I am trying to get both PWM CH1 and PWM CH2 to fire independently with TIM15.
However, both are enabled at the same time.
Using CubeMX to generate initialization function:
void MX_TIM15_Init(void)
{
/* USER CODE BEGIN TIM15_Init 0 */
/* USER CODE END TIM15_Init 0 */
TIM_MasterConfigTypeDef sMasterConfig = {0};
TIM_OC_InitTypeDef sConfigOC = {0};
TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig = {0};
/* USER CODE BEGIN TIM15_Init 1 */
/* USER CODE END TIM15_Init 1 */
htim15.Instance = TIM15;
htim15.Init.Prescaler = 3200-1;
htim15.Init.CounterMode = TIM_COUNTERMODE_UP;
htim15.Init.Period = 1500-1;
htim15.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
htim15.Init.RepetitionCounter = 0;
htim15.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;
if (HAL_TIM_PWM_Init(&htim15) != HAL_OK)
{
Error_Handler();
}
if (HAL_TIM_OnePulse_Init(&htim15, TIM_OPMODE_SINGLE) != HAL_OK)
{
Error_Handler();
}
sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
if (HAL_TIMEx_MasterConfigSynchronization(&htim15, &sMasterConfig) != HAL_OK)
{
Error_Handler();
}
sConfigOC.OCMode = TIM_OCMODE_PWM2;
sConfigOC.Pulse = 1;
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(&htim15, &sConfigOC, TIM_CHANNEL_1) != HAL_OK)
{
Error_Handler();
}
__HAL_TIM_DISABLE_OCxPRELOAD(&htim15, TIM_CHANNEL_1);
if (HAL_TIM_PWM_ConfigChannel(&htim15, &sConfigOC, TIM_CHANNEL_2) != HAL_OK)
{
Error_Handler();
}
__HAL_TIM_DISABLE_OCxPRELOAD(&htim15, TIM_CHANNEL_2);
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(&htim15, &sBreakDeadTimeConfig) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN TIM15_Init 2 */
/* USER CODE END TIM15_Init 2 */
HAL_TIM_MspPostInit(&htim15);
}
Then just doing this to start and test things:
// OutputChannel isn't even used in the code //
if (HAL_TIM_OnePulse_Start(&htim15, TIM_CHANNEL_1) != HAL_OK) {
serprintf("Issue with interrupt on TIM51 channel");
Error_Handler();
}
Finally, enablement of the timer:
This actually enables both CH1 and CH2 at the same time.
TIM15->CR1 = TIM_CR1_CEN|TIM_CR1_OPM;
Can I accomplish this with both channels independently?
