Need to test USB communication with nRF52840 EVK

[Srikara]

Hi

My device and Software details are as below

nRF52840 EVK

Softdevice:s140

SDK v16

I am new to BT and USB protocols. 

As part of our POC I eed to test and establish the USB communication with nRF52840 module.

I want to know the initial steps to understand and verify the USB communication with the EVK.

Hi,

nRF5 SDK v16 is quite old. However, I would not suggest that you upgrade to a newer version of nRF5, but rather consider using nRF Connect SDK (NCS) instead of nRF5 SDK. 

Regarding USB communication, you could try out existing NCS v2.0.0 Zephyr samples located in \2.0.0\zephyr\samples\subsys\usb.

Best regards,
Dejan

Hi 

Thank you for the response. But we are using SDKv16 for some other use case. Now we need to use the same SDK for testing USB. My query is complete steps to bringUP USB and test it on nRF52840 board. Not able to understand which examples of SDKv16 i need to use to test. Further we need to bring up SPI and UART also

Hi,

There are many hardware peripheral examples including USB examples (USB HID example and USB BLE UART example), UART example, SPI master example and SPI slave example.

Thank you.

 I think J3 is the connector for USB communication. I want to use this for basic data communication.

Connect USB here to Laptop and test the USB data transfer. For this I want to know the best example to use.  Shal use this:infocenter.nordicsemi.com/index.jsp

Hi,

USB samples that I mentioned previously may be a good starting point. Additionally, you may want to look at USB Device example.
