Why are 32 bits timers longer to be set up with pwm mode using DMA burst feature? (F446RE) Hi, I am using this code, TIM1,3,4,8 are working directly like a charm, but TIM2 and TIM5 the only 32 bits timers are taking approximately 1 minute and 45 seconds to be working. Does anyone know where comes this issue? uint16_t buffer1[12] = {0,35,0, 18,2, 56,0,15,2,45,0,12};
uint32_t buffer2[12] = {0,180000000,0, 90000000,2, 56,0,15,2,45,0,12};
uint16_t buffer3[12] = {0,35,0, 18,2, 56,0,15,2,45,0,12};
uint16_t buffer4[12] = {0,35,0, 18,2, 56,0,15,2,45,0,12};
uint32_t buffer5[12] = {0,35,0, 18,2, 56,0,15,2,45,0,12};
uint16_t buffer8[12] = {0,35,0, 18,2, 56,0,15,2,45,0,12};
