I would like to be able to generate DTMF tones using PWM. I am very familiar with the process, having written code to do this several times on other devices. The DTMF will...
Is it possible to use the nrf51 dongle with raspberry pi b+ ? I'm prototyping a 6LoWPAN solution where the peripheral nodes are nrf51 devices. I'd prefer the central device...
Hi, I'm not used to the bsp.c so my question could be silly. I hope you could understand.
When I used SDK 6.1, the example about button_event_handler function had a parameter...

How can I read the Bluetooth clock (piconet) which is synchronized between the master/slaves in the piconet ? I need a constant (micro second accuracy) time from when I do...
Hello,
Is it possible to know the preamble , data format and the CRC calculation to interface a radio system ( GFSK Manchester) with NRF905 ?
Thank you
I'm wondering if the port and pin function can be used together to configure a set of pins.
For _port_dir_set, I assume it sets the whole port to the designated direction...
