WebFeb 24, 2024 · i2c pull up resistors. Since the RPi board already has 1.8K resistors on the I2C lines, any pull-ups included on a breakout board are superfluous and can be removed. On the other hand, they probably won't cause any problems as … WebJan 9, 2014 · For i2c communication either pullup resistor or pull down resistor is connected to the i2c bus line. ... the pull down and pull up resistors are used to keep the …
I2C Communication Protocol Basics Working and Applications
WebEven without the internal pull-ups, a lack of any pull-ups will not damage either IC. The internal build of i2c device SCl and SDA lines are like NPN transistors. They are Open Collectors, essentially current controlled/switched diodes. The last thing to note though, having the internal pull-ups on, when your ATMega is at 5v, and the i2c device ... WebAug 19, 2024 · For I2C, the internal pullup resistors are activated on Teensy 4.0. That is different than Teensy 3.x, where they are not used. The internal pullup resistors are much weaker than the recommended range (1K to 4.7K) for I2C, so it's not a good practice to use only the internal pullups. But unlike Teensy 3.x where I2C will not work at all (why NXP ... rubber b strap for rolex explorer 2
