This blog is to demo how to use the external SPI flash for Device Firmware Upgrade (DFU) on the nRF52 Series. The target is to minimize the size of the bootloader particular on the nRF52810. The total size of the bootloader + its setting is only 12KB comparing to original bootloader SDK (32KB). Note: this… Continue reading External SPI Flash Bootloader on nRF52 Series

This blog is to show to use your own custom board instead of original developer board from zephyr. You don't need to use any overlay on the zephyr configuration. For example, if you use the zephyr or Nordic nRF Connect SDK (NCS), you need to check which boards are available by west boards. Basically you… Continue reading Build your customer board on the Zephyr / nRF Connect SDK
This blog is to describe how to add the PDM Microphone on Nordic nRF52 Series. The PDM is started to support on the nRF52832. The pulse density modulation (PDM) module enables input of pulse density modulated signals from external audio frontends, for example, digital microphones. The PDM module generates the PDM clock and supports single-channel… Continue reading PDM Microphone on nRF5 Series
This chapter will take you through the steps required for creating an application in NCS for nRF9160. This blog is based on the Nordic Connect SDK v1.2.0 version. It may have need to change on the other versions (later). The propose of this blog is to show the idea how to run such example on NCS.… Continue reading Tutorial how to create an application on the nRF9160 DK
In this blog, I would like to describe more details on the cmake and west which are the tools in the Nordic Connect SDK. For example, I would cover : Zephyr's Build System How to configure the cmake file with difference parameterHow to use the West to build / flash the application All the materials… Continue reading CMake / West for Zephyr / Nordic nRF Connect SDK
