First, I’ll quickly explain what is Serial communication. Then you’ll see how to setup your hardware and software, and we’ll dive into the Python code (Cpp for Arduino). A basic example at first, leading to a more complete application using a Raspberry Pi, an Arduino, and other elec...
(from an interrupt handler) allowing your sketch code to immediately resume processing. This is usually a good thing (it can make the sketch more responsive) but sometimes you want to wait until all characters are sent. You can achieve this by callingSerial.flush()immediately followingSerial....

SPI,是英语Serial Peripheral interface的缩写,顾名思义就是串行外围设备接口。是Motorola首先在其MC68HCXX系列处理器上定义的。SPI接口主要应用在 EEPROM,FLASH,实时时钟,AD转换器,还有数字信号处理器和数字信号解码器之间。SPI,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,节约了芯片的管...

IMPORTANT: READWHAT'S NEW IN V2Some major changes are made in V2 of the SX126x-Arduino library: - The library now supports all LoRaWAN regions without re-compiling - The interrupt handling for SX126x IRQ's are taken into separate tasks for ESP32, nRF52 and RP2040 ...
tmf8828_calib.handtmf8828_calib.c- a device specific set of factory calibration data (needs to be generated for each device, as it depends on the serial number of the device) You can use application interrupt driven. For this you need to set the following define to 1:USE_INTERRUPT_TO_TR...
1, CH375B is a USB bus interface chip with 8-bit data bus and read, write, chip select control lines and interrupt output can be easily attached to the microcontroller / DSP / MCU / MPU system bus controller, etc. . In USB host mode, CH375B also provides serial comm...
