Hi everyone ! I have a problem . I started a triple mode ADC and I wanna send ADC data via usb (CDC) FS .
But my problem is , when my input length of HAL_ADCEx_MultiModeStart_DMA() is more than 256 , my sent_bytes[] numbers won,t be correct . but for numbers below 256 , sent_bytes[] are correctly added by 10 ; Please help me to send my Triple ADC data via USB .
/* USER CODE BEGIN PV */
uint16_t adc_data[512];
uint8_t sent_bytes[1408];
extern uint8_t sendFlag ;
uint8_t first_time_start = 1 ;
/* USER CODE END PV */

/* USER CODE BEGIN PFP */
extern void Send_Via_USB(uint8_t* Buf, uint32_t Len) ;

if (htim->Instance == TIM1) {
HAL_IncTick();
}
/* USER CODE BEGIN Callback 1 */
if(htim ->Instance == TIM6)
{

}
/* USER CODE END Callback 1 */
}

HAL_ADCEx_MultiModeStart_DMA(&hadc1,(uint32_t *)adc_data,256);
first_time_start = 0 ;
}
sent_bytes [1] = sent_bytes[1] + 10 ;
sent_bytes [2] = sent_bytes[2] + 10 ;
sent_bytes [3] = sent_bytes[3] + 10 ;
Send_Via_USB( sent_bytes , 1408 ) ;
