I´m using the RF24.h library in order to develop a system that comunicates in peer-to-peer mode.
When I transmit 3 bytes towards a receiver...
I'm hoping someone can tell me if I'm on the right track. Do I understand correctly that on an nrf51, the LPCOMP can be configured to wake the processor on an analog input...
Hello,
I was wondering how is calcualted or read on the Thingy firmware the variable w for the quaternion used in the Gyroscope readings.
Looking into m_motion.c in the...
The power data of lfclk is measured under the same hardware and software conditions. When we used two model chips, we found a difference of 1 microamps for the value of the...
