RS-485、CAN是两种成熟的差分数字串行通讯技术。所谓差分，完整含义是差分数字化（differential digitalization），它是指在一对信号线上，把两条信号线上电平差异的程度定义为二进制0和1这样一种数字编码技术。默认情况下，信号线电平都处于一个平均值附近 ...

在控制舵机上面需要明白一点，其实就是在控制PWM的输出，还有就是控制多少多舵机的事情。 有个神奇的地方，ESP的芯片有专门控制LED的外设，又因为控制LED就是控制的PWM，舵机的控制也是PWM，所以很自然的就会想到用LED的外设去控制舵机。 可以参考官方的 ...

An ideal application for mesh networking is off-grid communication; when there’s no cellular reception and WiFi won’t reach, wide-area technologies like LoRa can be used to create ad hoc wireless ...

Arduino enthusiasts patiently waiting for the arrival of the Arduino PRO Gateway for LoRa will be pleased to know that the Arduino Pro Gateway for LoRa (868 MHz , EU ...

If you are interested in deploying LoRa — the low power long-range wireless technology — you might enjoy [Rui Santos’] project and video about using the ESP32 with the Arduino IDE to implement LoRa.

Pagers may have largely gone out of fashion in the age of the smartphone, but the T-LoRa Pager from LILYGO puts a modern spin on the class communications device. It’s a portable device with a 2.33 ...
