Hi Jared

I didn't create any project from scratch. I simply opened the project that you shared on that thread.
I will try your suggestions and get back to you asap.

Thanks

Hi,

The error log that you shared indicates that the compiler is not able to find either boards.c or nrf_log_frontend.c.

The example should already use board.c so I'm a bit surprised that it says that it couldn't find it.

When adding files to your Segger project you have to:

1.Add the source file to the project by using " Add Existing File":

2.Then you have to add the path to the source file to the project build:

best regards

Jared

If i simply download the file you provided on another thread then it gives me this error

Hi,

Can you specify the error that you get? Can you share the log output?

Hi Jared
I am OK to use RTT but if you saw my previous response. It is also giving me some error if i compile them. Can you tell me what i am missing?

Hi there,

Previously we agreed on changing the backend from UART to RTT right? If you changed the backend by configuring the sdk_config.h file as I suggested in the previous thread, then you have to use RTT viewer to see the log output.

Hi Jared
Can you give me your feedback for the basic solution please?
Thanks

Hi Jared
I downloaded nRF5_SDK_17.1.0_ddde560

The above code i downloaded from the link you prvoided to convert UART to RTT

I also have on board UART pins available.
UART_RTS
UART_RX
UART_TX
UART_CTS

Let me know if i can use these pins to readout UART data through FT232 module

Also, i am using 3rd party module BL652

I contacted them. They told me that i am developing code based on nRF52 SDK or DK so i need to consult Nordic. I don't want to buy their proprietary DVK because i want to get familiarize with Nordic chips to use in the future projects

Which SDK version are you using?

[quote user="alleekhaan"] don't have USB port on custom board. I am programming it with JTAG with the help of nRF52 DK.
I want to see if analog function is working or not.
Now in the above code, i guess, it read analog value and then print on UART.
As i said, i don't have UART so i need a way to test analog.[/quote]

You change the log module backend to use RTT instead of UART. RTT logs will be sent over the SWD J-link interface. You can view it by opening RTT viewer.

You can change the backend by following this,

There is no reason of using nRFSDK. I just found a tutorial and followed it up.
If you want me to use connect SDK. i am open for it.

Hi Jared

I want to test analog pin function.
I don't have USB port on custom board. I am programming it with JTAG with the help of nRF52 DK.
I want to see if analog function is working or not.
Now in the above code, i guess, it read analog value and then print on UART.
As i said, i don't have UART so i need a way to test analog.
There are two ways.
1: control fade led with analog pin(i have potentiometer connected)

2: somehow print analog value to a serial monitor either through bluetooth or someway.

Can you recommend any example for it?

It is just for testing of analog pin.

Thanks

Hi there,

What exactly didn't work with the example?

I see that you haven't included the part that toggles the LED, are you looking for an example on to toggle a LED?

Is there a specific reason for why you're using nRF5SDK and not nRF Connect SDK?

regards

Jared
