【祖传点灯】安信可Ai-M61-32S + 点灯

感谢园长，感谢安信可，第一次中奖，诚惶诚恐 以下是我点灯代码 ```c #include "bflb_mtimer.h" #include "bflb_pwm_v2.h" #include "bflb_clock.h" #include "bflb_gpio.h" #include "board.h" struct bflb_device_s *pwm; struct bflb_device_s *gpio; int main(void) { int i; board_init(); pwm = bflb_device_get_by_name("pwm_v2_0"); gpio = bflb_device_get_by_name("gpio"); /*初始化RGB灯，IO15、12、14，对应蓝灯、红灯、绿灯*/ bflb_gpio_init(gpio, GPIO_PIN_15, GPIO_FUNC_PWM0 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_1); bflb_gpio_init(gpio, GPIO_PIN_12, GPIO_FUNC_PWM0 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_1); bflb_gpio_init(gpio, GPIO_PIN_14, GPIO_FUNC_PWM0 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_1); /* period = .XCLK / .clk_div / .period = 40MHz / 40 / 1000 = 1KHz */ struct bflb_pwm_v2_config_s cfg = { .clk_source = BFLB_SYSTEM_XCLK, .clk_div = 40, .period = 1000, }; /*初始化PWM输出*/ bflb_pwm_v2_init(pwm, &cfg); bflb_pwm_v2_start(pwm); /*功能实现，红、绿、蓝灯依次呼吸循环亮灭*/ while (1) { //红灯呼吸亮灭 bflb_pwm_v2_channel_positive_start(pwm, PWM_CH0); for(i=100;i>0;i--) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH0, i, 100); bflb_mtimer_delay_ms(10); } for(i=1;i<100;i++) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH0, i, 100); bflb_mtimer_delay_ms(10); } bflb_pwm_v2_channel_positive_stop(pwm, PWM_CH0); //绿灯呼吸亮灭 bflb_pwm_v2_channel_positive_start(pwm, PWM_CH2); for(i=100;i>0;i--) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH2, i, 100); bflb_mtimer_delay_ms(10); } for(i=1;i<100;i++) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH2, i, 100); bflb_mtimer_delay_ms(10); } bflb_pwm_v2_channel_positive_stop(pwm, PWM_CH2); //蓝灯循环亮灭 bflb_pwm_v2_channel_positive_start(pwm, PWM_CH3); for(i=100;i>0;i--) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH3, i, 100); bflb_mtimer_delay_ms(10); } for(i=1;i<100;i++) { bflb_pwm_v2_channel_set_threshold(pwm, PWM_CH3, i, 100); bflb_mtimer_delay_ms(10); } bflb_pwm_v2_channel_positive_stop(pwm, PWM_CH3); } } ``` 环境我很久就按教程搭建好了 就不单独再次搭建了 本次代码使用AiPi-Eyes-DU代码中的 PWM 调光代码 以下是我效果图 额外说一些我踩坑的地方， 第一，注释代码 ```c AiPi-Open-Kits/aithinker_Ai-M6X_SDK/bsp/board/bl616dk/board.c ``` 该文件中，第11行 ``` #include "lwip/dns.h" ```  第212行 ``` ip_addr_t dns_addr; ```  第二步，如果串口烧录失败，需要手动给权限，代码 ``` sudo chmod 777 /dev/ttyUSB0 ``` 接下来就欧克了 显示效果
