STM32H743 Can BDMA trigger a DMA2 transfer

I already set up a SPI1 Tx and Rx with MDMA and DMA2 moving data from DTCMRAM to RAMD2 to SPI1Is it possible to do the same with SPI6 ?I see that DMA2 can access APB4 peripherals (including SPI6) but "sp6_rx_dma" and "spi6_tx_dma" hardware requests a...

Resolved! I want to send 16-bit numeric 16-channel data measured by ADC with BLE. However, when programming according to the BLE example, the transmitted data is in the form of 8 bits. What is the general way to solve this?

I want to send 16-bit, 16-channel data measured by ADC. but I realize BLE is transfering 8bit data. How can I solve this?my key script is below.<main.c>uint16_t DMAo[16];​ HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED); HAL_ADC_Start_DMA(&hadc...
