Arduino Pinout Reference说明书
CLK是SPI接口的串行时钟引脚。 VCC引脚为LCD提供电源,我们将其连接至Arduino上的3.3V电压引脚。 BL(Backlight)引脚控制显示屏的背光。要控制其亮度,您可以添加一个电位计或将此引脚连接到任何具有PWM功能的Arduino引脚。 GND应该连接到Arduino的地 将诺基亚5110 LCD显示模块连接到Arduino Uno ...
SPI 接口: 下载程序 Arduino UNO上的ATmega328已经预置了bootloader程序,因此可以通过Arduino软件直接下载程序到UNO中,参见[[]]。 可以直接通过UNO上ICSP header直接下载程序到ATmega328,参见[[]]。 ATmega16U2的Firmware(固件)也可以通过DFU工具升级,参见[[]]。
该文件是Arduino的编程入口,提供setup和loop函数。在loop函数默认以200ms为周期,闪烁Arduino内建LED灯(LED_BUILTIN)。如果该BSP默认支持SPI功能且为UNO引脚布局,由于SPI和LED_BUILTIN可能存在冲突(D13),可以在loop函数内以Serial.println("Hello Arduino\n");代替频闪LED(例如STM32F401 Nucleo板)。

SPI:Pins 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) support SPI communication using the SPI library. They are also broken out on the ICSP header, which is compatible with the Uno, Duemilanove, and Diecimilia. LED:Pin 13 connects to the built-in LED. Whe...
Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.Revision 3 of the board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the...
