Dialog Smartbond Bluetooth Low Energy – Software

Hello,
I want to transmit a big amount of data to USB. I am using USB_CDC example project for this but with this example the throughput is about 700 KBps. Is there any way to speed up the USB CDC throughput? Does the DMA helpful? If yes, How to initialize and use DMA with USB_CDC?

Thank you in Advance.

Hi Dialog,
Does the internal DMA of DA1468x support input from GPIO? if yes, how to initialize the trigger of DMA? what can I do if I want to trig DMA with timer0 clock and the source of GPIO->P4_DATA_REG?

Hi,
I am using the DA1468x_SDK_BTLE_v_1.0.6.968. Is there any project in the sdk that uses the DMA service at the ADC?
Thank you in advance.
