以下是基于nrf52832的空中升级(OTA)代码示例:
```
#include <stdint.h>
#include <stdbool.h>
#include "nrf.h"
#include "nrf_sdm.h"
#include "nrf_gpio.h"
#include "nrf_delay.h"
#include "nrf_drv_clock.h"
#include "nrf_drv_power.h"
#include "nrf_dfu.h"
#include "nrf_dfu_flash.h"
#include "nrf_dfu_handling_error.h"
#include "nrf_dfu_settings.h"
#include "nrf_dfu_transport.h"
#include "nrf_dfu_utils.h"
#include "nrf_dfu_validation.h"
#include "nrf_bootloader_info.h"
#define LED_PIN 13
static void leds_init()
{
nrf_gpio_cfg_output(LED_PIN);
}
static void leds_on()
{
nrf_gpio_pin_clear(LED_PIN);
}
static void leds_off()
{
nrf_gpio_pin_set(LED_PIN);
}
/**
* @brief Function for application main entry.
*/
int main(void)
{
uint32_t err_code;
// Initialize the clock.
err_code = nrf_drv_clock_init();
APP_ERROR_CHECK(err_code);
// Start the low-frequency clock.
nrf_drv_clock_lfclk_request(NULL);
// Initialize the power module.
err_code = nrf_drv_power_init(NULL);
APP_ERROR_CHECK(err_code);
// Initialize the LED pins.
leds_init();
// Wait for the power module to be initialized.
while (!nrf_drv_power_usb_detected())
{
nrf_delay_ms(100);
}
// Turn on the LED.
leds_on();
// Initialize the DFU module.
err_code = nrf_dfu_settings_init(true);
APP_ERROR_CHECK(err_code);
// Register the transport layer.
err_code = nrf_dfu_transport_register(nrf_dfu_uart_transport);
APP_ERROR_CHECK(err_code);
// Start the DFU module.
err_code = nrf_dfu_init();
APP_ERROR_CHECK(err_code);
// Turn off the LED.
leds_off();
// Enter the main loop.
while (true)
{
nrf_dfu_continue();
}
}
```
以上代码实现了空中升级(OTA)的基本流程,具体实现方式可以根据实际需要进行调整。在使用该代码之前,需要确保已经在芯片中烧录了DFU bootloader,并且已经在固件中添加了OTA升级的相关代码。
