Hi All,
I'm using nrf52 PCA10040 v 0.9.0, with SDK11. No softdevice being used in this case.
While exploring using EasyDMA with the SPI peripheral, the example in sdk11...
Hi there,
this problem may extend the scope, as it relates the SPI slave device (atmel winc1500). When I run the SPI master example, I can see the data transmitted on oscilloscope...
Hi, I use S110 v8 in my application with DFU support. When DFU is triggered from application (by writing 0x0104 to DFU service control characteristic), then application fails...
Working on a project i want to update the nordic application (firmware) from other MCU, i am having some problem to compute the crc.
How to we calculate the crc of...
