Is it sufficient that using internal pullups will do the job at both 400kbps and 100kbps. You can use the Bus Pirate's on-board pull-up resistors by connecting the Vpullup (Vpu) pin to the 3. 7K pull-ups connected, or 8 for 10K, and everything should be OK. The nice thing is that the input I2c lines have pull up resistors of 10k, resulting in low influence in combination (parallel) with the 1k8 pull ups of the RPi. I2C is a popular communication protocol in embedded systems. Thus the port will normally be a 1, until the switch pulls it to 0 when you press it (because that grounds it). If you’re using a. Also, pull-up to 3v3 as the port pin may not be 5v tolerant and you can blow the port pin. Note that the 7-bit address of our slave is 0x50. For digital I/O using the i2c protocol a pull up is used so that a single pin can serve as input or output. Since the API for these two implementations is exactly the same, an application can be linked either against the software I2C implementation or the hardware I2C implementation. To do one,. As discussed in the I2C Basics module, the resistors that are commonly seen on I2C circuits sitting between the SCL and SDA lines and the voltage source are called pull up resistors.
