I have created a custom board containing the nRF52832. I have two copies. The first board works, meaning that I have flashed the code to it using the DK52, and I can power...
Hello,
I have been evaluating the nrf9160 DK board. And my application is using mbedtls (vanilla) and TFM (Used https_client as a starter project). The problem is that with...
Hi,
I'm new to nRF/Zephyr development and trying to integrate the OV7670 camera with the nRF52840 board. Since there was no driver for this particular camera I ported the...
I'm having a problem with what should be a very simple exercise. I'm trying to compile the Zephyr sample subsys/cpp/cpp_synchronization after adding #include <string> to the...
Hello,
I am trying to read data from LS2DE12 accelerometer MEMS chip via I2C bus and I am seeing only zeros for all 3 axes.
