Issue in configuration of Button in NRF51822 board

[Rohit]

Hello All,

I am working on the NRF51822 custom board.

I am Using the SDK 12.3 with s130 (PCA10028)

1.) Is it right sdk for nrf51822..?

2.) Facing issue in configuration in button after changing pins configuration w.r.t schematic in pca10028.h file.

Attaching the pca10028.h and schematic.

Please check and give your inputs.

1.schematic

SCH-W912N - 副本.pdf

2. pca10028.h

pca10028.h

Thanks,

Rohit

Hi Rohit

I've taken a look at your schematics, and here are some notes:

• C3 should be 47nF
• R2 is 1kOhm in the reference design, but 12kOhm should be fine as well.

Other than that, everything seems to be correct. Now, to your questions.

1. Yes, SDK 12.3 and S130 are the most recent SDK and SoftDevice that are compatible with the nRF51 series products.
2. What are you asking here? Do you want to You can set the buttons to any GPIO by changing #define BUTTON_X to whatever pin number you want. In any case, this is the correct pca10028 file.

Best regards,

Simon

Thanks Simonr for your reply.

I will consider your input for the hardware design change.


Yes , I wanted to do configure button as per schematic i.e. 19 pin.( i have made changes in PCA10028)

But after configuration also it is not working.

what changes i have to do in the PCA10028.h file?

Waiting for your reply.

Thanks,

Rohit

Hi Rohit

Sorry I didn't catch that. It seems you've mixed up the pins and pin names. If you take a look at the pin assignments in the product specification, you can see that pin 19 = P0.13. I see that your button is on P0.19 in the schematics, which means you'll have to configure it as 27 in the pca10028.h file.

Best regards,

Simon

Thanks for your inputs.

As per you suggestion i have made changes. 

But after using the sdk 12.3 with s130 i am getting  following error 

As i have imported example from keil5 folder in segger embedded studio
