It is good practice to prefix all functions from a C library with a prefix, to avoid collisions with other libraries that the end-user may link with. Unfortunately the Nordic...
It is good practice to prefix the includes from one's C libraries with a directory so that they are all part of the same 'include namespace'. Unfortunately the Nordic SDK...
Hello,
I need to read by Battery Voltage using ADC. My Battery is 3.3v which is being stepped down to 2.1V using a LDO regulator. So my VDD is 2.1V in DC/DC mode.
Now I...
Hi guys I'm sending data from an nexys 4 fpga through an spi to my nRF51 (pca10028) I have the fpga set as the master and I'm able to read data sent to the nRF51 through my...
Hi.
I'm using nrf52 as slave for another device. I'm reading test string from the nrf buffer and I can see extra zero (rest of the content is then offset by one -> corruption...
Hi, i know this question has been ask before but, i was reading and readind and i could find a way to do it. I got the theory but when i'm going to implement it in my code...
