Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
Hi,
We're using nRF51822 and in the future we'll use nRF52832.
We do use bluetooth, but as far as I know, we don't use encryption (code is based on the HRS example, and...
Is nrf52 support 3 wire spi interface? I am using AD9837 3-wire spi module act as slave and nrf52 dk act as master. I am using SCLK, SSn(i.e.,Fsync) & MOSI pins only.I want...
Hi, I’m a newbie of nRF SoC. I have a BLE gadget with nRF51822_xxAC that controls LEDs and obtains data from accelerometers through I2C(TWI) devices. The hex file for the...
Hello,
