board support package(bsp) Issue

[lakshman]

main.cHI Nordic, I don't want bsp.c in my project. So I removed the bsp.c and included custom_board as mentioned in devzone.nordicsemi.com/.../ I am also using UART for communication. so I add #include "app_uart.h" in main.c changed #if defined(BOARD_CUSTOM)//BOARD_PCA10031 ...... #else .... #endif

My question is if I remove bsp.h in main and also below code. err_code = bsp_init(BSP_INIT_LED | BSP_INIT_BUTTONS, APP_TIMER_TICKS(100, APP_TIMER_PRESCALER),NULL); my code is not working.unable to see UART communication. kindly help me to overcome bsp issue.

also please guide me what is the use of this timer. APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, NULL);

Thanks and Regards Lakshman,PMP,PMI-RMP

can you check first if you can run the uart example SDKXX\example\peripheral\uart? That is not using any bsp or timer modules

HI Aryan, Thanks for your reply. Its working with uart example SDKXX\example\peripheral\uart. But the program not using interrupt. Moreover I am using the ble_uart_c as central. please find the attached main.c

1.removed app_gpiote.h and added nrf_drv_gpiote.h & app_uart.h 2.added Options for target -->......\componmain.cents\ble\ble_services\ble_uart_c (created folder and added ble_uart.c & ble_uart.h above 2 steps to avoid compilation error

3. //Lakshman if i remove below two line UART wont work. APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, NULL); err_code = bsp_init(BSP_INIT_LED | BSP_INIT_BUTTONS, APP_TIMER_TICKS(100, APP_TIMER_PRESCALER),NULL);

kindly advise. I don't want timer and bsp package. I planned to control the gpio directly.

Thanks and Regards Lakshman,PMP,PMI-RMP

Note : unable add main.c file in add a comment. please find main.c in intial question

Found the issue. err_code = bsp_init(BSP_INIT_LED | BSP_INIT_BUTTONS, APP_TIMER_TICKS(100, APP_TIMER_PRESCALER),NULL); after removing bsp package. I forget to remove below code. APP_ERROR_CHECK(err_code);

Thank you for your support.
