DMA trigger by TIM1 Conifguration -PWM generation not getting correct PWM
I am generating PWM signals for 4 channels using TIM1, with 2 complimentary outputs. The CCR values should come from an array lookup table via DMA.
is this means The DMA trigger by TM1 ?
I am trying to generate a sinewave from the following array
uint16_t sin_table[160]={0, 5, 10, 15, 20, 25, 29, 34, 39, 44, 49, 54, 58, 63, 68,
73, 77, 82, 87, 91, 96, 100, 105, 109, 113, 118, 122, 126, 131, 135, 139,
143, 147, 151, 155, 159, 162, 166, 170, 173, 177, 180, 184, 187, 190, 193,
196, 199, 202, 205, 208, 211, 213, 216, 218, 220, 223, 225, 227, 229, 231,
233, 235, 236, 238, 239, 241, 242, 243, 244, 245, 246, 247, 248, 248, 249,
249, 250, 250, 250, 250, 250, 250, 250, 249, 249, 248, 248, 247, 246, 245,
244, 243, 242, 241, 239, 238, 236, 235, 233, 231, 229, 227, 225, 223, 220,
218, 216, 213, 211, 208, 205, 202, 199, 196, 193, 190, 187, 184, 180, 177,
173, 170, 166, 162, 159, 155, 151, 147, 143, 139, 135, 131, 126, 122, 118,
113, 109, 105, 100, 96, 91, 87, 82, 77, 73, 68, 63, 58, 54, 49, 44, 39, 34, 29, 25, 20, 15, 10, 5};
HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table, 160);
HAL_TIMEx_PWMN_Start_IT(&htim1, TIM_CHANNEL_1);
HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_2, (uint32_t *)sin_table, 160);
HAL_TIMEx_PWMN_Start_IT(&htim1, TIM_CHANNEL_2);
I am not getting the 160 values as per the array value
FPWM is 16KHZ
What wrong with me ?
please help me
