Keil - first project

[Robert]

Hi, I'm working on setting up project inside uVision. I have added all files with headers, and when I try to compile this is what I got:

    ..\SDK10.0\components\libraries\uart\app_uart_fifo.c(117): error:  #20: identifier "UART0_CONFIG_PSEL_TXD" is undefined
      nrf_drv_uart_config_t config = 
RF_DRV_UART_DEFAULT_CONFIG;

      nrf_drv_uart_config_t config =

      nrf_drv_uart_config_t config = 
RF_DRV_UART_DEFAULT_CONFIG;

When I try to "Go to definitione of .. it seems to finding header file.

Can anyone point me what I'm doing wrong ?

Thank you!

Just a shot in the dark here, but I'm assuming it found the header file "nrf_drv_config.h"? I also assume that you can find this in the header file:

/* UART */
#define UART0_ENABLED 0

Change 0 to 1, otherwise the UART0_CONFIG_* defines are left undefined. Also remember to change the TXD/RXD pins to match your circuit etc.

Thank you, it seems to work. Unfortunately I have another issue:

 compiling app_timer.c...
 ..\SDK10.0\components\libraries\timer\app_timer.c(62): error:  #39: division by zero
STATIC_ASSERT(sizeof(timer_node_t) == APP_TIMER_NODE_SIZE);

[atune]

I'm assuming you need to either

• change APP_TIMER_NODE_SIZE in app_timer.h to 36(? check the size of timer_node_t)
• change the == to <= since it's ok that the macro is bigger (it's like that in e.g. nRF52 SDK 0.9.2)

Thank you! Of course next issues happen:

Error: L6218E: Undefined symbol ble_srv_report_ref_encode (referred from ble_bas.o).
Error: L6218E: Undefined symbol pstorage_access_status_get (referred from ble_advertising.o).
Error: L6218E: Undefined symbol assert_nrf_callback (referred from app_button.o).

I have ble_srv_common.h imported.

Well this time my guess is that you need to add the relevant .c files containing those functions into the project so that they are compiled for linking. :)
