I2C通信で遊んでみたいと思い、約30年ぶりにマイコンに触れる。約30年前の当時とはハードウェアもソフトウェアも大きく変わった。2021年に発表されたRP2040というマイコンと、最近流行りのPythonのマイコン版であるMicroPythonというプログラミング言語を使い ...

Already back 2019 I have developed a working I2C slave implementation where master can read/write to address memory. BTW, this is still not working in Espressif IDE examples or Arduino Wire examples.

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 ...

Several of the Mid-Range Enhanced Core PIC16 microcontroller devices have a Master Synchronous Serial Port (MSSP). The MSSP module can be used to implement either I2CTM or SPI communications protocol.

Complete schematic for interfacing I2C LCD and 4x4 keypad with Raspberry Pi zero W is shown in below image: First, we will discuss about 4x4 keyboard. The matrix of the keypad has four rows and four ...
