c questions - sending multiple bytes to and from arduinos

The Arduino sketch does delay the I2C slave communication of the Arduino accidentially in it’s loop() method. If you would only read the temperature when really needed or by breaking up the “delay(100);” into a more sophisticated non-blocking delay (shorter delay or only read temperatures every 100 milliseconds by using the “millis()” method) the responsiveness of the Arduino as the

當程式下載到 Arduino 後會發現完全沒有畫面! 一開始我想到的有兩件事 1. 線有沒有接對? →才兩條線,檢查了十次,把他們交換了,還是完全沒有畫面 2. I2C Address 有沒有正確? →用電錶檢查了 A0, A1, A2 電壓都在高準位,應該沒問題

Tutorial 07 for Arduino: I2C Communication and Processing

I am using Python smbus write_word_data method to send int values from a Raspberry Pi to an Arduino using IC. . This seems to be the correct method. When I send values from 0-255, I see the following in my Arduino serial monitor. 0,0,0 0,1,0

Arduino I2C Tutorial: Communication between two Arduino Boards

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1).

Most hobby market I2C sensors only have a 12-bit ADC, and since memory is a limited resource there are often status register bits mixed in with the data held in the MSB. Since these bits are not part of the sensor reading, you need to LSB.
