uart.write("ESP32C3 data, count: %s"%cnt) time.sleep_ms(1) 上面的代码中,第4行代码,为初始化串口1,可以看到波特率设置的为115200,rx引脚为GPIO01,tx引脚设置的为GPIO00。其他的参数都是默认值,如奇偶校验位设置为无校验,停止位设置为1。

从步聚B到F,其实可以用一个 esp_http_client_perform 函数一步到位。它会自动调用 从open,到 fetch,到 write、read,到 close 等方法。 不过,咱们这里向服务器请求的是 PCM 音频流,数据较长,不能一次就读完,咱们要读一点,然后发到 I2S 播放,然后再读后面的。所以就不能用 esp_http_client_perform 函数了...
_serialDevice.WriteTimeout =500;for(; ; ) { _serialDevice.WriteLine(DateTime.UtcNow +" hello from nanoFramework!"); Thread.Sleep(2000); } } 编译并部署上面的代码到 ESP32 板子,点击 RESET 按钮程序就会启动。此时我们连接串口即可看到打印的 Hello World 信息。
