Hi,
I want do RSA on NRF51822. The build environment is GCC. And the develop base on S120. The RSA need 1K to do calculation. If I enable the RSA calculation, the APP may...
Is there any high-level documentation of the nRF52-DK (PCA10036) connections?
Studying the schematics, I have inferred some of the intents, like:
built-in JLink automatically...
Hello,
I'm starting a new nRF51 project on mbed for a custom board. I wish to know what is the "cleanest" way to define pinout (what file to edit) ?
Thank you
Hey,
I'm working on integrating nrf8001 with STM32, currently trying to write my own stack.
Upon reset, I read the DeviceStartedEvent, 0x81 and it shows "0x02 0x00 0x02...
