【平头哥RVB2601创意应用开发】超声波压感sensor调试和LED/OLED显示 [复制链接]

1. 时间过得真快啊，转眼两周了，今年的五一很特别，继续封控，哈哈，希望早日解封吧。

2. 继上次I2C可以正常读取超声波压感sensor数据后，我又很顺利的调试校准了sensor，并通过LED和OLED做了显示。

3. Sensor校准后通过串口抓到的数据如下：

1）初始化

从log可以看到按压时key会从1变成2，在代码里加入如下片段，

	while (1) {

		lv_task_handler();	
        for (i = 0; i < BUTTON_NUM; i++) {
			ccl_tp_dev_t *dev = &ccl_tp_dev[i];

			ccl_tp_if_get_adc(dev);
			ccl_tp_if_get_btn_status(dev);
			
            debug_info("dev%d(%#X) ,adc %d ,%d, key %d[%s]",
					dev->dev_idx,
					dev->i2c_addr,
					dev->info.usp_adc,
                    dev->info.zforce_adc,
					dev->info.btn_status,
					(dev->info.btn_status == 2) ? "pressed" : "released");  
			if(dev->info.btn_status == 2){
				csi_gpio_pin_write(&r, GPIO_PIN_HIGH);
				csi_gpio_pin_write(&g, GPIO_PIN_HIGH);
				csi_gpio_pin_write(&b, GPIO_PIN_LOW);
				lable_press();
			} else {
				csi_gpio_pin_write(&r, GPIO_PIN_HIGH);
				csi_gpio_pin_write(&g, GPIO_PIN_HIGH);
				csi_gpio_pin_write(&b, GPIO_PIN_HIGH);	
				lable_release();
			}
		}
        	debug_info("\r\n");
			aos_msleep(10);
			lv_tick_inc(1);	
			
	}
	...

即https://bbs.eeworld.com.cn/thread-1198665-1-1.html里关于LED的控制，可以看到如下视频的效果：

4. 为了进一步加强交互体验，我还加入了OLED的显示，代码如下：

lv_obj_t *p;
static void lable_test(void)
{
    p = lv_label_create(lv_scr_act(), NULL);
    lv_label_set_long_mode(p, LV_LABEL_LONG_BREAK);
    lv_label_set_align(p, LV_LABEL_ALIGN_CENTER);
    lv_obj_set_pos(p, 0, 4);
    lv_obj_set_size(p, 128, 60);
    lv_label_set_text(p, "THEAD\nMARQUEE\nDEMO");
}
static void lable_press(void)
{
	lv_label_set_text(p, "");
    lv_label_set_text(p, "Press");
}
static void lable_release(void)
{
	lv_label_set_text(p, "");
    lv_label_set_text(p, "Release");
}

最终的视频效果如下：

5. 以上就是我计划完成的作品：基于RISC-V处理器的超声波压感按键，最后再次感谢EEWORLD和平头哥提供的这次机会。
