【平头哥RVB2601创意应用开发】超声波压感sensor调试和LED/OLED显示
<p>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。</p><p> </p>
<p>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。</p>
<p> </p>
<p>3. Sensor校准后通过串口抓到的数据如下：</p>
<p>1）初始化</p>

<p>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，</p>
<pre>
<code> while (1) {
lv_task_handler();
for (i = 0; i < BUTTON_NUM; i++) {
ccl_tp_dev_t *dev = &ccl_tp_dev;
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);
}
...</code></pre>
<p>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：</p>
<p><iframe allowfullscreen="true" frameborder="0" height="510" src="https://training.eeworld.com.cn/shareOpenCourseAPI?isauto=true&lessonid=33220" style="background:#eee;margin-bottom:10px;" width="700"></iframe></p>
<p>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：</p>
<pre>
<code>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");
}</code></pre>
<p>最终的视频效果如下：</p>
<p><iframe allowfullscreen="true" frameborder="0" height="510" src="https://training.eeworld.com.cn/shareOpenCourseAPI?isauto=true&lessonid=33221" style="background:#eee;margin-bottom:10px;" width="700"></iframe><br />
5. 以上就是我计划完成的作品：<strong>基于RISC-V处理器的超声波压感按键</strong>，最后再次感谢EEWORLD和平头哥提供的这次机会。</p>
<p>最后的那个最终的视频效果好像确实有点状况</p>
