远程控制器由Arduino开发板和带有NRF连接器和电源的板组成,这个板将被安装在Uno上方,以避免使用电线。 图2:远程控制器原理图 图3:远程控制器PCB 图4:安装有连接到Arduino Uno 的NRF24L01+模块的远程控制器 您还会看到我们安装的两个LED灯,用来指示电路的功能和上述的其他组件。我们将会使用一些用于稳压器和NPN晶体...
F1和F4飞控根本没有内置反相器,因此任何UART都可以直接使用;对于F3和F7飞控,INAV / Betaflight固件可以禁用软件中的反相。程序中采用“ FASSTest 18CH”协议的Futaba S.Bus 编码16个RC通道和2个数字通道(ON / OFF)。 SBUS的每个RC通道值映射为:-100%= 173(相当于PWM伺服信号中的1000)0%= 992(相当于PWM伺服...
我包括一个 3.3V 稳压器和一个NRF24L01收发器模块的连接,以防我们想使用该模块控制平台。此外,我还包括一个 12V 电源轨,以及 5V 和 6V 电源轨,并带有数字引脚连接,用于将伺服电机连接到它们。6V 电源轨可由一个外部降压转换器供电。 我从PCBWay订购了PCB。在这里,我们可以简单地上传 Gerber 文件, 选择我们 PCB...

nrf24l01模块也需要同时睡眠和醒来,使用Mirf库里的powerDown()命令。 实测电流:pro mini 5v版本,3.7v锂电池供电,HT7533稳压,LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF)同时Mirf.powerDown(),电流1.48mA。 传感器供电:如果直接将传感器接在5v或3v3上,传感器会一直消耗电流。为了节电,可以将对电流要求不高的...

CSN是一个“片选择引脚”,即Chip Select N(N代表低电平有效),假如你想通过1个NRF24L01同多个NRF24L01进行通信的话,就需这个引脚了。一旦将想要通信的那个NRF24L01模块的CSN引脚置0,就代表你之后所有的信息传输对象针对的是这个NRF24L01模块。这就好比你是一个管理员,然后你要管理一群聋子,咋办呢?你喊他们名字肯定是...
This library is an attempt to make the NRF24L01+ and its clones understand each other. Simple example: buttons and LEDs 3 different radio modules connected to 3 Arduinos. You press a button on any of them, and the pin13 LED of the other 2 will light up. You release the button, and ...
Onboard 5v and 3.3v regulators give you plenty of power for your projects Onboard ESP-8266 model-12E pre-installed - adds WIFI functionality Dedicated port for BT-12/HC-05/HC-06 Bluetooth master/slave module (module not included) Dedicated port for NRF24L01+ 2.4ghz radio transceiver (module...
The entire system is divided into two parts, the car and the remote control, the communication between them based on NRF24L01 2.4G wireless module. In the remote control mode, you can control the smart car through the remote control, so that the car forward, back, turn left and turn right...
