What is the purpose of LED_START and LED_STOP lines in pca10028.h?

I need to add two more led pins - #10 and #30 - to that board, but I don't know what to do with LED_START and LED_STOP lines, and so far, it is difficult for me to trace any occurances of those two in my project.

I'm looking at the schematic and don't see anything called LED_START nor LED_STOP. According to the schematic p0.10 is used for RTS which you are allowed to repurpose as a LED as long as you don't need flow control and p0.30 is used for SDA which only matters for i2c.

If you are referring to LED_START as a code event, then you will need to be more specific in your question.

Yes, I meant the lines in the code. I discovered an advanced search functionality in Segger Embedded Studio, and i checked up - there are no occurances of those lines in my project, so probably that doesn't matter at all. Thank you!

Those refer to the beginning and ending numbering for the start/stop of the led gpios. You will find them referenced in boards.c Personally I found that a difficult way to deal with the driver. You can always just config the gpio yourself in code. That is what I do. Just keep in mind that if you are actually using p0.10 and p0.30 then you will need to deal with the loss of RTS and SDA. eg, if you use the uart it will change the mapping of p0.10
