[Pawel]’s project makes use of TinyWireS, a slave-mode SPI and I2C library for AVR ATtiny Arduino projects. This is my function to read the EEPROM data. 3-wire LCD 433MHz 5V Power Supply Adafruit GFX Arduino Arduino Clone Arduino Due Arduino Micro Pro Arduino_STM32 Blue Pill Board Bootloader BPB DCF77 Debugger DIY DS1307 DS3232 Freeduino GLCD 128x64 HC-SR04 I2C ICSP ILI9143 ILI9341 ISCP ISP Knight Rider LC Meter LCD LGDP4535 LM7805 MAX232N Nokia 5110 LCD NPN PNP Tester Paper-PCB Paperduino-Uno. The slave is very simple, when master write data byte 0x01 to it, then the LED on Arduino board will blinking every 250 ms. Briefly, I was using a DS1307 and 24c32 Module with built in pull-ups. Logic Analyzer, for Arduino, other AVR and STM32 with a very nice working processing interface, you could run it also on any Android device. Circuit Diagram. But when we go deeper we understand that Arduino is not industry ready development board and its 8-bit CPU with a ridiculously slow clock and may be not suitable for higher level projects. For do this follow the steps below. The alternative connection is SCL-PB6 (D10) and SDA-PB7. and how to use it with the Arduino board. Arduino : howto master to master I2C 25 May 2013 Electronics master , multi-master , twi Michael I’ve been working since many weeks (months) on designing a home automation “box” project, and could hardly find a way to get my Arduinos (actually bare ATMega328 + Arduino’s Optiboot bootloader) communicating together without having the. “Dial 6 to switch off the light in living room. The Arduino uses 7bit I2C addresses, and our own documentation uses 8bit addresses. The SRF08 communicates with an Arduino over SPI/I2C. the LTC4151, after 33 ms). I2C Bus Pullup Resistor Calculation Figure 1. As promised, today I am going to interface LCD to STM32 using an I2C device (PCF8574). 5 inch OLED Shiled is fit to STM32, Arduino and Raspberry pi etc, and it uses SSD1327 as driver chip, and interface is i2c, and provide some sample source code and PCB Schematic. Очевидно, что отладочная плата на базе STM32 выигрывает по всём параметрам у Arduino Nano, исключением является разве что стоимость, но согласитесь 10 центов — хорошая цена за большую. (optional Arduino debugger and more!). It consists of a 1602 white character blue backlight LCD. Moreover, with I2C module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. Само собой разумеется, не всякая библиотека, написанная под Arduino, так просто возьмет и заработает под STM32. Arduino is the popular open-source electronics prototyping platform based on easy-to-use hardware and software.
