hello everybody,
I'm working in a project using the automated generic bootloader example, I want to do some edits so as I can have an input interrupt at any time, I mean for example: when pin 3 is raised to logic one then I can turn on a led ,that's it, I don't know how to edit the code to do the added tasks.
Note that these edits has no dependency on connection or advertising, I mean while advertising I can check the input & then do the function upon the check, while connection, it doesn't matter & for me to check the input signal at all.
can I do that??
here is the main function:
/**@brief Function for bootloader main entry.
*/
int main(void)
{
uint32_t err_code;
bool dfu_start = false;
bool app_reset = (NRF_POWER->GPREGRET == BOOTLOADER_DFU_START);
if (app_reset)
{
NRF_POWER->GPREGRET = 0;
}
//leds_init();
// This check ensures that the defined fields in the bootloader corresponds with actual
// setting in the nRF51 chip.
APP_ERROR_CHECK_BOOL(*((uint32_t *)NRF_UICR_BOOT_START_ADDRESS) == BOOTLOADER_REGION_START);
APP_ERROR_CHECK_BOOL(NRF_FICR->CODEPAGESIZE == CODE_PAGE_SIZE);
// Initialize.
timers_init();
// buttons_init();
(void)bootloader_init();
if (bootloader_dfu_sd_in_progress())
{
nrf_gpio_pin_clear(8);
nrf_gpio_pin_clear(19);
nrf_gpio_pin_clear(25);
nrf_gpio_pin_clear(29);
err_code = bootloader_dfu_sd_update_continue();
APP_ERROR_CHECK(err_code);
ble_stack_init(!app_reset);
scheduler_init();
err_code = bootloader_dfu_sd_update_finalize();
APP_ERROR_CHECK(err_code);
nrf_gpio_pin_set(8);
nrf_gpio_pin_set(19);
nrf_gpio_pin_set(25);
nrf_gpio_pin_set(29);
//nrf_gpio_pin_set(UPDATE_IN_PROGRESS_LED);
}
else
{
// If stack is present then continue initialization of bootloader.
ble_stack_init(!app_reset);
scheduler_init();
}
dfu_start = app_reset;
// dfu_start |= ((nrf_gpio_pin_read(BOOTLOADER_BUTTON) == 0) ? true: false);
if (dfu_start || (!bootloader_app_is_valid(DFU_BANK_0_REGION_START)))
{
nrf_gpio_pin_clear(8);
nrf_gpio_pin_clear(19);
nrf_gpio_pin_clear(25);
nrf_gpio_pin_clear(29);
// Initiate an update of the firmware.
err_code = bootloader_dfu_start();
APP_ERROR_CHECK(err_code);
nrf_gpio_pin_set(8);
nrf_gpio_pin_set(19);
nrf_gpio_pin_set(25);
nrf_gpio_pin_set(29);
}
if (bootloader_app_is_valid(DFU_BANK_0_REGION_START) && !bootloader_dfu_sd_in_progress())
{
// Select a bank region to use as application region.
// @note: Only applications running from DFU_BANK_0_REGION_START is supported.
bootloader_app_start(DFU_BANK_0_REGION_START);
}
NVIC_SystemReset();
}
note that advertising functions , gap params are defined in dfu_ble_transport.c
