Thanks for the answer. But there is a lot of excess and used DMA. (STM32Cube_FW_F4_V1.6.0\Projects\STM32F4-Discovery\Examples\DAC )
I need a
simple example
generated
in
STM32Cube
triangle
generation
.
void MX_DAC_Init(void)
{
DAC_ChannelConfTypeDef sConfig;
/**DAC Initialization
*/
hdac.Instance = DAC;
HAL_DAC_Init(&hdac);
/**DAC channel OUT1 config
*/
sConfig.DAC_Trigger = DAC_TRIGGER_T6_TRGO;
sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
HAL_DAC_ConfigChannel(&hdac, &sConfig, DAC_CHANNEL_1);
/**Configure Triangle wave generation on DAC OUT1
*/
HAL_DACEx_TriangleWaveGenerate(&hdac, DAC_CHANNEL_1, DAC_TRIANGLEAMPLITUDE_4095);
HAL_DAC_Start(&hdac,DAC_CHANNEL_1);
}
/* TIM6 init function */
void MX_TIM6_Init(void)
{
TIM_MasterConfigTypeDef sMasterConfig;
htim6.Instance = TIM6;
htim6.Init.Prescaler = 0;
htim6.Init.CounterMode = TIM_COUNTERMODE_UP;
htim6.Init.Period = 500;
HAL_TIM_Base_Init(&htim6);
sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE;
sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
HAL_TIMEx_MasterConfigSynchronization(&htim6, &sMasterConfig);
HAL_TIM_Base_Start(&htim6);
}
why does not work
my code
?
Generation there but it's not a triangle!!!
