Arduino example code for 16 channels i2c relay board. The code is for relay board testing purpose. Attention should be paid to: MCP_Write(i, 0x00, 0b00000000); 0x00 is I/O DIRECTION REGISTER for MCP ...

get value function actully sends needed parameters to arduino code for getting value. arduino code then sends that value back using Serial.println() function. but with a prefix ":RTN:". until then, ...

I wrote some I2C sniffer code for a silabs C8051F340 MCU one time. On that MCU, it has specialized I2C hardware, so you only have to peek/poke certain registers to make the I2C bus do what you want.

I will add example code for python/micropython later that shows how to control the I2C bus and the outputs.-- Nederlandse tekst --Schakel signalen, DC of AC met een I2C bus, optisch geïsoleerd met ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finall… ...
