Migrating PWM driver nRF52840 to nRF52833

[TedLee]

Hi everyone

I want use the pwm_driver example of the SDK download at nRF52833 DK

However, some problems were encountered after the migration

 I replace the preprocessor flag "NRF52840_XXAA" with NRF52833_XXAA  and "BOARD_PCA10056 " with "BOARD_PCA10100 "

and the memory:

FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0x80000
RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x20000

I build the project and download at my 52833DK,but no log info print and LED are not on.

I turn on DEBUG and I can see it's running

Please give me some suggest 

Thanks and Best regards！

Hello,

There is no direct way of doing this, so you either need to (option1) modify an nRF52840 project (pca10056) to be an nRF52833 project (pca10100), or alternatively (option2) start with a project that already support nRF52833 (pca10100), and then include the source files and sdk_config.h from a project that support the nRF52840 (pca10056). Some devzone cases that discuss either or both options:

 nRF52833 development 
Creating SES projects for PCA10100 or other boards 
Can I use the example code for PCA 10056 for PCA 10100? 

Best regards,
Kenneth

HI Kenneth 

I'm sorry for the delay in my reply。

Thank you for your advice suggest，and the code compiled passes，but LED is not display。

Thanks and Best regards！

That was odd, if you have set board BOARD_PCA10100 instead of BOARD_PCA10056, then it should choose the pca10100.h from \components\boards

But it could be the example doesn't use the board file, and instead are hardcoding LED pins by other defines.
