Arduino Unoでは、PA4、PA5をI2Cに使用するので、I2C通信を使う場合は、アナログ入力としてはこれらを使用できません。 shieldで良く使われるSPI。 ICSP(In Circuit Serial Programming) Pinは、PD11 - PD13と物理的に繋がっており、SPI通信に使われています。 SPIを使用する時は ...
This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
