Hi,
usbd_cdc_acm project implemented UART over usb, which is great. However it cannot send bytes from PC to DK board, only DK board back to PC.
In order to implement sending...
I use the SPIM to access a nand flash memory device. There are times, when I need to "free" the SPI bus allocated by the nRF52840, so that another CPU can access the memory...
