project not working

[Noel]

Hello,

I'm trying to recreate the PWM_library example from the v.11 SDK in a new file in Keil. I have compared the debug settings in my project to the debug settings to the project in the SDK, and almost everything matches (there are some understandable exceptions there). I am able to download this project onto the nRF52; however, the Leds do absolutely nothing, compared to when I run the actual example - then the Leds do what they're supposed to do. I thought it may have been because of this: devzone.nordicsemi.com/.../

, because I also have that error but I am able to compile and download the code beside that (and the responder stated that it wasn't a real problem). Any suggestions as to how to debug this?

Thanks,

Noel

Hi Noel

The best thing to do is to start the debugger and see if the code execution halts somewhere, or if there is an error code returned from any function. To set up debug, look at this thread and this blog.

Thanks Stefan! I've debugged it and it has not yet returned any error codes. I was pressing "F5" to run through it in debug mode and it seems to do as it is expected (Leds 1 and 2 have reverse polarities so as one gets brighter the other gets dimmer). I noticed also that when I start in debug mode, and then exit debug mode, the program seems to run fine on its own. However, when I click load to download the code onto the board, the leds still do nothing. Any thoughts?

Thanks,

Noel

hello,

I found out that it was because in the utilities tab of the "options for target" window, clicking the "settings" button, it had a default size for "RAM for Algorithm" that was larger than that set for the example. Thanks!
