Use of header file for bare chip programing

[Vishwas Jain]

I am working on custom programming of nRF52832. I have little experience of Preview DK. I took help of examples in SDK v15 and came across nrf_pwr_mgmt.h header file which controls shutdown process.

So, my question is, Does this file only controls only the shutdown process of DK/Preview DK or can it be also use for bare chip programming?nrf_pwr_mgmt.h

Hi,

The Power Management library can be used for any project that use a nRF5x chip. (This is the case for most other SDK modules as well, except for the  Board Support Package (BSP) which is board specific, with a separate header file for each supported board).

Thank you for your reply.

I know that BSP library is for board. So, it won't be supportive for other projects. Can you let me know which other changes

 overall should I make in example file ?

From changes, I mean is, not including some .h file, some class(like log_init(), if I am correct) in main.c etc

Hi,

There are only a few things you should do to adapt a SDK project to a custom board:

• Configure the LFCLK correctly for your HW in sdk_config.h (RC or crystal, and if crystal specify the accuracy). SDK examples enable the 32 kHz crystal by default.
• Adapt pin configuration for peripherals such as UART, TWI, SPI etc. as needed. In most cases this is set in your projects sdk_config.h
• Enable DC/DC if you have the necessary components on your HW. The DC/DC is not enabled by default.
• Remove the BSP. Handle buttons and LED using the GPIOTE driver and Button handling library instead.

This will help me a lot through out my project.

Thank you for your support!
