2 channels of DMA won't work Hello, I'm trying to use 2channels of DMA , one for PWM in timer1 and one for reading adc1 using timer3 .dma c2 should give ccr the amount from a uint string[1000](which i deleted from this code for simplifiing to be easier to read) and dma c1 for reading adc1 when timer3 update event acure but THE PROBLEM IS: dma works only either for pwm or for adc , with changing of prescale and arr of timer3 its change and work for other one if psc=719&arr=10 0 in timer3 only pwm work and if psc =11 and arr=200 only adc work , and if psc=60000 and arr=600 (wich i want this) none of the work whats the problem ??p.s. both of them work perfectly if i dont start other one with hal_start_dma #define AvarageNum 30
uint32_t adc_resualt[1*AvarageNum];
float sensor1,sensor2,sensor3,sensor4;pwm on timer1 and adc with dam and timer3 start:MX_GPIO_Init();
MX_TIM3_Init();
MX_DMA_Init();
MX_ADC1_Init();
MX_TIM1_Init();
HAL_TIM_Base_Start(&htim3);
HAL_ADC_Start_DMA(&hadc1,adc_resualt,Ava
